2. Prototyping

1.

How the client explains to
the developer what he
wants
How the developer
understands it
Documentation
How the developer
makes the prototype
Testing
How the developer
do program
What the client
needed

2. To ensure that the design is what the customer wants, the customer must see an early implementation of the proposed system. 

To ensure that the design is what
the customer wants, the customer

How is the early version of project
called?

3. 11.2B Designing a new system Prototyping

4. Learning objectives

11.2.2.4 discuss the advantages and disadvantages of
using prototypes in developing solutions
11.2.2.5 discuss the use of prototypes based on a specific
example
11.2.2.6 develop a prototype for a new system

5. Criteria assessment

• Knows what a prototype is
• Distinguishes the advantages and disadvantages
of using prototypes
• Develop a prototype for a new system

6.

A prototype represents some aspect of the full system for instance a mock-up of the graphical user interface.
Consider a prototype GUI, where users click on
command buttons and see its effect. That button is not
actually connected to a real system but is programmed
by the developer to act as if it was. The command
action is simulated with dummy data.
Now the user is beginning to see how the real system
will work before the developer spends even more time
on it.
So a prototype is NOT a fully working system but it does
provide an opportunity for the user to give feedback and
suggestions for improvements. This may happen again
and again until the full details are agreed between
developer and user. Therefore prototyping is an
'iterative' process.
Any changes required are fed back to the developer and
the Requirements Document is also updated every time
a change is needed.
It is much cheaper to build a prototype and iron out the
problems rather than go straight into the development of
the main system and then find out there are problems.

• Discuss the sufficiency of
your prototype for
development?
• What else can you add?

DID NOT UNDERSTAND! HELP ME!
• I need more explanation​
• Well, everything is clear
What are the criterias for an effective prototype?
