A vatnsfallamódel, often translated as a "waterfall model," is a sequential software development process. It represents a project's lifecycle as a series of distinct phases, each flowing into the next like a waterfall. The typical stages include requirements gathering, design, implementation, testing, deployment, and maintenance.

Each phase must be completed and signed off before the next phase can begin. This structured approach emphasizes thorough documentation and planning at each step. The waterfall model is known for its simplicity and ease of management, making it suitable for projects with well-defined and stable requirements.

However, its rigid nature is a significant drawback. Changes to requirements late in the development cycle can be costly and difficult to implement. There is little room for iteration or feedback until the testing phase, which can lead to a product that doesn't fully meet user needs. Consequently, the waterfall model is less suited for complex or rapidly evolving projects where flexibility is crucial. Its application is often seen in industries where strict regulatory compliance necessitates a highly structured and documented process.
