- Generic process models
- Waterfall
- Evolutionary development
- Formal transformation
- Integration from reusable components.
The waterfall model is also known as the classic life cycle or linear sequential model. Pure Waterfall, Spiral, Modified Waterfall, Evolutionary Prototyping, Code-and-Fix, Staged Delivery, Evolutionary Delivery, Design-to-Schedule, Design-to-Tools, Off-the-Shelf are some other types of software project life cycle.
