The Waterfall project management methodology is one of the most traditional approaches to managing projects. At Commercial Networks, we often see businesses use it for projects where structure, predictability, and clear deliverables are essential. Unlike flexible methods such AS Agile, Waterfall follows a sequential process where each phase must be completed before moving on to the next.
The Waterfall Project Management Methodology Explained
In Waterfall, projects are delivered in distinct phases: requirements, design, implementation, testing, and deployment. This linear process ensures that every stage is thoroughly planned and documented, reducing ambiguity and giving stakeholders a clear picture of progress.
Because requirements are defined at the beginning, Waterfall is particularly effective for industries such AS construction, manufacturing, or compliance-driven IT projects where changes mid-project would be costly or impractical.
The methodology is also valued for its emphasis on documentation, which helps maintain transparency and supports smooth handovers between teams. However, this comes at the expense of flexibility, adapting to change once a project has started can be challenging.
Project Workflow in Waterfall
Every project workflow within Waterfall follows a fixed sequence:
- Requirements Gathering – Scope, objectives, and deliverables are documented.
- Design – The architecture and specifications are created.
- Implementation – Developers or teams build according to the design.
- Testing – Rigorous checks ensure quality before deployment.
- Deployment & Maintenance – The finished product is delivered and supported.
This structured approach makes it easy to track milestones, but it also means errors at the start can cascade through the project. That’s why thorough planning is critical to Waterfall’s success.

Agile vs Waterfall
When comparing Agile vs Waterfall, the key difference lies in flexibility. Agile is iterative, allowing teams to adapt and respond to change throughout the project. Waterfall, in contrast, is sequential and best suited to projects with stable requirements.
Agile encourages continuous feedback, while Waterfall typically reserves feedback until the testing phase. Businesses must choose based on their needs: Waterfall for predictability and compliance, Agile for adaptability and speed. Some organisations even adopt hybrid models to get the best of both.
Final Thoughts
The Waterfall project management methodology remains a reliable choice for organisations that need structure, clear documentation, and predictable delivery. While it may lack the adaptability of Agile, it excels in projects with fixed requirements and strict regulations.
