The Fountain model is an improvement on the Waterfall model that allows for iteration and falling back to earlier steps in the project development process. It consists of the same sequential phases - analysis, requirements specification, design, coding, testing and integration, operation, and maintenance - but provides more flexibility by permitting iterations within and across phases. This makes the Fountain model better suited than Waterfall for projects where requirements are still evolving.

2. Fountain Model
The Fountain model is a logical
improvement to the Waterfall model. The
steps are still there, in the same
sequence, however at any step there can
be a fallback to an earlier step. Moving
through a number of steps and falling back
one or more steps, performed repeatedly, is
far more flexible than the Waterfall model.

4. Fountain Model Phases
 Analysis
 Requirements Specification
 Design
 Coding
 Testing and Integration
 Operation
 Maintenance or Evolution

5. Advantages
 many more interaction between design
and requirements
 supports iteration within phases
able to start the coding earlier

6. Disadvantages
•It may degraded into a code-a-bit test- a-
bit which requires frequent iterations and
refinement.

7. When to use?
• requirements keep on changing quite
frequently
• better use in the industry sectors
