The customer will review the product to see that it meets the requirements set out at the start of the project. The completed product is released to the customer during the verification phase once it has been tested for errors. However, the team may have to revert to the design phase if significant changes are necessary during implementation. ![]() Implementation is usually the shortest waterfall phase since all of the research and design should be finished at this point. In the implementation phase, programmers use the requirements and specs from the previous phase to develop code. The second is the physical design subphase, where those ideas get converted into actual specifications via the team’s hardware and software technologies of choice. The first is the logical design subphase, where solutions are thought up and theorized, and the project’s scope, general traffic flow, and integration points are discussed. The process of crafting a solution is divided into a pair of subphases. This solution can include layouts, scenarios, data models, etc. Waterfall’s design phase is where software developers come up with a technical solution to the challenges presented by the product requirements. To ensure accuracy, all written requirements are often detailed in a single document that describes each project phase to include things like:Īfter the first phase is complete, correspondence with customers will not resume (in theory) until the product is finished. Once those requirements are gathered, the subsequent phases in the overall sequence can be planned accurately. RequirementsĪ project cannot succeed using the waterfall methodology without collecting and fully understanding customer and stakeholder requirements in the first phase. ![]() One phase cannot begin until the previous one is completed. We list the phases below as initially described by waterfall’s founder, Winston W. Waterfall has five standard phases or stages, which may vary in name depending on where you look. Unlike the Agile method, they do not have to provide frequent status reports. Team members following the waterfall method typically work independently. They are often self-contained unless specific integrations are needed. Since it takes the linear approach, waterfall does not require individual execution teams to collaborate constantly. The waterfall method works in a chronological manner that relies on fixed requirements, dates, and outcomes.

Everything must be documented in advance, including user stories, interface, features, etc., so accurate time estimates can be produced and a predictable release date can be achieved. ![]() Unlike the Agile methodology that lets teams easily adapt on the go as obstacles arise, changing course is much harder with the waterfall method. This is because the method’s success depends heavily on the front end due to its linear nature. Most of the work in the waterfall method is done on the front end, especially as it pertains to research. For instance, software engineering projects are often managed using the waterfall software development life cycle (SDLC). Waterfall is structured, thorough, and has been used for several years because it produces results for organizations in industries like software development, IT, and construction. The waterfall method starts with gathering customer and stakeholder requests at the outset of the project so a sequential project plan can be created to adhere to those requirements. It is so named since it is a sequential software development process that flows in a downward motion like a waterfall, with each project phase cascading into the next. The waterfall methodology, or model, is a linear approach to project management that requires each phase to be completed before moving on to the next.

We will discuss what the waterfall software development methodology is, its different phases, and more so you can see how it could help your team meet its goals. Many software developers use the waterfall methodology to manage their projects.
