Phases of systems development life cycle (SDLC)
SDLC consists of 4 phases:
- Planning
- Analysis
- Design
- Implementation
Each phase is composed of steps that rely on techniques that produce deliverables.

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

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)
