What are characteristics of the waterfall development methodology?

The waterfall development methodology is characterized by its linear and sequential approach to software development. This means that the project moves through a series of defined phases in a specific order, typically starting with requirements gathering, followed by design, implementation, testing, deployment, and maintenance. Each phase must be completed before moving on to the next one, creating a structured framework where progress flows in one direction, like a waterfall.

This methodology is well-suited for projects where requirements are well understood upfront, making it easier to manage and predict the outcomes at each stage of the development process. Since each phase is distinct, it provides clear documentation and benchmarks for measuring progress and ensures that all aspects are thoroughly vetted before moving on.

In contrast, other methodologies that are more iterative and incremental focus on flexibility and continuous delivery of smaller features, which is not inherent to the waterfall approach. The waterfall model's emphasis on a defined sequence also limits opportunities for deep knowledge sharing across roles, as the methodology typically involves specialization that aligns with specific phases or functions. Additionally, changes during the development process can be challenging and costly in a waterfall model, making it less adaptable to evolving requirements.
