411A- Intersting to note %MAC's comment, that those individuals who think it's a waste of time are generally the ones who need it most.
Reviewing accidents is well and good, and a good source of discussion, however, sitting here with 20/20 hindsight after any event means that this exercise is limited in it's use. Errors are easily spotted when the final consequencies are already known!
Surely life is too short for each of us individually to make the same errors that others have made previously. The whole point of CRM is to ensure that communication within the team is effective to help prevent the error chain that leads to a more serious incident occuring.
