Waterfall methodology is a project management approach that emphasises a sequential, linear process for developing software or other products. It is named after the waterfall model, which depicts a series of stages that flow sequentially downwards, with each stage feeding into the next.

In the waterfall model, the process starts with a requirements gathering stage, where the project team works closely with the client or stakeholders to define the requirements for the software or product. Once the requirements are finalised, the design phase begins, where the team creates detailed specifications for the software or product.

After the design phase, the development phase begins, where the team starts coding the software or building the product. Once the coding is completed, the testing phase begins, where the team tests the software or product to ensure that it meets the requirements and specifications. Finally, the software or product is deployed to the end-users in the implementation phase.

Overall, the waterfall methodology can be a useful approach for software development or product development projects that have well-defined requirements and a clear scope. However, it may not be the best choice for projects that require greater flexibility or adaptability, or where requirements are likely to change significantly over the course of the project.

The Waterfall approach is interesting for smaller projects (WordPress).
