2. In This Lecture You Will Learn:
About the Unified Software Development Process
How phases relate to workflows in an iterative life cycle
An approach to system development
Major activities in the development process

3. Unified Software Development Process
Developed by the team that created UML
Embodies best practice in system development
Adopts an iterative approach with four main phases
Different tasks are captured in a series of workflows

4. © 2010 Bennett, McRobb and Farmer
Best Practice
Iterative and incremental development
Component-based development
Requirements-driven development
Configurability
Architecture-centrism
Visual modelling techniques

Four Phases
Inception
Elaboration
Construction
Transition
© 2010 Bennett, McRobb and Farmer

6. Phases, Workflows and Iterations
Within each phase activities are grouped into workflows
The balance of effort spent in each workflow varies from phase to phase
Within phases there may be more than one iteration

8. Difference from Waterfall Life Cycle
In a waterfall life cycle project the phases and the workflows are linked together
In the Requirements phase, only Requirements workflow activities are carried out
All Requirements activity should be completed before work starts on Analysis
In an iterative life cycle project it is recognised that some Requirements work will be happening alongside Analysis work
