## The Software Life Cycle

- The spiral model, proposed by Barry Boehm in 1988, breaks the development process into multiple phases.
- Early phases focus on the construction of prototypes - small systems that show some aspects of the final system.
- Because prototypes model only part of a system they can be implemented quickly.
- Lessons learned from the development of one prototype can be applied to the next iteration of the spiral.
