![]() Verification or testingīefore a product can be released to customers, testing needs to be done to ensure the product has no errors and all of the requirements have been completed, ensuring a good user experience with the software. If significant changes are required during this stage, this may mean going back to the design phase. In this phase, programmers code applications based on project requirements and specifications, with some testing and implementation taking place as well. This might be the shortest phase of the Waterfall process, because painstaking research and design have already been done. ![]() Once the design is complete, technical implementation starts. Once this is complete, it is transformed into a physical design using specific hardware and software technologies. First, a higher-level or logical design is created that describes the purpose and scope of the project, the general traffic flow of each component, and the integration points. Here, software developers design a technical solution to the problems set out by the product requirements, including scenarios, layouts, and data models. Written requirements, usually contained in a single document, are used to describe each stage of the project, including the costs, assumptions, risks, dependencies, success metrics, and timelines for completion. The project manager does their best to get a detailed understanding of the project sponsor’s requirements. The Waterfall methodology depends on the belief that all project requirements can be gathered and understood upfront. Using a software development project as an example, the Waterfall process usually includes stages that look like this: Requirements ![]() Usually, one phase doesn’t begin until the previous one is finished. Team members also tend to work independently and aren’t expected to provide status reports as often as with the Agile approach. With this method, the individual execution teams aren’t required to be in constant communication and, unless specific integrations are required, are usually self-contained. The Waterfall methodology follows a chronological process and works based on fixed dates, requirements, and outcomes.

It is said that the Waterfall methodology follows the adage to “measure twice, cut once.” The success of the Waterfall method depends on the amount and quality of the work done on the front end, documenting everything in advance, including the user interface, user stories, and all the features’ variations and outcomes. The Waterfall methodology-also known as the Waterfall model-is a sequential development process that flows like a waterfall through all phases of a project (analysis, design, development, and testing, for example), with each phase completely wrapping up before the next phase begins.
