TDODAR is a decision making tool - BA prefer TDODAR, I've used something similar in a previous (non-flying) career and there are many out there with different names, but the process is not-dissimilar
Basically
T - Time - how much time do we have
D - Diagnose - What exactly is the issue?
O - Options - What are our different options for dealing with it
D - Decide - Select the 'best' option (this is an important step - selections should be based on some sort of criteria - not just a best guess or coin toss!)
A - Action - Action what needs to be done
R- Review - Very important - go back and review whats been done. Sometimes a good review is a 'negative' one. Actively look for things that could contradict your origonal analysis.
