You will also make a project lifecycle plan and plan your sprints if you are a software engineering team using some scrum tools. The idea is to have a clear set of deliverables. Here you can also write a project charter and a product backlog of what the end product will do. It is the time to create an upfront project requirements document and decide what metrics to use to measure project success. The first phase of the waterfall methodology is the gathering phase. We’ll shed some light on that discrepancy afterwards.Ħ. Maintenance 1. Sometimes you’ll see that there are only 5 given. While the exact number ranges, for this article, we will explain the 6 waterfall project management steps or phases. What are the 6 waterfall project management phases Its emphasis on visualizing the process two-dimensionally and achieving focus is also quite different from the waterfall approach. We could also ask: what is kanban methodology doing differently in relation to the waterfall approach? Kanban, developed just a bit earlier, in the late 1940s in postwar Japan, focused on process improvement, based on lean values and lean thinking. Waterfall is much more linear compared to lean PM, as the latter de-emphasizes hierarchy, and aims for smaller inventories and regular deliverables. The traditional waterfall project management approach perhaps goes back to 1985 when the US Department of Defense developed certain guides and standards that any outside contracting software developers would have to use.īecause of the longevity of the method, it’s key to understanding project management basics, as its tried-and-true, straightforward phase-based model can be compared to other canonical techniques.įor example, waterfall can be contrasted with lean project management conventions, which also date back to the 1950s and the flexible, “just in time” Toyota method. However, the term “waterfall” was not used yet, not until the mid-70s.

The history of the project management waterfall model goes back to 1956 and the Symposium on Advanced Programming Methods for Digital Computers. How & when was the waterfall approach to project management created? In the end, the waterfall model is appropriate for planned project phases for continued project progress throughout the lifecycle. You might say that the critical path method is the opposite of the agile methodology, and the waterfall is between them, though probably closer to the critical path.įinally, if your team wants to use a WBS, or work breakdown structure, then doing so while you use waterfall techniques is also appropriate, as it would be in agile project management too. the critical path method, the waterfall model is more useful and appropriate when there are fewer constraints in terms of timelines and event sequences. When it comes to comparing other PM systems, like the waterfall vs. By contrast, agile teams can work more independently at their own pace. The waterfall project methodology is also useful for when you have a project that has strong task dependencies and task groups, which mean that one or some part of the project’s workflow cannot be initiated before another or all other project workflows have been completed. What does that mean? Basically, when it comes to waterfall vs agile project management, the key difference is that there is more upfront planning in the waterfall method for the entire project lifecycle than there is for agile teams. Waterfall PM is appropriate when an agile approach is not. When is the waterfall pm methodology appropriate? On the other hand, it has some relative weaknesses in areas of scheduling and task dependencies. It’s one project management methodology among many, but one that’s particularly adept for large teams thanks to its clear planning stages. This is what is meant by the project management waterfall methodology. What’s more, the waterfall approach stresses that everyone's tasks be grouped in stages, and that all tasks per stage must be completed before any tasks in the next stage can begin. The waterfall model refers to a project management style and method that stresses the linear and sequential ordering of a project through several stages. Let’s begin with a waterfall project management definition.
