A survey of Boehm's work on the spiral models and COCOMO II - Towards software development process quality improvement
Successful engineering and evaluation of complex software depends on successfully completing all the stages of the Software Development Life Cycle. There have been many models which illustrate the stages Software Engineers have to go through to produce software. This paper investigates one of these-The Spiral Model (Sommerville 1997) with particular reference to recent enhancements to it, examines the interaction of COCOMO II (1998) within the WinWin framework, and reports on a case study using the WinWin Spiral Model (Boehm et al. 1998) to develop software.
