Methodologies for Sdlc University of Nottingham 4/13/2017 Methodologies for Sdlc Structured Design – formal step-by-step approach - Waterfall development – sequential process - Parallel Development – division into subproject Rapid Application Development – focuses on quick development - Phase development – versions-based process - Prototyping – performs phases concurrently and repeatedly - Throwaway Prototyping – uses disposable design prototypes Agile - eliminates documentation overhead and modelling - Extreme Programming - Crystal, Adaptive Software, Scrum etc Software Project Management Maria Petridou Maria Petridou

University of Nottingham 4/13/2017 Exercise Suppose you are a project manager using the waterfall development methodology on a larger and complex project. Your manager has just read the latest article in Computerworld that advocates replacing the waterfall methodology with prototyping and comes to your office requesting you to switch. What do you say? Taken from (Dennis&Wixom, page 23). Reading: (Dennis&Wixom, chapter 1) and (Kendall&Kendall, chapter 1) Software Project Management Maria Petridou Maria Petridou
