Free PMI Project Management Professional (PMP) Practice Question

The correct answer is Agile methodology. Agile is well-suited for projects with frequent changes, evolving requirements, and a need for incremental delivery of products. Agile allows for adaptive planning, evolutionary development, early delivery, and continual improvement, and encourages rapid and flexible response to changes, which makes it ideal for the described scenario. Other methodologies like Waterfall or PRINCE2 are less adaptive to frequent changes, as they follow a linear and sequential design process which is less flexible once a particular phase is completed. Six Sigma focuses on quality improvement and may not address the need for flexibility and iterative delivery in isolation.
