Sawtooth model - kubapeter/portfolio GitHub Wiki

The Sawtooth model is a linear process model, in which the client is involved to review intermediate prototypes of the product during the process.

As the process proceeds linearly, there are phases that involve the client in the top section of the diagram and phases that involve only the development team in the bottom section, which creates a jagged “sawtooth” pattern.

Pros and cons

Pros:

  • easy to understand
  • clearly defines deliverables and milestones
  • emphasizes the importance of analysis before design, and design before implementation

Cons:

  • not very adaptable to change: there is a limit toincorporating anything more than incremental changes
