Final answer:
The waterfall model in website development requires completion of one phase before starting the next, contrasting with agile methods that work well in uncertain environments.
Explanation:
Waterfall model is the website development model that requires a new phase to start only when its previous phase is completed. In this model, each phase must be completed before the next one begins, ensuring a structured and sequential process.
For example, in a waterfall model, the design phase must be finished before development starts. This approach is suitable for projects with well-defined goals and limited uncertainty, unlike agile methods that thrive in more uncertain environments.
