It is a
type of incremental model. In RAD model the components or functions are
developed in parallel as if they were mini projects. The developments are time
boxed, delivered and then assembled into a working prototype. This can
quickly give the customer something to see and use and to provide feedback
regarding the delivery and their requirements.
Advantages
of the RAD model:
- Reduced development time.
- Increases reusability of components
- Quick initial reviews occur
- Encourages customer feedback
- Integration from very beginning solves a lot of integration issues .
·
Depends
on strong team and individual performances for identifying business
requirements.
·
Only
system that can be modularized can be built using RAD
·
Requires
highly skilled developers/designers.
·
High
dependency on modeling skills
. Inapplicable to
cheaper projects as cost of modeling and automated code generation is very
high.
