3 1 prescriptive models

3.1 Prescriptive Models

  • Prescriptive process models advocate an orderly approach to software engineering

  • If prescriptive process models strive for structure and order, are they inappropriate for a software world that thrives on change?

  • If we reject traditional prescriptive process models and replace them with something less structured do we make it impossible to achieve coordination and coherence in software work?


3 2 the waterfall model

3.2 The Waterfall Model

  • Is the waterfall model obsolete?


3 3 the incremental model

3.3 The Incremental Model

  • What is an “increment”?

  • When is it appropriate to apply the incremental model?


3 3 the rad model

3.3 The RAD Model

  • When is it appropriate/inappropriate to apply the RAD model?


3 4 evolutionary models prototyping

3.4 Evolutionary Models: Prototyping

  • How are evolutionary models different from incremental models?

3 4 evolutionary models the spiral

3.4 Evolutionary Models: The Spiral

  • How does the spiral model differ from prototyping?

  • What is the role of risk analysis in the spiral model?


3 4 evolutionary models concurrent

3.4 Evolutionary Models: Concurrent

  • I don’t like this one so don’t spend too much time reading about it.


3 5 specialized process models

3.5 Specialized Process Models

  • Component based development—the process to apply when reuse is a development objective

  • Formal methods—emphasizes the mathematical specification of requirements

  • AOSD—provides a process and methodological approach for defining, specifying, designing, and constructing aspects

  • What are the primary advantages of the component-based process model?
