Iterative and incremental development involves
repeating a set of activities (cyclic), evaluating output and
incrementing. Output of an increment may not necessarily result in
an increment. Iteration will help to improve the process. Once the
process is improved as expected, an increment is done. Iterative
& incremental development helps to determine flaws in the
Procedure begins with initial planning of
requirements, followed by Analysis and Design, Implementation,
Testing, evaluation and deployment. A project control list is used
for iteration process which describes all the tasks. This list is
revised constantly on analysis. If the outcome of any task is not
satisfactory, redesign or reimplementation is done else an increment
is done. The cycle should easily be adaptable to modifications. As
the iterations increase the system can adapt modifications
