Making good decisions is an iterative process. It is a skill that although uses analytical tools it can require some time to learn. It would be very useful to reflect on the decision making process and methods to understand what went wrong to avoid it and what went right to keep it. By continuously following this process the human decision capabilities can improve.
This is important as those analytical skills require practise to be performed in a competitive level. Moreover, with reflection the decision maker can become aware of personal preferences, heuristics and biases.
In my work we keep a log of snags using a software as a part of lessons learned. It would be very useful to document the decision making process to allow the department not just to gain knowledge on how a certain fault is rectified but to record how robust decisions and analyses are carried out to meet the system operations objectives in terms of decision making.
