Answer / hakim ali
The waterfall model the process goes to the next step after
completion of the previous step as first requirement then
design then coding then implementation then maintenance but
here is no end user feedback taken to consideration any
change in SRS will result to start work fro first step and
goes step by step again.
But in case of Spiral model for each and every step there
is testing for that step carry on simultaneously after
finishing that step so that it will easy to recover any
error and fix it there. In this model we don?t have to
start work from beginning

Answer / surendra
water fall model is a sequential model where each phase is done with the completion of the previous stage and the customer feed back or the end user feed back is taken after the implementation phase.
spiral model is an iterative and incremental model using the
prototyping technique.In this model customer involvement is done in each and every phase changes can be implemented in any stage of the process. And also time is not much wasted in the spiral model when compared to the water fall model.Testing and risk analysis is also easily handled in the spiral model this is somewhat difficult when compared with the earlier model.
The most advantage of the spiral model is TESTING is easily
implemented.
