Have you ever asked yourself, "What's the most straightforward way to manage a project?”

The answer is, “Waterfall Project Management.”

The Waterfall methodology—also known as the traditional approach—is a sequential development process, which means that each phase must be complete before the next phase begins.

Waterfall gets its name because each phase of the project cascades into the next.

This video provides a simple overview.

How Does Waterfall Work?

Overview of Waterfall

  • At the beginning of the project, you create a detailed project plan that includes all the requirements.

  • You then proceed through a series of clearly defined phasesuntil you’ve fully executed on the plan.

  • Tasks and phases are completed in a linear, sequential manner, which means the output of each phase acts as the input to the next phase.

  • Each participant has a clearly defined role and none of the phases or goals are expected to change.

 

The Five Phases Of Waterfall

  1. Requirements: This is where you gather and analyze all the information about the project and identify the different functions and features you need.

  2. Design: Once you understand the requirements, you design the project workflow, architecture and system.

  3. Implementation: In this phase you start the actual development, making sure you use your requirements and specifications.

  4. Verification: Once you complete coding, you start testing. This is to ensure that there are no errors and the product meets its requirements.

  5. Maintenance: Finally, when you deploy the project, you provide subsequent support and maintenance to make sure the product works.
