Q. How does the risk factor affect the spiral model of software development?
Ans: Risk Analysis phase is the most vital part of Spiral Model. In this phase all probable (and available) alternatives which can help in developing a cost effective project are analyzed and strategies are decided to use them. This phase has been added particularly in order to identify and resolve all the possible risks in the project development. If risks point to any kind of uncertainty in requirements prototyping may be used to proceed with the available data and find out possible solution in order to deal with the potential changes in the requirements.
