Which characteristic describes the Waterfall Model in project management?

The Waterfall Model is characterized by a linear and sequential approach to project management, where each phase must be completed before the next one begins. This means that tasks are distinctly separated and follow a specific order: requirements gathering, design, implementation, testing, deployment, and maintenance. Each phase serves as a foundation for the next, necessitating the completion of one phase before moving on to the next, which emphasizes clear project milestones and deliverables.

This sequential nature of the Waterfall Model helps in planning and managing the project, as stakeholders can gauge progress at defined stages. It contrasts with more iterative methodologies, where phases overlap or cycle back based on continuous feedback and collaboration. Therefore, the defining characteristic of the Waterfall Model is indeed the performance of separate tasks in a defined order, reinforcing the importance of a structured progression through the project lifecycle.
