Final answer:
Waterfall and Agile are two different project management methodologies. Both include phases and tasks, but the number of common phases and tasks vary. Thus, the correct option is d. All
Step-by-step explanation:
Waterfall and Agile are two different project management methodologies used in software development. While they both involve phases and tasks, the number of common phases and tasks varies. The Waterfall methodology follows a linear and sequential approach with distinct phases such as requirements gathering, design, development, testing, and deployment. Each phase must be completed before moving on to the next.
The Agile methodology, on the other hand, is iterative and incremental, focusing on flexibility and collaboration. It typically includes phases such as planning, analysis, design, development, testing, and deployment, but the specific tasks and their order can vary depending on the Agile framework being used (e.g., Scrum, Kanban). Therefore, the correct answer to the question is d. All, as both Waterfall and Agile include phases and tasks, but the number of common phases and tasks may vary.
