What is Waterfall project management methodology?
The Waterfall project management methodology is a linear technique that’s more commonly used for software development projects.
The name originates from the flow of the waterfall, which is the same as the stages of this model due to its downward motion.
Since its creation in 1970, it has been recognized as one of the world’s most used project management methods.
Applying the Waterfall methodology, you must complete every project phase for you to move to the next one. To invest in this model, you would have stages such as design, testing, maintenance, implementation, deployment, and requirements.
There are four essential principles to establish the Waterfall project management methodology:
- Separation of every phase: When structuring every phase, you must define and separate one from the other, categorizing them as you’ve seen above.
- Plan to the last detail: A full briefing with every detail is the key to bringing success to your project within the Waterfall methodology.
- Linear breakthrough: It’s mandatory to complete every phase before going to the next. You cannot go through to the next phase and come back to the previous one. You’ll significantly damage your project if you don’t respect the natural flow.
- Keep everything documented: While working on every phase, ensure you leave every type of documentation to support the team in the future. It’s also an excellent system to demonstrate to everyone who’s not as involved but needs to be updated, such as the stakeholders.

What are the 6 stages of the Waterfall project management methodology?
The 6 stages of the Waterfall project management methodology are requirements, design, implementation, testing, delivery, and maintenance. Let’s have a look at each one.
1. Requirements
This is the phase where the project manager establishes the list of requirements and documentation needed to complete the project and the phase itself.
Documentation such as interviews, briefings, a selection of rules, or even bullet points are some of the things that will be in your favor if you have them. Once you have everything ready, you can pass to the next step.
A project management checklist is a document that can be really helpful in this stage.
2. Design
After completing the right set of requirements and following documentation, it’s time to design the workflow model for the rest of the project.
With the help of the documents established in the first stage, you can see what you need to do to design the full system. This is where the team begins to define the required programming, along with the hardware and software equipment that will help pave the way through.

3. Implementation
This is where the real work comes to take its place.
Your team starts to move and take care of the tasks at hand. From coding and programming with the documentation and design that was provided previously, they can create in this stage.
The goal is to achieve a significant and final product delivery.
4. Testing
This stage ensures that the previous ones were right through the testing method.
After designing and implementing the requirements that were once established, now’s the time to see if everything is according to plan.
It’s normal to find some inconsistencies, but if they’re more severe than you expected, you may need to start this method immediately.
5. Delivery of the product
At this point, everything’s turning out great, and you can let your product out in the world. Since the product is finished, this stage is the opportunity to release your final and tested product.

6. Maintenance
After delivering the final product, there’s one last stage to follow, which recalls the maintenance of what you just delivered. Because there’s a potential for possible issues, the team works for the resolution of them to keep the product in the best quality possible.
As it was said in the testing phase, if some problems are not easy to fix, you may need to go back to square one.

- Without the involvement of the stakeholders, you won’t have recurring requests;
- Any new developers that may enter during any stage of the method will quickly be up to speed due to the existence of a clear briefing;
- The analysis of the project’s progress is even clearer;
- It’s possible to almost factually estimate the budget and timing for every stage, as well as for the project as a whole;

Disadvantages of the Waterfall project management method
Although this project management technique stands as a straightforward tool, it shares some disadvantages that you should look out for:
- Planning way ahead than you should before starting the journey can hurt your project:

- Stakeholders will share difficulty in elaborating a full briefing without having the opportunity to change some aspects throughout;
- Clients are not as involved as they would have been in any other model;
- If something delays any part of the project’s stages, the rest will also be delayed, affecting the final delivery.
Who can use the Waterfall project management methodology
This method is most used by engineers and project managers, who take advantage of this model to develop their projects.
It’s a perfect tool for a project with everything defined in detail. There must be a complete and clear briefing, so you can proceed with this specific methodology.
