WATERFALL MODEL

A classic model of project management is the waterfall model. It is often used in companies with hierarchical structures.

what is the waterfall model?

Here, the project is divided into several stages or phases, which build on each other and are processed one after the other. You should run through ever phase only once and the results of the previous phase are used as a preliminary assumption in the subsequent phase. Also you should gather Requirements in advance. When the customer and developer agree on what to implement, the planning phase begins. Each phase starts with the end of the previous one. For example: testers during coding create test scripts from requirements documentation.

A typical flow is:

• Analysis
• Design
• implementation
• Test
• Deployment

So, once you completed a phase, you should not reverse that decision.
