© Bennett, McRobb and Farmer In This Lecture You Will Learn: n About the Unified Software Develop- ment Process n How phases relate to workflows in an iterative life cycle n An approach to system development n Major activities in the development process

© Bennett, McRobb and Farmer Unified Software Development Process n Developed by the team that created UML n Embodies best practice in system development n Adopts an iterative approach with four main phases n Different tasks are captured in a series of workflows

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

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

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

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