In these models, some of the steps from the original waterfall model were broken down or merged into other phases. However, variations in the process were developed over the years, and some of these models have 5 or 7 phases. The Phases of Waterfall Project Management MethodologyĪs described by Royce, the original waterfall model defined 6 steps or phases. As a result, changes to the project phases or goals are typically discouraged. Any change to the project parameters usually means a complete or partial rework of the previous phases, making it more complicated and more expensive to change course once the project is underway. As most of the research and planning is done early, the estimates for each phase are more accurate, resulting in more predictable outcomes. This method’s success or failure depends on the effort given during the initial phases. A typical waterfall project management model can be broadly divided into the phases seen below. Team members are given clearly defined roles and are encouraged to work linearly toward the goal. ![]() One of the most traditional project management methodologies, the waterfall model is particularly useful in projects that follow a single timeline with highly detailed plans. The original model proposed by Royce for software development is shown below. However, no single person is formally credited for the creation of the waterfall project management methodology. Royce, an American computer scientist, in 1970. The first formal diagram of the waterfall process is typically attributed to an article written by Winston W. As such, through the different phases of the project, the process flows in only one direction, similar to a waterfall. The waterfall project management model takes a linear approach in which project activities are broken down into sequential steps or phases, and each phase is entirely dependent on the deliverables of the previous phase. ![]() What Is the Waterfall Project Management Methodology? ![]()
