What tool is primarily used for conducting after-action reviews?

The tool primarily used for conducting after-action reviews is the Conduct of Operations (COO). This tool allows leaders and teams to analyze and evaluate the actions taken during a particular operation or training exercise. By using COO, individuals can systematically assess what went well, what did not, and how processes can be improved in the future. It emphasizes learning from experiences to enhance overall effectiveness in operations.

The COO is integral because it provides a structured approach to feedback, fostering an environment where lessons learned can be documented and shared among the team. Its focus on collaborative reflection enables a comprehensive understanding of performance, which is crucial for developing strategies to improve future operations.

Other options may have specific functions, such as performance evaluation or leadership assessment, but they do not serve the central purpose of facilitating collective reflections on actions taken in a specific scenario like the COO does.
