Crew Resource Management (CRM) is a set of training principles originally developed in aviation to improve safety by enhancing teamwork, communication, and decision-making among crew members. CRM emphasizes the importance of clear information sharing, mutual respect, and collaborative problem-solving to minimize human errors and manage risks. While first used in aviation, CRM concepts are now applied in other high-stakes fields, including healthcare and cybersecurity, to help teams work more effectively under pressure and prevent mistakes.
