Answer Posted / varsha b
In Waterfall model each step is distinct.After completion
of step one can move to next step and once you are through
from one step you cant move back.Hence waterfall model is
useful only those projects where requirements are well
understood and no chang in requirements is needed.
In spiral model we dont define every thing in detail at
very beginning.we start with basic functionality and work
them out.we take client's feedback.If developed
functionalities is as per clients requirement then we move
on to next step.Spiral model is useful when requirements
are changing.
