When I was working as a pilot, like both of you, I thought that TEM was just another generation of CRM. However, I’m currently undertaking postgraduate study in human factors and I can understand the difference. Put simply, TEM was a framework for identifying deficiencies and strengths within the operational area of an organization, with CRM as a set of countermeasures. Now, TEM is being applied to the flight deck and used as a tool for increasing situational awareness, or what we think of as that illusive and indefinable quantity of ‘airmanship’. It has proven to be a very useful tool, and there is a lot of empirical evidence to back up its claims. So give it a chance and you might be surprised
