When it comes to managing projects, knowing which methodology to use is crucial. By thoroughly understanding each project management model , you will be able to choose one that allows you to reduce costs, minimize errors, and maximize efficiency .
The waterfall methodology was first defined by American computer scientist Winston W. Royce in 1970 to detail a method for managing software development projects. Since then, its use has been adapted to a number of key industries, from construction to information technology.
In this article, we will introduce the waterfall methodology, explain its main uses, benefits and drawbacks, and then compare it to some of the main project management models.

What is the waterfall methodology ?
This methodology seeks to break down each part of a project overseas chinese in europe data into clearly defined sequential phases. The word “waterfall” refers to the downward movement of a waterfall, as each phase of the project must be completed in order without going back.
Think of a series of wells separated by waterfalls. The wells represent each phase in the time sequence of project management, from planning, then development, to launch. Water cannot reach the next well until it overflows and continues on to the next. Similarly, when using the waterfall methodology, it will not be possible to move on to the next phase until the current phase is 100% complete.
The waterfall methodology has three basic principles:
Strict one-way structure: When using the waterfall method, the project is divided into discrete phases, which must be completed in order. There is no way to go back or change course if something unexpected happens. If this were the case, you would have to start over from the first stage.
Little or no stakeholder involvement after the first stage: Due to the waterfall structure of the process, all interactions with stakeholders in the first stage must be documented. Then, due to the rigidity of its structure, there is no way to implement changes and communication with stakeholders is interrupted.
Detailed documentation of the entire process upfront: To overcome some of the limitations of the waterfall method, each stage needs to be documented in detail upfront. Because customer feedback cannot be received during the process, all requirements should be documented before the project starts.
The waterfall method has been popular in the construction industry, as activities must occur in a strict order. In construction, once a stage is completed, it is almost impossible to reverse it. For example, there is no way to “pour” concrete. Likewise, brick laying cannot begin until the concrete foundation has solidified.
