What is a key principle of Agile Project Management?

A key principle of Agile Project Management is indeed shifting the focus towards customer interaction and flexibility. Agile methodologies emphasize collaboration with stakeholders and adaptability to changing requirements. This approach advocates for frequent communication and feedback, allowing teams to respond quickly to changes and better meet customer needs.

In Agile, the goal is to deliver functional increments of product value rapidly and efficiently, which reflects a strong emphasis on customer satisfaction. By prioritizing flexible planning and continuous improvement, Agile teams can adjust their course based on real-time insights and shifting user expectations, ultimately leading to a more successful project outcome.

The other options, while they may represent traditional project management practices, do not capture the essence of Agile. Following rigid processes can inhibit responsiveness, limiting changes to the project schedule contradicts the core Agile principle of adaptability, and extensive documentation is often less emphasized in Agile in favor of direct communication and working solutions.
