Greg Donaldson: Any other questions about the test ?
Greg Donaldson: 
So....there will be NO chat next week.

THis week I want to do some revision....so I will be asking lots of relevant questions..HINT HINT  &#65532;
Greg Donaldson: 
Lets start.

How does RAD  get "rapid"     wait to be asked...
Greg Donaldson: 
Chris ?
Christopher Pike: whAT DOU MEAN B THE QUESTION???
Greg Donaldson: 
What is done in the RAD approach that enables it to be FAST=RAPID ?
Greg Donaldson: 
Daniel ?
Daniel Loth: it relies on libraries
Christopher Pike: no idia
Daniel Loth: for code
Greg Donaldson: Poor answer...

David ?
Greg Donaldson: 
Emilly ?
David Turnbull: um, isn't it like using already produced code, and a CASE tool?

Daniel Loth (26/03/2007 5:17:21 PM)
i said libraries - a term used to define pre existing 'methods

Daniel Loth (26/03/2007 5:17:25 PM)
functions or modules

Greg Donaldson: 
OK...wait...
Emilly Taubman: no not really
Daniel Loth: question
Greg Donaldson: 
The RAD approach is fast because it makes use of "modules of code"...ie parts of existing solutions... so the developer does not have to rewrite the code....
Greg Donaldson: 
ie.   RAD    is used where a similar solution alreday exists...and parts can be adapted...
Daniel Loth: i've got a question
Greg Donaldson: 
So..RAD often applies in COMMON computing situations... eg database situiations.
Greg Donaldson: 
Yes Daniel ?
Daniel Loth: what was so poor about my answer?

Greg Donaldson (26/03/2007 5:34:15 PM)
;;olkes..I just realised my error

Test IS WEDNESDAY..not Thursday !!  sorry 
Greg Donaldson: Your mentors alreday have the test paper.....  sent today...you can check on that as well for me&#2504;1&#4204;&#357;;;
Greg Donaldson: Any other questions about the test ?
Greg Donaldson: 
So....there will be NO chat next week.

THis week I want to do some revision....so I will be asking lots of relevant questions..HINT HINT  &#65532;
Greg Donaldson: 
Lets start.

How does RAD  get "rapid"     wait to be asked...
Greg Donaldson: 
Chris ?
Christopher Pike: whAT DOU MEAN B THE QUESTION???
Greg Donaldson: 
What is done in the RAD approach that enables it to be FAST=RAPID ?
Greg Donaldson: 
Daniel ?
Daniel Loth: it relies on libraries
Christopher Pike: no idia
Daniel Loth: for code
Greg Donaldson: Poor answer...

David ?
Greg Donaldson: 
Emilly ?
David Turnbull: um, isn't it like using already produced code, and a CASE tool?
Greg Donaldson: yes David...good
David Turnbull: &#65532;
Greg Donaldson: Em ?  anything to add ?
Greg Donaldson: 
OK...wait...
Emilly Taubman: no not really
Daniel Loth: question
Greg Donaldson: 
The RAD approach is fast because it makes use of "modules of code"...ie parts of existing solutions... so the developer does not have to rewrite the code....
Greg Donaldson: 
ie.   RAD    is used where a similar solution alreday exists...and parts can be adapted...
Daniel Loth: i've got a question
Greg Donaldson: 
So..RAD often applies in COMMON computing situations... eg database situiations.
Greg Donaldson: 
Yes Daniel ?
Daniel Loth: what was so poor about my answer?
Daniel Loth: i said libraries - a term used to define pre existing 'methods
Daniel Loth: functions or modules
Daniel Loth: i don't see the error
Greg Donaldson: 
I only saw...."for code"   either way I wanted a fuller answer....sorry Daniel.
Greg Donaldson: 
YES...libraries of code are where the "fragments" or modules of code are often found for RAD solutions

&#65532;
Thomas Weir: Has left the conversation.
&#65532;
Greg Donaldson: 
Yes   CASE tools may be used...but the essential concept is the use of existing modules...or parts of solutions
&#65532;
Thomas Weir: Has joined the conversation.
&#65532;
Greg Donaldson: 
OK..lets move on...
Greg Donaldson: 
What is a a PROTOTYPE  ?  wait...
Greg Donaldson: 
Luke ?
Luke D'Anna: a prototype is a peice of software that has been created and can either be further developed or discarded
Luke D'Anna: it is like a pre-solution
Greg Donaldson: 
Good Luke

Best definition is  "A prototype is a WORKING MODEL"
Greg Donaldson: 
NOTE: is it not a "mock up"  or a prtend version.

It MAY be the full solution...but usually is changed...

Greg Donaldson: 
So...what do we do with a prototype ... wait ... ?
Greg Donaldson: 
Steve ?
Greg Donaldson: Thomas ?
Steven Potiris: A prototype is either discarded and a new prototype is created based off it, or a prototype may fulfill the needs of the project and be accepted as the final result.
Greg Donaldson: Good but you are missing the key point Steve.
Greg Donaldson: 
What is the 1st thing we do with it ?

Thomas ?

Tirrell ?
Thomas Weir: i dont know
Tirrell Morris: we evaluate it and see if it meets the clients requirments
Greg Donaldson: &#65532;You all should know this !!!
Greg Donaldson: 
Geting closer...
Greg Donaldson: 
The point I wanted was...that the prototype was presnted to the client for feedback !!  you MUST say that !!!!
Greg Donaldson: 
If that is what is done...what is the key characteristic needed for prototyping to work well ?
Greg Donaldson: 
Yuki ?
Yuki Igarashi: what do you mean... do you mean like, budget and teamwork...?
Greg Donaldson: No...bit vague I guess

I was fishing for...

There must be good communication between clinet and devloper !
Greg Donaldson: 
What is the usual beginning characteristic oif the client in these situations ?

Anyone ?
Daniel Loth: they aren't sure on what exactly they need
Greg Donaldson: YES...!
Greg Donaldson: 
And that is why the developer makes a "sample"  to be able to say..."is this what you want" ?  what changes would yopu like made to this prototype ?

etc
Greg Donaldson: 
Ok...moving on

Give me some characteristics of all scenarios where a STRUCTURED APPROACH might be used 
Greg Donaldson: 
Wait...
Greg Donaldson: 
JUst one characteristic Chris ?
Christopher Pike: the user knows what they need
Greg Donaldson: 
Yes...but that would also be true of all of the 4 approaches except Prototyping


Daniel ?
Daniel Loth: the client needs a system that is as flawless, efficient and bug free as possible
Daniel Loth: ugh
Daniel Loth: rofl
Greg Donaldson: Excellent
Greg Donaldson: 
anything else ?  David ?
Greg Donaldson: anyone ?  (hint: time, $$, consequences)
Luke D'Anna: the client has to have a disposable budget generally
Emilly Taubman: they are large scale projectsa
Greg Donaldson: YEs...it will be expensive...so clinet must have the $$

Greg Donaldson: 
True...but that is a siude effect...its not esessential Em
Daniel Loth: they need a system that will be heavily relied on
Daniel Loth: where flaws can mean huge problems
Greg Donaldson: YES  that last line wasd IT !!
Greg Donaldson: (TIME !!!!!)   anyone ?
David Turnbull: it'd take ages wouldn't it? because the developer has to constantly consult the client?
Greg Donaldson: So ???
Greg Donaldson: Tell me abouit the client !
David Turnbull: they have to have plenty of time?
Tirrell Morris: the requirment need ot be established before u start because changes later on are costly and time consumine

Greg Donaldson (26/03/2007 5:34:40 PM)


Greg Donaldson (26/03/2007 5:34:48 PM)
;;stopher Pike: yes &#65532;
&#2464;&#4197;&#359;;;aldson: 
So see your menmtor and find out what the arrangements are  please ASAP  &#65532;
Greg Donaldson: OK Em ?
Emilly Taubman: yeah Ours is on Wedensday afterr tutor group &#65532;

This is it !  the client must be ABLE to wait

So there would have to be a solution in place already to do the job in the meantime...
Greg Donaldson: 
OR the system is not yet working.   ie totally new organisation.

YES...libraries of code are where the "fragments" or modules of code are often found for RAD solutions

&#65532;
Thomas Weir: Has left the conversation.
&#65532;
Greg Donaldson: 
Yes   CASE tools may be used...but the essential concept is the use of existing modules...or parts of solutions
&#65532;
Thomas Weir: Has joined the conversation.
&#65532;
Greg Donaldson: 
OK..lets move on...
Greg Donaldson: 
What is a a PROTOTYPE  ?  wait...
Greg Donaldson: 
Luke ?
Luke D'Anna: a prototype is a peice of software that has been created and can either be further developed or discarded
Luke D'Anna: it is like a pre-solution
Greg Donaldson: 
Good Luke

Best definition is  "A prototype is a WORKING MODEL"
Greg Donaldson: 
NOTE: is it not a "mock up"  or a prtend version.

It MAY be the full solution...but usually is changed...

Greg Donaldson: 
So...what do we do with a prototype ... wait ... ?
Greg Donaldson: 
Steve ?
Greg Donaldson: Thomas ?
Steven Potiris: A prototype is either discarded and a new prototype is created based off it, or a prototype may fulfill the needs of the project and be accepted as the final result.
Greg Donaldson: Good but you are missing the key point Steve.
Greg Donaldson: 
What is the 1st thing we do with it ?

Thomas ?

Tirrell ?
Thomas Weir: i dont know
Tirrell Morris: we evaluate it and see if it meets the clients requirments
Greg Donaldson: &#65532;You all should know this !!!
Greg Donaldson: 
Geting closer...
Greg Donaldson: 
The point I wanted was...that the prototype was presnted to the client for feedback !!  you MUST say that !!!!
Greg Donaldson: 
If that is what is done...what is the key characteristic needed for prototyping to work well ?
Greg Donaldson: 
Yuki ?
Yuki Igarashi: what do you mean... do you mean like, budget and teamwork...?
Greg Donaldson: No...bit vague I guess

I was fishing for...

There must be good communication between clinet and devloper !
Greg Donaldson: 
What is the usual beginning characteristic oif the client in these situations ?

Anyone ?
Daniel Loth: they aren't sure on what exactly they need
Greg Donaldson: YES...!
Greg Donaldson: 
And that is why the developer makes a "sample"  to be able to say..."is this what you want" ?  what changes would yopu like made to this prototype ?

etc
Greg Donaldson: 
Ok...moving on

Give me some characteristics of all scenarios where a STRUCTURED APPROACH might be used 
Greg Donaldson: 
Wait...
Greg Donaldson: 
JUst one characteristic Chris ?
Christopher Pike: the user knows what they need
Greg Donaldson: 
Yes...but that would also be true of all of the 4 approaches except Prototyping


Daniel ?
Daniel Loth: the client needs a system that is as flawless, efficient and bug free as possible
Daniel Loth: ugh
Daniel Loth: rofl
Greg Donaldson: Excellent
Greg Donaldson: 
anything else ?  David ?
Greg Donaldson: anyone ?  (hint: time, $$, consequences)
Luke D'Anna: the client has to have a disposable budget generally
Emilly Taubman: they are large scale projectsa
Greg Donaldson: YEs...it will be expensive...so clinet must have the $$

Greg Donaldson: 
True...but that is a siude effect...its not esessential Em
Daniel Loth: they need a system that will be heavily relied on
Daniel Loth: where flaws can mean huge problems
Greg Donaldson: YES  that last line wasd IT !!
Greg Donaldson: (TIME !!!!!)   anyone ?
David Turnbull: it'd take ages wouldn't it? because the developer has to constantly consult the client?
Greg Donaldson: So ???
Greg Donaldson: Tell me abouit the client !
David Turnbull: they have to have plenty of time?
Tirrell Morris: the requirment need ot be established before u start because changes later on are costly and time consumine
Greg Donaldson: David Turnbull: they have to have plenty of time?

This is it !  the client must be ABLE to wait

So there would have to be a solution in place already to do the job in the meantime...
Greg Donaldson: 
OR the system is not yet working.   ie totally new organisation.
Greg Donaldson: 
OK...moving on....
Greg Donaldson: 
Remember ...the assignment where you were required to provide

1. A description of each approach
2. A scenario for each approach
3. A jsutification as to why that approach suits the scenario  ??


Greg Donaldson: WEll..

THAT assignment is IMPORTANT !!!!!   &#65532;
Greg Donaldson: 
Moving on....

question anyone ???
Greg Donaldson: 
So...now I am having to errect a Stop sign near my school

I will use a TOP DOWN approach

What would that mean ??       anyone ?
Emilly Taubman: that you wopuld have to break the process into more manageable steps?
Greg Donaldson: 
EXCELLENT !!
Greg Donaldson: 
THe Top Down approach...breaks a task int smaller parts...thgat can be done one at a time...
Greg Donaldson: 
Perhaps the sammler parts will be broken dopwn into smaller parts again...

Greg Donaldson: Any other questions about the test ?
Greg Donaldson: 
So....there will be NO chat next week.

THis week I want to do some revision....so I will be asking lots of relevant questions..HINT HINT  &#65532;
Greg Donaldson: 
Lets start.

How does RAD  get "rapid"     wait to be asked...
Greg Donaldson: 
Chris ?
Christopher Pike: whAT DOU MEAN B THE QUESTION???
Greg Donaldson: 
What is done in the RAD approach that enables it to be FAST=RAPID ?
Greg Donaldson: 
Daniel ?
Daniel Loth: it relies on libraries
Christopher Pike: no idia
Daniel Loth: for code
Greg Donaldson: Poor answer...

David ?
Greg Donaldson: 
Emilly ?
David Turnbull: um, isn't it like using already produced code, and a CASE tool?
Greg Donaldson: yes David...good
David Turnbull: &#65532;
Greg Donaldson: Em ?  anything to add ?
Greg Donaldson: 
OK...wait...
Emilly Taubman: no not really
Daniel Loth: question
Greg Donaldson: 
The RAD approach is fast because it makes use of "modules of code"...ie parts of existing solutions... so the developer does not have to rewrite the code....
Greg Donaldson: 
ie.   RAD    is used where a similar solution alreday exists...and parts can be adapted...
Daniel Loth: i've got a question
Greg Donaldson: 
So..RAD often applies in COMMON computing situations... eg database situiations.
Greg Donaldson: 
Yes Daniel ?
Daniel Loth: what was so poor about my answer?
Daniel Loth: i said libraries - a term used to define pre existing 'methods
Daniel Loth: functions or modules
Daniel Loth: i don't see the error
Greg Donaldson: 
I only saw...."for code"   either way I wanted a fuller answer....sorry Daniel.
Greg Donaldson: 
YES...libraries of code are where the "fragments" or modules of code are often found for RAD solutions

;;stopher Pike: yes &#65532;
&#3789;&#4197;&#359;;;aldson: 
So see your menmtor and find out what the arrangements are  please ASAP  &#65532;
Greg Donaldson: OK Em ?
Emilly Taubman: yeah Ours is on Wedensday afterr tutor group &#65532;
David Turnbull: um, on the Assessment Task Sheet it says "Wednesday  April 4th "
Greg Donaldson: 
WOOPS...sorry folkes..I just realised my error

Test IS WEDNESDAY..not Thursday !!  sorry 
Greg Donaldson: Your mentors alreday have the test paper.....  sent today...you can check on that as well for me please.
Greg Donaldson: Any other questions about the test ?
Greg Donaldson: 
So....there will be NO chat next week.

THis week I want to do some revision....so I will be asking lots of relevant questions..HINT HINT  &#65532;
Greg Donaldson: 
Lets start.

How does RAD  get "rapid"     wait to be asked...
Greg Donaldson: 
Chris ?
Christopher Pike: whAT DOU MEAN B THE QUESTION???
Greg Donaldson: 
What is done in the RAD approach that enables it to be FAST=RAPID ?
Greg Donaldson: 
Daniel ?
Daniel Loth: it relies on libraries
Christopher Pike: no idia
Daniel Loth: for code
Greg Donaldson: Poor answer...

David ?
Greg Donaldson: 
Emilly ?
David Turnbull: um, isn't it like using already produced code, and a CASE tool?
Greg Donaldson: yes David...good
David Turnbull: &#65532;
Greg Donaldson: Em ?  anything to add ?
Greg Donaldson: 
OK...wait...
Emilly Taubman: no not really
Daniel Loth: question
Greg Donaldson: 
The RAD approach is fast because it makes use of "modules of code"...ie parts of existing solutions... so the developer does not have to rewrite the code....
Greg Donaldson: 
ie.   RAD    is used where a similar solution alreday exists...and parts can be adapted...
Daniel Loth: i've got a question
Greg Donaldson: 
So..RAD often applies in COMMON computing situations... eg database situiations.
Greg Donaldson: 
Yes Daniel ?
Daniel Loth: what was so poor about my answer?
Daniel Loth: i said libraries - a term used to define pre existing 'methods
Daniel Loth: functions or modules
Daniel Loth: i don't see the error
Greg Donaldson: 
I only saw...."for code"   either way I wanted a fuller answer....sorry Daniel.
Greg Donaldson: 
YES...libraries of code are where the "fragments" or modules of code are often found for RAD solutions

&#65532;
Thomas Weir: Has left the conversation.
&#65532;
Greg Donaldson: 
Yes   CASE tools may be used...but the essential concept is the use of existing modules...or parts of solutions
&#65532;
Thomas Weir: Has joined the conversation.
&#65532;
Greg Donaldson: 
OK..lets move on...
Greg Donaldson: 
What is a a PROTOTYPE  ?  wait...
Greg Donaldson: 
Luke ?
Luke D'Anna: a prototype is a peice of software that has been created and can either be further developed or discarded
Luke D'Anna: it is like a pre-solution
Greg Donaldson: 
Good Luke

Best definition is  "A prototype is a WORKING MODEL"
Greg Donaldson: 
NOTE: is it not a "mock up"  or a prtend version.

It MAY be the full solution...but usually is changed...

Greg Donaldson: 
So...what do we do with a prototype ... wait ... ?
Greg Donaldson: 
Steve ?
Greg Donaldson: Thomas ?
Steven Potiris: A prototype is either discarded and a new prototype is created based off it, or a prototype may fulfill the needs of the project and be accepted as the final result.
Greg Donaldson: Good but you are missing the key point Steve.
Greg Donaldson: 
What is the 1st thing we do with it ?

Thomas ?

Tirrell ?
Thomas Weir: i dont know
Tirrell Morris: we evaluate it and see if it meets the clients requirments
Greg Donaldson: &#65532;You all should know this !!!
Greg Donaldson: 
Geting closer...
Greg Donaldson: 
The point I wanted was...that the prototype was presnted to the client for feedback !!  you MUST say that !!!!
Greg Donaldson: 
If that is what is done...what is the key characteristic needed for prototyping to work well ?
Greg Donaldson: 
Yuki ?
Yuki Igarashi: what do you mean... do you mean like, budget and teamwork...?
Greg Donaldson: No...bit vague I guess

I was fishing for...

There must be good communication between clinet and devloper !
Greg Donaldson: 
What is the usual beginning characteristic oif the client in these situations ?

Anyone ?
Daniel Loth: they aren't sure on what exactly they need
Greg Donaldson: YES...!
Greg Donaldson: 
And that is why the developer makes a "sample"  to be able to say..."is this what you want" ?  what changes would yopu like made to this prototype ?

etc
Greg Donaldson: 
Ok...moving on

Give me some characteristics of all scenarios where a STRUCTURED APPROACH might be used 
Greg Donaldson: 
Wait...
Greg Donaldson: 
JUst one characteristic Chris ?
Christopher Pike: the user knows what they need
Greg Donaldson: 
Yes...but that would also be true of all of the 4 approaches except Prototyping


Daniel ?
Daniel Loth: the client needs a system that is as flawless, efficient and bug free as possible
Daniel Loth: ugh
Daniel Loth: rofl
Greg Donaldson: Excellent
Greg Donaldson: 
anything else ?  David ?
Greg Donaldson: anyone ?  (hint: time, $$, consequences)
Luke D'Anna: the client has to have a disposable budget generally
Emilly Taubman: they are large scale projectsa
Greg Donaldson: YEs...it will be expensive...so clinet must have the $$

Greg Donaldson: 
True...but that is a siude effect...its not esessential Em
Daniel Loth: they need a system that will be heavily relied on
Daniel Loth: where flaws can mean huge problems
Greg Donaldson: YES  that last line wasd IT !!
Greg Donaldson: (TIME !!!!!)   anyone ?
David Turnbull: it'd take ages wouldn't it? because the developer has to constantly consult the client?
Greg Donaldson: So ???
Greg Donaldson: Tell me abouit the client !
David Turnbull: they have to have plenty of time?
Tirrell Morris: the requirment need ot be established before u start because changes later on are costly and time consumine
Greg Donaldson: David Turnbull: they have to have plenty of time?

This is it !  the client must be ABLE to wait

So there would have to be a solution in place already to do the job in the meantime...
Greg Donaldson: 
OR the system is not yet working.   ie totally new organisation.
Greg Donaldson: 
OK...moving on....
Greg Donaldson: 
Remember ...the assignment where you were required to provide

1. A description of each approach
2. A scenario for each approach
3. A jsutification as to why that approach suits the scenario  ??


Greg Donaldson: WEll..

THAT assignment is IMPORTANT !!!!!   &#65532;
Greg Donaldson: 
Moving on....

question anyone ???
Greg Donaldson: 
So...now I am having to errect a Stop sign near my school

I will use a TOP DOWN approach

What would that mean ??       anyone ?
Emilly Taubman: that you wopuld have to break the process into more manageable steps?
Greg Donaldson: 
EXCELLENT !!
Greg Donaldson: 
THe Top Down approach...breaks a task int smaller parts...thgat can be done one at a time...
Greg Donaldson: 
Perhaps the sammler parts will be broken dopwn into smaller parts again...
Greg Donaldson: 
That will do there

Greg Donaldson: 
What is the largest decimal number that can be stores in a 3 bit binary format ?

wait,...
Greg Donaldson: 
Tirrell ??
Tirrell Morris: 7
Greg Donaldson: 
Good...tell us hpow or why please Luke 
Greg Donaldson: how
Luke D'Anna: each 1 represents a place value
Greg Donaldson: So ?
Luke D'Anna: the first 1 is 2^0
Luke D'Anna: the second 2^1
Greg Donaldson: (at the right)
Luke D'Anna: and third 2^3
Greg Donaldson: (middle 1)
Luke D'Anna: so 1+2+4 = 7
Greg Donaldson: 
Can you tell us ijn ONE send Luke ?

2^2   2^1  2^0
1        1       1
4     + 2   +  1        =7
Greg Donaldson: 
A liitle like this

   Biggest binary is 111
   4   2  1
   1   1   1
   
Gives    1x4 +  1x2 + 1x1 = 7

Greg Donaldson: 
OK moving on

What is the   111 (octal) equivalent to in DEcimal ?   wait

I only saw...."for code"   either way I wanted a fuller answer....sorry Daniel.
Greg Donaldson: 
YES...libraries of code are where the "fragments" or modules of code are often found for RAD solutions

&#65532;
Thomas Weir: Has left the conversation.
&#65532;
Greg Donaldson: 
Yes   CASE tools may be used...but the essential concept is the use of existing modules...or parts of solutions
&#65532;
Thomas Weir: Has joined the conversation.
&#65532;
Greg Donaldson: 
OK..lets move on...
Greg Donaldson: 
What is a a PROTOTYPE  ?  wait...
Greg Donaldson: 
Luke ?
Luke D'Anna: a prototype is a peice of software that has been created and can either be further developed or discarded
Luke D'Anna: it is like a pre-solution
Greg Donaldson: 
Good Luke

Best definition is  "A prototype is a WORKING MODEL"
Greg Donaldson: 
NOTE: is it not a "mock up"  or a prtend version.

It MAY be the full solution...but usually is changed...

Greg Donaldson: 
So...what do we do with a prototype ... wait ... ?
Greg Donaldson: 
Steve ?
Greg Donaldson: Thomas ?
Steven Potiris: A prototype is either discarded and a new prototype is created based off it, or a prototype may fulfill the needs of the project and be accepted as the final result.
Greg Donaldson: Good but you are missing the key point Steve.
Greg Donaldson: 
What is the 1st thing we do with it ?

Thomas ?

Tirrell ?
Thomas Weir: i dont know
Tirrell Morris: we evaluate it and see if it meets the clients requirments
Greg Donaldson: &#65532;You all should know this !!!
Greg Donaldson: 
Geting closer...
Greg Donaldson: 
The point I wanted was...that the prototype was presnted to the client for feedback !!  you MUST say that !!!!
Greg Donaldson: 
If that is what is done...what is the key characteristic needed for prototyping to work well ?
Greg Donaldson: 
Yuki ?
Yuki Igarashi: what do you mean... do you mean like, budget and teamwork...?
Greg Donaldson: No...bit vague I guess

I was fishing for...

There must be good communication between clinet and devloper !
Greg Donaldson: 
What is the usual beginning characteristic oif the client in these situations ?

Anyone ?
Daniel Loth: they aren't sure on what exactly they need
Greg Donaldson: YES...!
Greg Donaldson: 
And that is why the developer makes a "sample"  to be able to say..."is this what you want" ?  what changes would yopu like made to this prototype ?

etc
Greg Donaldson: 
Ok...moving on

Give me some characteristics of all scenarios where a STRUCTURED APPROACH might be used 
Greg Donaldson: 
Wait...
Greg Donaldson: 
JUst one characteristic Chris ?
Christopher Pike: the user knows what they need
Greg Donaldson: 
Yes...but that would also be true of all of the 4 approaches except Prototyping


Daniel ?
Daniel Loth: the client needs a system that is as flawless, efficient and bug free as possible
Daniel Loth: ugh
Daniel Loth: rofl
Greg Donaldson: Excellent
Greg Donaldson: 
anything else ?  David ?
Greg Donaldson: anyone ?  (hint: time, $$, consequences)
Luke D'Anna: the client has to have a disposable budget generally
Emilly Taubman: they are large scale projectsa
Greg Donaldson: YEs...it will be expensive...so clinet must have the $$

Greg Donaldson: 
True...but that is a siude effect...its not esessential Em
Daniel Loth: they need a system that will be heavily relied on
Daniel Loth: where flaws can mean huge problems
Greg Donaldson: YES  that last line wasd IT !!
Greg Donaldson: (TIME !!!!!)   anyone ?
David Turnbull: it'd take ages wouldn't it? because the developer has to constantly consult the client?
Greg Donaldson: So ???
Greg Donaldson: Tell me abouit the client !
David Turnbull: they have to have plenty of time?
Tirrell Morris: the requirment need ot be established before u start because changes later on are costly and time consumine
Greg Donaldson: David Turnbull: they have to have plenty of time?

This is it !  the client must be ABLE to wait

So there would have to be a solution in place already to do the job in the meantime...
Greg Donaldson: 
OR the system is not yet working.   ie totally new organisation.
Greg Donaldson: 
OK...moving on....
Greg Donaldson: 
Remember ...the assignment where you were required to provide

1. A description of each approach
2. A scenario for each approach
3. A jsutification as to why that approach suits the scenario  ??


Greg Donaldson: WEll..

THAT assignment is IMPORTANT !!!!!   &#65532;
Greg Donaldson: 
Moving on....

question anyone ???
Greg Donaldson: 
So...now I am having to errect a Stop sign near my school

I will use a TOP DOWN approach

What would that mean ??       anyone ?
Emilly Taubman: that you wopuld have to break the process into more manageable steps?
Greg Donaldson: 
EXCELLENT !!
Greg Donaldson: 
THe Top Down approach...breaks a task int smaller parts...thgat can be done one at a time...
Greg Donaldson: 
Perhaps the sammler parts will be broken dopwn into smaller parts again...
Greg Donaldson: 
That will do there

Greg Donaldson: 
What is the largest decimal number that can be stores in a 3 bit binary format ?

wait,...
Greg Donaldson: 
Tirrell ??
Tirrell Morris: 7
Greg Donaldson: 
Good...tell us hpow or why please Luke 
Greg Donaldson: how
Luke D'Anna: each 1 represents a place value
Greg Donaldson: So ?
Luke D'Anna: the first 1 is 2^0
Luke D'Anna: the second 2^1
Greg Donaldson: (at the right)
Luke D'Anna: and third 2^3
Greg Donaldson: (middle 1)
Luke D'Anna: so 1+2+4 = 7
Greg Donaldson: 
Can you tell us ijn ONE send Luke ?

Emilly Taubman: yeah Ours is on Wedensday afterr tutor group &#65532;
David Turnbull: um, on the Assessment Task Sheet it says "Wednesday  April 4th "
Greg Donaldson: 
WOOPS...sorry folkes..I just realised my error

Test IS WEDNESDAY..not Thursday !!  sorry 
Greg Donaldson: Your mentors alreday have the test paper.....  sent today...you can check on that as well for me please.
Greg Donaldson: Any other questions about the test ?
Greg Donaldson: 
So....there will be NO chat next week.

THis week I want to do some revision....so I will be asking lots of relevant questions..HINT HINT  &#65532;
Greg Donaldson: 
Lets start.

How does RAD  get "rapid"     wait to be asked...
Greg Donaldson: 
Chris ?
Christopher Pike: whAT DOU MEAN B THE QUESTION???
Greg Donaldson: 
What is done in the RAD approach that enables it to be FAST=RAPID ?
Greg Donaldson: 
Daniel ?
Daniel Loth: it relies on libraries
Christopher Pike: no idia
Daniel Loth: for code
Greg Donaldson: Poor answer...

David ?
Greg Donaldson: 
Emilly ?
David Turnbull: um, isn't it like using already produced code, and a CASE tool?
Greg Donaldson: yes David...good
David Turnbull: &#65532;
Greg Donaldson: Em ?  anything to add ?
Greg Donaldson: 
OK...wait...
Emilly Taubman: no not really
Daniel Loth: question
Greg Donaldson: 
The RAD approach is fast because it makes use of "modules of code"...ie parts of existing solutions... so the developer does not have to rewrite the code....
Greg Donaldson: 
ie.   RAD    is used where a similar solution alreday exists...and parts can be adapted...
Daniel Loth: i've got a question
Greg Donaldson: 
So..RAD often applies in COMMON computing situations... eg database situiations.
Greg Donaldson: 
Yes Daniel ?
Daniel Loth: what was so poor about my answer?
Daniel Loth: i said libraries - a term used to define pre existing 'methods
Daniel Loth: functions or modules
Daniel Loth: i don't see the error
Greg Donaldson: 
I only saw...."for code"   either way I wanted a fuller answer....sorry Daniel.

Greg Donaldson (26/03/2007 5:51:15 PM)
;;stopher Pike: yes &#65532;
&#3300;&#4197;&#359;;;aldson: 
So see your menmtor and find out what the arrangements are  please ASAP  &#65532;
Greg Donaldson: OK Em ?
Emilly Taubman: yeah Ours is on Wedensday afterr tutor group &#65532;
David Turnbull: um, on the Assessment Task Sheet it says "Wednesday  April 4th "
Greg Donaldson: 
WOOPS...sorry folkes..I just realised my error

Test IS WEDNESDAY..not Thursday !!  sorry 
Greg Donaldson: Your mentors alreday have the test paper.....  sent today...you can check on that as well for me please.
Greg Donaldson: Any other questions about the test ?
Greg Donaldson: 
So....there will be NO chat next week.

THis week I want to do some revision....so I will be asking lots of relevant questions..HINT HINT  &#65532;
Greg Donaldson: 
Lets start.

How does RAD  get "rapid"     wait to be asked...
Greg Donaldson: 
Chris ?
Christopher Pike: whAT DOU MEAN B THE QUESTION???
Greg Donaldson: 
What is done in the RAD approach that enables it to be FAST=RAPID ?
Greg Donaldson: 
Daniel ?
Daniel Loth: it relies on libraries
Christopher Pike: no idia
Daniel Loth: for code
Greg Donaldson: Poor answer...

David ?
Greg Donaldson: 
Emilly ?
David Turnbull: um, isn't it like using already produced code, and a CASE tool?
Greg Donaldson: yes David...good
David Turnbull: &#65532;
Greg Donaldson: Em ?  anything to add ?
Greg Donaldson: 
OK...wait...
Emilly Taubman: no not really
Daniel Loth: question
Greg Donaldson: 
The RAD approach is fast because it makes use of "modules of code"...ie parts of existing solutions... so the developer does not have to rewrite the code....
Greg Donaldson: 
ie.   RAD    is used where a similar solution alreday exists...and parts can be adapted...
Daniel Loth: i've got a question
Greg Donaldson: 
So..RAD often applies in COMMON computing situations... eg database situiations.
Greg Donaldson: 
Yes Daniel ?
Daniel Loth: what was so poor about my answer?
Daniel Loth: i said libraries - a term used to define pre existing 'methods
Daniel Loth: functions or modules
Daniel Loth: i don't see the error
Greg Donaldson: 
I only saw...."for code"   either way I wanted a fuller answer....sorry Daniel.
Greg Donaldson: 
YES...libraries of code are where the "fragments" or modules of code are often found for RAD solutions

&#65532;
Thomas Weir: Has left the conversation.
&#65532;
Greg Donaldson: 
Yes   CASE tools may be used...but the essential concept is the use of existing modules...or parts of solutions
&#65532;
Thomas Weir: Has joined the conversation.
&#65532;
Greg Donaldson: 
OK..lets move on...
Greg Donaldson: 
What is a a PROTOTYPE  ?  wait...
Greg Donaldson: 
Luke ?
Luke D'Anna: a prototype is a peice of software that has been created and can either be further developed or discarded
Luke D'Anna: it is like a pre-solution
Greg Donaldson: 
Good Luke

Best definition is  "A prototype is a WORKING MODEL"
Greg Donaldson: 
NOTE: is it not a "mock up"  or a prtend version.

It MAY be the full solution...but usually is changed...

Greg Donaldson: 
So...what do we do with a prototype ... wait ... ?
Greg Donaldson: 
Steve ?
Greg Donaldson: Thomas ?
Steven Potiris: A prototype is either discarded and a new prototype is created based off it, or a prototype may fulfill the needs of the project and be accepted as the final result.
Greg Donaldson: Good but you are missing the key point Steve.
Greg Donaldson: 
What is the 1st thing we do with it ?

Thomas ?

Tirrell ?
Thomas Weir: i dont know
Tirrell Morris: we evaluate it and see if it meets the clients requirments
Greg Donaldson: &#65532;You all should know this !!!
Greg Donaldson: 
Geting closer...
Greg Donaldson: 
The point I wanted was...that the prototype was presnted to the client for feedback !!  you MUST say that !!!!
Greg Donaldson: 
If that is what is done...what is the key characteristic needed for prototyping to work well ?
Greg Donaldson: 
Yuki ?
Yuki Igarashi: what do you mean... do you mean like, budget and teamwork...?
Greg Donaldson: No...bit vague I guess

I was fishing for...

There must be good communication between clinet and devloper !
Greg Donaldson: 
What is the usual beginning characteristic oif the client in these situations ?

Anyone ?
Daniel Loth: they aren't sure on what exactly they need
Greg Donaldson: YES...!
Greg Donaldson: 
And that is why the developer makes a "sample"  to be able to say..."is this what you want" ?  what changes would yopu like made to this prototype ?

etc
Greg Donaldson: 
Ok...moving on

Give me some characteristics of all scenarios where a STRUCTURED APPROACH might be used 
Greg Donaldson: 
Wait...
Greg Donaldson: 
JUst one characteristic Chris ?
Christopher Pike: the user knows what they need
Greg Donaldson: 
Yes...but that would also be true of all of the 4 approaches except Prototyping


Daniel ?
Daniel Loth: the client needs a system that is as flawless, efficient and bug free as possible
Daniel Loth: ugh
Daniel Loth: rofl
Greg Donaldson: Excellent
Greg Donaldson: 
anything else ?  David ?
Greg Donaldson: anyone ?  (hint: time, $$, consequences)
Luke D'Anna: the client has to have a disposable budget generally
Emilly Taubman: they are large scale projectsa
Greg Donaldson: YEs...it will be expensive...so clinet must have the $$

Greg Donaldson: 
True...but that is a siude effect...its not esessential Em
Daniel Loth: they need a system that will be heavily relied on
Daniel Loth: where flaws can mean huge problems
Greg Donaldson: YES  that last line wasd IT !!
Greg Donaldson: (TIME !!!!!)   anyone ?
David Turnbull: it'd take ages wouldn't it? because the developer has to constantly consult the client?
Greg Donaldson: So ???
Greg Donaldson: Tell me abouit the client !
David Turnbull: they have to have plenty of time?
Tirrell Morris: the requirment need ot be established before u start because changes later on are costly and time consumine
Greg Donaldson: David Turnbull: they have to have plenty of time?

This is it !  the client must be ABLE to wait

So there would have to be a solution in place already to do the job in the meantime...
Greg Donaldson: 
OR the system is not yet working.   ie totally new organisation.
Greg Donaldson: 
OK...moving on....
Greg Donaldson: 
Remember ...the assignment where you were required to provide

1. A description of each approach
2. A scenario for each approach
3. A jsutification as to why that approach suits the scenario  ??


Greg Donaldson: WEll..

THAT assignment is IMPORTANT !!!!!   &#65532;
Greg Donaldson: 
Moving on....

question anyone ???
Greg Donaldson: 
So...now I am having to errect a Stop sign near my school

I will use a TOP DOWN approach

What would that mean ??       anyone ?
Emilly Taubman: that you wopuld have to break the process into more manageable steps?
Greg Donaldson: 
EXCELLENT !!
Greg Donaldson: 
THe Top Down approach...breaks a task int smaller parts...thgat can be done one at a time...
Greg Donaldson: 
Perhaps the sammler parts will be broken dopwn into smaller parts again...
Greg Donaldson: 
That will do there

Greg Donaldson: 
What is the largest decimal number that can be stores in a 3 bit binary format ?

wait,...
Greg Donaldson: 
Tirrell ??
Tirrell Morris: 7
Greg Donaldson: 
Good...tell us hpow or why please Luke 
Greg Donaldson: how
Luke D'Anna: each 1 represents a place value
Greg Donaldson: So ?
Luke D'Anna: the first 1 is 2^0
Luke D'Anna: the second 2^1
Greg Donaldson: (at the right)
Luke D'Anna: and third 2^3
Greg Donaldson: (middle 1)
Luke D'Anna: so 1+2+4 = 7
Greg Donaldson: 
Can you tell us ijn ONE send Luke ?

&#65532;
Luke D'Anna: the highest digit represent in binary is 111
2^2   2^1  2^0
1        1       1
4     + 2   +  1        =7
Greg Donaldson: 
A liitle like this

   Biggest binary is 111
   4   2  1
   1   1   1
   
Gives    1x4 +  1x2 + 1x1 = 7

Greg Donaldson: 
OK moving on

What is the   111 (octal) equivalent to in DEcimal ?   wait 
&#65532;
Emilly Taubman: Has joined the conversation.
&#65532;
Greg Donaldson: What is the   111 (octal) equivalent to in DEcimal ?   wait 

Steve ?
Steven Potiris: 7?
Greg Donaldson: NUP...OCTAL !!!
Greg Donaldson: 
THomas ?
Thomas Weir: 73?
Greg Donaldson: 
OK  show us how please Yuki 
Yuki Igarashi: 3
Greg Donaldson: 
Octal   111

   64     8    1
     1      1     1

= 1x64  +  1x8  +  1x1  =  73
Greg Donaldson: 
Next...
Greg Donaldson: 
Consider   hex  2A

what is the DECIMAL equivalent here ?   wait
Greg Donaldson: 
David ?
David Turnbull: 12 i think
Greg Donaldson: 
Nup

Tirrell ?

      
Greg Donaldson: Chris ?
Greg Donaldson: 
Ok...listen up....

Greg Donaldson: YES...!
Greg Donaldson: 
And that is why the developer makes a "sample"  to be able to say..."is this what you want" ?  what changes would yopu like made to this prototype ?

etc
Greg Donaldson: 
Ok...moving on

Give me some characteristics of all scenarios where a STRUCTURED APPROACH might be used 
Greg Donaldson: 
Wait...
Greg Donaldson: 
JUst one characteristic Chris ?
Christopher Pike: the user knows what they need
Greg Donaldson: 
Yes...but that would also be true of all of the 4 approaches except Prototyping


Daniel ?
Daniel Loth: the client needs a system that is as flawless, efficient and bug free as possible
Daniel Loth: ugh
Daniel Loth: rofl
Greg Donaldson: Excellent
Greg Donaldson: 
anything else ?  David ?
Greg Donaldson: anyone ?  (hint: time, $$, consequences)
Luke D'Anna: the client has to have a disposable budget generally
Emilly Taubman: they are large scale projectsa
Greg Donaldson: YEs...it will be expensive...so clinet must have the $$

Greg Donaldson: 
True...but that is a siude effect...its not esessential Em
Daniel Loth: they need a system that will be heavily relied on
Daniel Loth: where flaws can mean huge problems
Greg Donaldson: YES  that last line wasd IT !!
Greg Donaldson: (TIME !!!!!)   anyone ?
David Turnbull: it'd take ages wouldn't it? because the developer has to constantly consult the client?
Greg Donaldson: So ???
Greg Donaldson: Tell me abouit the client !
David Turnbull: they have to have plenty of time?
Tirrell Morris: the requirment need ot be established before u start because changes later on are costly and time consumine
Greg Donaldson: David Turnbull: they have to have plenty of time?

This is it !  the client must be ABLE to wait

So there would have to be a solution in place already to do the job in the meantime...
Greg Donaldson: 
OR the system is not yet working.   ie totally new organisation.
Greg Donaldson: 
OK...moving on....
Greg Donaldson: 
Remember ...the assignment where you were required to provide

1. A description of each approach
2. A scenario for each approach
3. A jsutification as to why that approach suits the scenario  ??


Greg Donaldson: WEll..

THAT assignment is IMPORTANT !!!!!   &#65532;
Greg Donaldson: 
Moving on....

question anyone ???
Greg Donaldson: 
So...now I am having to errect a Stop sign near my school

I will use a TOP DOWN approach

What would that mean ??       anyone ?
Emilly Taubman: that you wopuld have to break the process into more manageable steps?
Greg Donaldson: 
EXCELLENT !!
Greg Donaldson: 
THe Top Down approach...breaks a task int smaller parts...thgat can be done one at a time...
Greg Donaldson: 
Perhaps the sammler parts will be broken dopwn into smaller parts again...
Greg Donaldson: 
That will do there

Greg Donaldson: 
What is the largest decimal number that can be stores in a 3 bit binary format ?

wait,...
Greg Donaldson: 
Tirrell ??
Tirrell Morris: 7
Greg Donaldson: 
Good...tell us hpow or why please Luke 
Greg Donaldson: how
Luke D'Anna: each 1 represents a place value
Greg Donaldson: So ?
Luke D'Anna: the first 1 is 2^0
Luke D'Anna: the second 2^1
Greg Donaldson: (at the right)
Luke D'Anna: and third 2^3
Greg Donaldson: (middle 1)
Luke D'Anna: so 1+2+4 = 7
Greg Donaldson: 
Can you tell us ijn ONE send Luke ?

1        1       1
4     + 2   +  1        =7
Greg Donaldson: 
A liitle like this

   Biggest binary is 111
   4   2  1
   1   1   1
   
Gives    1x4 +  1x2 + 1x1 = 7

Greg Donaldson: 
OK moving on

What is the   111 (octal) equivalent to in DEcimal ?   wait 
&#65532;

Greg Donaldson: NUP...OCTAL !!!
Greg Donaldson: 
THomas ?
Thomas Weir: 73?
Greg Donaldson: 
OK  show us how please Yuki 
Yuki Igarashi: 3
Greg Donaldson: 
Octal   111

   64     8    1
     1      1     1

= 1x64  +  1x8  +  1x1  =  73
Greg Donaldson: 
Next...
Greg Donaldson: 
Consider   hex  2A

what is the DECIMAL equivalent here ?   wait
Greg Donaldson: 
David ?
David Turnbull: 12 i think
Greg Donaldson: 
Nup

Tirrell ?

      
Greg Donaldson: Chris ?
Greg Donaldson: 
Ok...listen up....
Greg Donaldson: 
In hex what are the place value headings ?   anyone ?
Christopher Pike: me
Greg Donaldson: 
Yes Chris?
Greg Donaldson: just 2 or 3 will do
Greg Donaldson: anyone ?
Christopher Pike: just a sec
Emilly Taubman: 1,2,3,4,5,6,7,8,9, A,B,C,D,E,F             
Steven Potiris: 256 16 1
Luke D'Anna: 512   256   16   1
Emilly Taubman: haha im so dumb
Greg Donaldson: No Em  they are the DIGITS we use
Greg Donaldson: 
Yes Stev, Luke
Greg Donaldson: 
Ok so we have

    2A  ..
Christopher Pike: 4096, 256, 16, 1

Greg Donaldson: (Good Chris)


    16    1
     2     A
Greg Donaldson: 
ie

   16   1
    2   10      (A is 10)
Greg Donaldson: 

So we ahve

   2x16  + 10x1  =    ??? anyone ?
Yuki Igarashi: 42
Steven Potiris: 42
Emilly Taubman: 42
Thomas Weir: 42
Luke D'Anna: 42
Greg Donaldson: YES 42


try another

Hex A8     decimal ??   wait to be asked 
Emilly Taubman: sir if i do it a different way and still get the same answer can i do it my way
Greg Donaldson: 
   (yes thats fine Em...as long as I can see and understand what you are doing)
    
Greg Donaldson: 
David ?
Greg Donaldson: 
Thomas ?
Thomas Weir: 168
Greg Donaldson: 
Good



   16    1
    A    8

ie

    16   1
    10   8

= 10x16 +  8x1  = 168
Greg Donaldson: 
OK

Consider    110011001   convert to HEX please... wait
Greg Donaldson: 
Yuki ?
Yuki Igarashi: 199?

&#5508;&#4197;&#359;;;aldson: 
So see your menmtor and find out what the arrangements are  please ASAP  &#65532;
Greg Donaldson: OK Em ?
Emilly Taubman: yeah Ours is on Wedensday afterr tutor group &#65532;
David Turnbull: um, on the Assessment Task Sheet it says "Wednesday  April 4th "
Greg Donaldson: 
WOOPS...sorry folkes..I just realised my error

Test IS WEDNESDAY..not Thursday !!  sorry 
Greg Donaldson: Your mentors alreday have the test paper.....  sent today...you can check on that as well for me please.
Greg Donaldson: Any other questions about the test ?
Greg Donaldson: 
So....there will be NO chat next week.

THis week I want to do some revision....so I will be asking lots of relevant questions..HINT HINT  &#65532;
Greg Donaldson: 
Lets start.

How does RAD  get "rapid"     wait to be asked...
Greg Donaldson: 
Chris ?
Christopher Pike: whAT DOU MEAN B THE QUESTION???
Greg Donaldson: 
What is done in the RAD approach that enables it to be FAST=RAPID ?
Greg Donaldson: 
Daniel ?
Daniel Loth: it relies on libraries
Christopher Pike: no idia
Daniel Loth: for code
Greg Donaldson: Poor answer...

David ?
Greg Donaldson: 
Emilly ?
David Turnbull: um, isn't it like using already produced code, and a CASE tool?
Greg Donaldson: yes David...good
David Turnbull: &#65532;
Greg Donaldson: Em ?  anything to add ?
Greg Donaldson: 
OK...wait...
Emilly Taubman: no not really
Daniel Loth: question
Greg Donaldson: 
The RAD approach is fast because it makes use of "modules of code"...ie parts of existing solutions... so the developer does not have to rewrite the code....
Greg Donaldson: 
ie.   RAD    is used where a similar solution alreday exists...and parts can be adapted...
Daniel Loth: i've got a question
Greg Donaldson: 
So..RAD often applies in COMMON computing situations... eg database situiations.
Greg Donaldson: 
Yes Daniel ?
Daniel Loth: what was so poor about my answer?
Daniel Loth: i said libraries - a term used to define pre existing 'methods
Daniel Loth: functions or modules
Daniel Loth: i don't see the error
Greg Donaldson: 
I only saw...."for code"   either way I wanted a fuller answer....sorry Daniel.
Greg Donaldson: 
YES...libraries of code are where the "fragments" or modules of code are often found for RAD solutions

&#65532;
Thomas Weir: Has left the conversation.
&#65532;
Greg Donaldson: 
Yes   CASE tools may be used...but the essential concept is the use of existing modules...or parts of solutions
&#65532;
Thomas Weir: Has joined the conversation.
&#65532;
Greg Donaldson: 
OK..lets move on...
Greg Donaldson: 
What is a a PROTOTYPE  ?  wait...
Greg Donaldson: 
Luke ?
Luke D'Anna: a prototype is a peice of software that has been created and can either be further developed or discarded
Luke D'Anna: it is like a pre-solution
Greg Donaldson: 
Good Luke

Best definition is  "A prototype is a WORKING MODEL"
Greg Donaldson: 
NOTE: is it not a "mock up"  or a prtend version.

It MAY be the full solution...but usually is changed...

Greg Donaldson: 
So...what do we do with a prototype ... wait ... ?
Greg Donaldson: 
Steve ?
Greg Donaldson: Thomas ?
Steven Potiris: A prototype is either discarded and a new prototype is created based off it, or a prototype may fulfill the needs of the project and be accepted as the final result.
Greg Donaldson: Good but you are missing the key point Steve.
Greg Donaldson: 
What is the 1st thing we do with it ?

Thomas ?

Tirrell ?
Thomas Weir: i dont know
Tirrell Morris: we evaluate it and see if it meets the clients requirments
Greg Donaldson: &#65532;You all should know this !!!
Greg Donaldson: 
Geting closer...
Greg Donaldson: 
The point I wanted was...that the prototype was presnted to the client for feedback !!  you MUST say that !!!!
Greg Donaldson: 
If that is what is done...what is the key characteristic needed for prototyping to work well ?
Greg Donaldson: 
Yuki ?
Yuki Igarashi: what do you mean... do you mean like, budget and teamwork...?
Greg Donaldson: No...bit vague I guess

I was fishing for...

There must be good communication between clinet and devloper !
Greg Donaldson: 
What is the usual beginning characteristic oif the client in these situations ?

Anyone ?
Daniel Loth: they aren't sure on what exactly they need
Greg Donaldson: YES...!
Greg Donaldson: 
And that is why the developer makes a "sample"  to be able to say..."is this what you want" ?  what changes would yopu like made to this prototype ?

etc
Greg Donaldson: 
Ok...moving on

Give me some characteristics of all scenarios where a STRUCTURED APPROACH might be used 
Greg Donaldson: 
Wait...
Greg Donaldson: 
JUst one characteristic Chris ?
Christopher Pike: the user knows what they need
Greg Donaldson: 
Yes...but that would also be true of all of the 4 approaches except Prototyping


Daniel ?
Daniel Loth: the client needs a system that is as flawless, efficient and bug free as possible
Daniel Loth: ugh
Daniel Loth: rofl
Greg Donaldson: Excellent
Greg Donaldson: 
anything else ?  David ?
Greg Donaldson: anyone ?  (hint: time, $$, consequences)
Luke D'Anna: the client has to have a disposable budget generally
Emilly Taubman: they are large scale projectsa
Greg Donaldson: YEs...it will be expensive...so clinet must have the $$

Greg Donaldson: 
True...but that is a siude effect...its not esessential Em
Daniel Loth: they need a system that will be heavily relied on
Daniel Loth: where flaws can mean huge problems
Greg Donaldson: YES  that last line wasd IT !!
Greg Donaldson: (TIME !!!!!)   anyone ?
David Turnbull: it'd take ages wouldn't it? because the developer has to constantly consult the client?
Greg Donaldson: So ???
Greg Donaldson: Tell me abouit the client !
David Turnbull: they have to have plenty of time?
Tirrell Morris: the requirment need ot be established before u start because changes later on are costly and time consumine
Greg Donaldson: David Turnbull: they have to have plenty of time?

This is it !  the client must be ABLE to wait

So there would have to be a solution in place already to do the job in the meantime...
Greg Donaldson: 
OR the system is not yet working.   ie totally new organisation.
Greg Donaldson: 
OK...moving on....
Greg Donaldson: 
Remember ...the assignment where you were required to provide

1. A description of each approach
2. A scenario for each approach
3. A jsutification as to why that approach suits the scenario  ??


Greg Donaldson: WEll..

THAT assignment is IMPORTANT !!!!!   &#65532;
Greg Donaldson: 
Moving on....

question anyone ???
Greg Donaldson: 
So...now I am having to errect a Stop sign near my school

I will use a TOP DOWN approach

What would that mean ??       anyone ?
Emilly Taubman: that you wopuld have to break the process into more manageable steps?
Greg Donaldson: 
EXCELLENT !!
Greg Donaldson: 
THe Top Down approach...breaks a task int smaller parts...thgat can be done one at a time...
Greg Donaldson: 
Perhaps the sammler parts will be broken dopwn into smaller parts again...
Greg Donaldson: 
That will do there

Greg Donaldson: 
What is the largest decimal number that can be stores in a 3 bit binary format ?

wait,...
Greg Donaldson: 
Tirrell ??
Tirrell Morris: 7
Greg Donaldson: 
Good...tell us hpow or why please Luke 
Greg Donaldson: how
Luke D'Anna: each 1 represents a place value
Greg Donaldson: So ?
Luke D'Anna: the first 1 is 2^0
Luke D'Anna: the second 2^1
Greg Donaldson: (at the right)
Luke D'Anna: and third 2^3
Greg Donaldson: (middle 1)
Luke D'Anna: so 1+2+4 = 7

Greg Donaldson: 
Ok so we have

    2A  ..
Christopher Pike: 4096, 256, 16, 1

Greg Donaldson: (Good Chris)


    16    1
     2     A
Greg Donaldson: 
ie

   16   1
    2   10      (A is 10)
Greg Donaldson: 

So we ahve

   2x16  + 10x1  =    ??? anyone ?
Yuki Igarashi: 42
Steven Potiris: 42
Emilly Taubman: 42
Thomas Weir: 42
Luke D'Anna: 42
Greg Donaldson: YES 42


try another

Hex A8     decimal ??   wait to be asked 
Emilly Taubman: sir if i do it a different way and still get the same answer can i do it my way
Greg Donaldson: 
   (yes thats fine Em...as long as I can see and understand what you are doing)
    
Greg Donaldson: 
David ?
Greg Donaldson: 
Thomas ?
Thomas Weir: 168
Greg Donaldson: 
Good



   16    1
    A    8

ie

    16   1
    10   8

= 10x16 +  8x1  = 168
Greg Donaldson: 
OK

Consider    110011001   convert to HEX please... wait
Greg Donaldson: 
Yuki ?
Yuki Igarashi: 199?
Greg Donaldson: 
Agree  Chris ?
Greg Donaldson: 
Yes or No    Chris ?    ??
Greg Donaldson: 
Here it is....


110011001

Break into groups of 4

      1   1001    1001

Calculate decimal for each group

    1   1001    1001
    1      9        9     Hex is  199 !

So see your menmtor and find out what the arrangements are  please ASAP  &#65532;
Greg Donaldson: OK Em ?
Emilly Taubman: yeah Ours is on Wedensday afterr tutor group &#65532;
David Turnbull: um, on the Assessment Task Sheet it says "Wednesday  April 4th "
Greg Donaldson: 
WOOPS...sorry folkes..I just realised my error

Test IS WEDNESDAY..not Thursday !!  sorry 
Greg Donaldson: Your mentors alreday have the test paper.....  sent today...you can check on that as well for me please.
Greg Donaldson: Any other questions about the test ?
Greg Donaldson: 
So....there will be NO chat next week.

THis week I want to do some revision....so I will be asking lots of relevant questions..HINT HINT  &#65532;
Greg Donaldson: 
Lets start.

How does RAD  get "rapid"     wait to be asked...
Greg Donaldson: 
Chris ?
Christopher Pike: whAT DOU MEAN B THE QUESTION???
Greg Donaldson: 
What is done in the RAD approach that enables it to be FAST=RAPID ?
Greg Donaldson: 
Daniel ?
Daniel Loth: it relies on libraries
Christopher Pike: no idia
Daniel Loth: for code
Greg Donaldson: Poor answer...

David ?
Greg Donaldson: 
Emilly ?
David Turnbull: um, isn't it like using already produced code, and a CASE tool?
Greg Donaldson: yes David...good
David Turnbull: &#65532;
Greg Donaldson: Em ?  anything to add ?
Greg Donaldson: 
OK...wait...
Emilly Taubman: no not really
Daniel Loth: question
Greg Donaldson: 
The RAD approach is fast because it makes use of "modules of code"...ie parts of existing solutions... so the developer does not have to rewrite the code....
Greg Donaldson: 
ie.   RAD    is used where a similar solution alreday exists...and parts can be adapted...
Daniel Loth: i've got a question
Greg Donaldson: 
So..RAD often applies in COMMON computing situations... eg database situiations.
Greg Donaldson: 
Yes Daniel ?
Daniel Loth: what was so poor about my answer?
Daniel Loth: i said libraries - a term used to define pre existing 'methods
Daniel Loth: functions or modules
Daniel Loth: i don't see the error
Greg Donaldson: 
I only saw...."for code"   either way I wanted a fuller answer....sorry Daniel.
Greg Donaldson: 
YES...libraries of code are where the "fragments" or modules of code are often found for RAD solutions

&#65532;
Thomas Weir: Has left the conversation.
&#65532;
Greg Donaldson: 
Yes   CASE tools may be used...but the essential concept is the use of existing modules...or parts of solutions
&#65532;
Thomas Weir: Has joined the conversation.
&#65532;
Greg Donaldson: 
OK..lets move on...
Greg Donaldson: 
What is a a PROTOTYPE  ?  wait...
Greg Donaldson: 
Luke ?
Luke D'Anna: a prototype is a peice of software that has been created and can either be further developed or discarded
Luke D'Anna: it is like a pre-solution
Greg Donaldson: 
Good Luke

Best definition is  "A prototype is a WORKING MODEL"
Greg Donaldson: 
NOTE: is it not a "mock up"  or a prtend version.

It MAY be the full solution...but usually is changed...

Greg Donaldson: 
So...what do we do with a prototype ... wait ... ?
Greg Donaldson: 
Steve ?
Greg Donaldson: Thomas ?
Steven Potiris: A prototype is either discarded and a new prototype is created based off it, or a prototype may fulfill the needs of the project and be accepted as the final result.
Greg Donaldson: Good but you are missing the key point Steve.
Greg Donaldson: 
What is the 1st thing we do with it ?

Thomas ?

Tirrell ?
Thomas Weir: i dont know
Tirrell Morris: we evaluate it and see if it meets the clients requirments
Greg Donaldson: &#65532;You all should know this !!!
Greg Donaldson: 
Geting closer...
Greg Donaldson: 
The point I wanted was...that the prototype was presnted to the client for feedback !!  you MUST say that !!!!
Greg Donaldson: 
If that is what is done...what is the key characteristic needed for prototyping to work well ?
Greg Donaldson: 
Yuki ?
Yuki Igarashi: what do you mean... do you mean like, budget and teamwork...?
Greg Donaldson: No...bit vague I guess

I was fishing for...

There must be good communication between clinet and devloper !
Greg Donaldson: 
What is the usual beginning characteristic oif the client in these situations ?

Anyone ?
Daniel Loth: they aren't sure on what exactly they need
Greg Donaldson: YES...!
Greg Donaldson: 
And that is why the developer makes a "sample"  to be able to say..."is this what you want" ?  what changes would yopu like made to this prototype ?

etc
Greg Donaldson: 
Ok...moving on

Give me some characteristics of all scenarios where a STRUCTURED APPROACH might be used 
Greg Donaldson: 
Wait...
Greg Donaldson: 
JUst one characteristic Chris ?
Christopher Pike: the user knows what they need
Greg Donaldson: 
Yes...but that would also be true of all of the 4 approaches except Prototyping


Daniel ?
Daniel Loth: the client needs a system that is as flawless, efficient and bug free as possible
Daniel Loth: ugh
Daniel Loth: rofl
Greg Donaldson: Excellent
Greg Donaldson: 
anything else ?  David ?
Greg Donaldson: anyone ?  (hint: time, $$, consequences)
Luke D'Anna: the client has to have a disposable budget generally
Emilly Taubman: they are large scale projectsa
Greg Donaldson: YEs...it will be expensive...so clinet must have the $$

Greg Donaldson: 
True...but that is a siude effect...its not esessential Em
Daniel Loth: they need a system that will be heavily relied on
Daniel Loth: where flaws can mean huge problems
Greg Donaldson: YES  that last line wasd IT !!
Greg Donaldson: (TIME !!!!!)   anyone ?
David Turnbull: it'd take ages wouldn't it? because the developer has to constantly consult the client?
Greg Donaldson: So ???
Greg Donaldson: Tell me abouit the client !
David Turnbull: they have to have plenty of time?
Tirrell Morris: the requirment need ot be established before u start because changes later on are costly and time consumine
Greg Donaldson: David Turnbull: they have to have plenty of time?

This is it !  the client must be ABLE to wait

So there would have to be a solution in place already to do the job in the meantime...
Greg Donaldson: 
OR the system is not yet working.   ie totally new organisation.
Greg Donaldson: 
OK...moving on....
Greg Donaldson: 
Remember ...the assignment where you were required to provide

1. A description of each approach
2. A scenario for each approach
3. A jsutification as to why that approach suits the scenario  ??


Greg Donaldson: WEll..

THAT assignment is IMPORTANT !!!!!   &#65532;
Greg Donaldson: 
Moving on....

question anyone ???
Greg Donaldson: 
So...now I am having to errect a Stop sign near my school

I will use a TOP DOWN approach

What would that mean ??       anyone ?
Emilly Taubman: that you wopuld have to break the process into more manageable steps?
Greg Donaldson: 
EXCELLENT !!
Greg Donaldson: 
THe Top Down approach...breaks a task int smaller parts...thgat can be done one at a time...
Greg Donaldson: 
Perhaps the sammler parts will be broken dopwn into smaller parts again...
Greg Donaldson: 
That will do there

Greg Donaldson: 
What is the largest decimal number that can be stores in a 3 bit binary format ?

wait,...
Greg Donaldson: 
Tirrell ??
Tirrell Morris: 7
Greg Donaldson: 
Good...tell us hpow or why please Luke 
Greg Donaldson: how
Luke D'Anna: each 1 represents a place value
Greg Donaldson: So ?
Luke D'Anna: the first 1 is 2^0
Luke D'Anna: the second 2^1
Greg Donaldson: (at the right)
Luke D'Anna: and third 2^3
Greg Donaldson: (middle 1)
Luke D'Anna: so 1+2+4 = 7
Greg Donaldson: 
Can you tell us ijn ONE send Luke ?

&#65532;
Luke D'Anna: the highest digit represent in binary is 111
2^2   2^1  2^0
1        1       1
4     + 2   +  1        =7
Greg Donaldson: 
A liitle like this

   Biggest binary is 111
   4   2  1
   1   1   1
   
Gives    1x4 +  1x2 + 1x1 = 7

Greg Donaldson: 
OK moving on

What is the   111 (octal) equivalent to in DEcimal ?   wait 
&#65532;
Emilly Taubman: Has joined the conversation.
&#65532;
Greg Donaldson: What is the   111 (octal) equivalent to in DEcimal ?   wait 

Steve ?
Steven Potiris: 7?
Greg Donaldson: NUP...OCTAL !!!
Greg Donaldson: 
THomas ?
Thomas Weir: 73?
Greg Donaldson: 
OK  show us how please Yuki 
Yuki Igarashi: 3
Greg Donaldson: 
Octal   111

   64     8    1
     1      1     1

= 1x64  +  1x8  +  1x1  =  73
Greg Donaldson: 
Next...
Greg Donaldson: 
Consider   hex  2A

what is the DECIMAL equivalent here ?   wait
Greg Donaldson: 
David ?
David Turnbull: 12 i think
Greg Donaldson: 
Nup

Tirrell ?

      
Greg Donaldson: Chris ?
Greg Donaldson: 
Ok...listen up....
Greg Donaldson: 
In hex what are the place value headings ?   anyone ?
Christopher Pike: me
Greg Donaldson: 
Yes Chris?
Greg Donaldson: just 2 or 3 will do
Greg Donaldson: anyone ?
Christopher Pike: just a sec
Emilly Taubman: 1,2,3,4,5,6,7,8,9, A,B,C,D,E,F             
Steven Potiris: 256 16 1
Luke D'Anna: 512   256   16   1
Emilly Taubman: haha im so dumb
Greg Donaldson: No Em  they are the DIGITS we use
Greg Donaldson: 
Yes Stev, Luke
Greg Donaldson: 
Ok so we have

    2A  ..
Christopher Pike: 4096, 256, 16, 1

Greg Donaldson: (Good Chris)


    16    1
     2     A
Greg Donaldson: 
ie

   16   1
    2   10      (A is 10)
Greg Donaldson: 

So we ahve

   2x16  + 10x1  =    ??? anyone ?
Yuki Igarashi: 42
Steven Potiris: 42
Emilly Taubman: 42
Thomas Weir: 42
Luke D'Anna: 42
Greg Donaldson: YES 42


try another

Hex A8     decimal ??   wait to be asked

Greg Donaldson: 
David ?
Greg Donaldson: 
Thomas ?
Thomas Weir: 168
Greg Donaldson: 
Good



   16    1
    A    8

ie

    16   1
    10   8

= 10x16 +  8x1  = 168
Greg Donaldson: 
OK

Consider    110011001   convert to HEX please... wait
Greg Donaldson: 
Yuki ?
Yuki Igarashi: 199?
Greg Donaldson: 
Agree  Chris ?
Greg Donaldson: 
Yes or No    Chris ?    ??
Greg Donaldson: 
Here it is....


110011001
