Logical progression of steps used throughout the life cycle
Stages of falling water
Each phase must be completed before the next begins, with little to no overlap
- Clear, step by step nature
- Progress flows in one direction
- Outputs from one stage become inputs for next
Advantages and disadvantages
| Advantages | Disadvantages |
|---|---|
| Simple and easy to understand | Inflexible to change |
| Clear milestones and deliverables | High risk and uncertainty (problems discovered later) |
| Good when requirements are unlikely to change | Testing only after development |
| Easier to manage (rigid structure and documentation) | Not suitable for complex or evolving projects |
Scale and types of developments
- Best projects with clearly defined requirements
- Used in projects for embedded systems, military, etc where rigorous documentation and predictability is important
- Not well suitable for agile environments, iterative development, modern web apps (user needs evolve rapidly)
