Explain the software life cycle model that incorporates risk factor.
The problem with traditional software process models is that they do not deal adequately with the uncertainty, which is inherent to software projects. Significant software projects failed because project risks were neglected and nobody was ready when something unforeseen happened. Barry Boehm recognized this and tried to incorporate the " project risk" factor into a life cycle model. The results is the spiral model, which was presented in 1986 BOEH86 Every loop of the spiral from X-axis clockwise by 3600 represents one phase. Single phase is split roughly into four sectors of major activities.
