PMI Agile Certified Practitioner (ACP) Practice Exam

Which describes the approach of the Waterfall method?

1. Highly adaptable to change throughout the process

2. A systematic progression through defined stages

3. Frequent user testing and feedback during development

4. Agile mindset fostering collaboration

The correct answer is: A systematic progression through defined stages

The Waterfall method is characterized by a systematic progression through defined stages, which typically include requirements gathering, design, implementation, verification, and maintenance. Each phase must be completed before progressing to the next, and there is generally no going back to a previous phase once it’s finished. This structured approach allows for clear milestones and documentation, making it easier to manage large projects with specific requirements. Because each stage is distinct and sequential, it emphasizes thoroughness and completeness within each phase before moving on, which is a hallmark of the Waterfall methodology. In contrast to this method, other approaches mentioned—such as being adaptable to change, emphasizing frequent user testing and feedback, or fostering collaboration—are more aligned with Agile principles. Agile methodologies prioritize flexibility, iterative development, and active stakeholder engagement, which starkly contrasts the rigid structure of Waterfall.
