The waterfall model is a sequential design process, used in software development processes, in which progress is seen as flowing steadily downwards (like a waterfall) through a series of phases (stages).
Phases
Phases of the waterfall mode:
- Conception
- Initiation
- Analysis
- Design
- Construction
- Testing
- Production/implementation
- Maintenance.
Origin
The waterfall development model originates in the manufacturing and construction industries: highly structured physical environments in which after-the-fact changes are prohibitively costly, if not impossible.
Since no formal software development methodologies existed at the time, this hardware-oriented model was simply adapted for software development.
Agile software development
Agile software development is intended to improve upon the Waterfall model.
