The five original elements of Crew Resource Management (CRM) are:

• Inquiry
• Advocacy
• Conflict Resolution
• Decision Making
• Critique

Most pilots have become proficient in the first four elements, but frequently the Critique element is ignored. A properly conducted Critique allows you to evaluate how the flight went and to learn from successes and failures of the flight's activities.

Basically, when conducting the Critique, you consider what went right and what went wrong, and what you would do differently if given the opportunity to conduct the flight again. It is comparable to the post-flight Debrief process conducted by military pilots.
