How can you determine project scope using the Waterfall methodology?

1 What is the Waterfall methodology?

The Waterfall methodology is one of the oldest and most widely used project management methodologies, especially in software development and engineering projects. It is based on the idea that each phase of the project must be completed and verified before moving on to the next one, and that changes or revisions are minimized or avoided once the project scope is defined. The Waterfall methodology typically consists of six phases: requirements analysis, design, implementation, testing, deployment, and maintenance.

3 How to validate project scope in the Waterfall methodology?

The second phase of the Waterfall methodology, design, is where the project scope is validated. In this phase, you need to translate the requirements into a logical and physical design that describes how the project will be executed. You need to create and review various diagrams, models, prototypes, mockups, and architectures that illustrate the structure, layout, interface, and components of the project. You also need to define the standards, methods, tools, and techniques that will be used in the project. The output of this phase is a design document that confirms and approves the project scope.

4 How to control project scope in the Waterfall methodology?

The remaining phases of the Waterfall methodology, implementation, testing, deployment, and maintenance, are where the project scope is controlled. In these phases, you need to monitor and measure the progress and performance of the project against the scope baseline and the design document. You need to ensure that the project deliverables meet the quality standards and the acceptance criteria. You also need to manage any changes or deviations from the original project scope, and document and communicate them to the relevant stakeholders. The output of these phases is a completed and verified project that meets the scope expectations.
