![]() ![]() These steps are typically tracked through Gantt chart visualizations. It is made up of a series of steps that are completed in sequential order within the software development life cycle (SDLC). However, it is generally less effective (and even detrimental) in situations where requirements are not well-understood, where there are many unknowns, or where changes are likely to occur during the development process, since waterfall isn’t inherently flexible or adaptable to unique situations. Waterfall methodology, also known as the linear sequential lifecycle model, is defined by its linear, structured approach to project management. A good example is operating system development. The Waterfall model is the earliest SDLC approach that was used for software development. Thus, there is heavy focus on getting everything right in the early stages before costly mistakes are made.ĭespite some obvious drawbacks, a waterfall model can still be useful in situations where requirements are well-defined and knowable upfront and design isn’t likely to change, because of these known properties. A key assumption of waterfall is that the requirements and design will not change significantly during the development process. In the waterfall analogy, this would be like trying to climb back up the waterfall. Once a phase is completed, it is typically not revisited without starting the entire process over again because of the fairly rigid, linear process flow that lends itself to building heavy dependencies into requirements. The general process includes the following phases:Īs mentioned above, each phase is completed before the next phase begins. It is a sequential, linear approach to software development where each phase of the development process occurs in a specific order and is completed before moving on to the next phase. Waterfall is a software development methodology and was the primary methodology used by software teams and companies until the mid 2000s when it largely fell out of favor of Agile methodologies. ![]()
