What is Waterfall Methodology?

Waterfall methodology is a project management approach where a project is completed in a series of steps, one after the other. Each step must be finished before moving on to the next. This method is like a waterfall, where water flows down in a straight line, making it easy to follow.

Key Features of Waterfall Methodology

1. Linear Process: The waterfall model follows a clear and structured path. This means that you move to the next phase only after finishing the current one.

2. Defined Phases: There are specific phases in the waterfall methodology:

   • Requirement Analysis: Gathering all the needs and requirements from stakeholders.
   • System Design: Planning how the project will work and look based on the requirements.
   • Implementation: Building the project according to the design plan.
   • Verification: Testing the project to ensure it meets the requirements.
   • Maintenance: Fixing any issues that arise after the project is completed.

3. Easy to Manage: Because each phase is distinct, it makes it simpler to manage and track progress. Teams can see what has been done and what is coming next.

4. Documentation Heavy: Waterfall methodology places a heavy emphasis on documentation. This means that every step is written down, making it easy to refer back to it.

Advantages of Waterfall Methodology

• Clarity: Since the process is linear and well-defined, it is easy for everyone involved to understand what to expect at each stage.

• Predictability: With clear phases and thorough documentation, it is easier to predict timelines, costs, and resources needed for the project.

• Less Ambiguity: The structured approach reduces confusion about roles and responsibilities. Everyone knows what they need to do and when.

When to Use Waterfall Methodology

Waterfall methodology works best in projects where requirements are clear and unlikely to change. It is often used in industries like construction, manufacturing, and software development, especially when the final product is well-defined at the start.
