General HR Question:

I have been working at a senior level since last many years. These roles have always needed me to make real time decisions. Sometimes the facts, figures and other information in real time cases are not complete & still we have to make a decision. In such cases, there exists a probability of making inaccurate decisions.
Knowing this, I usually run down my old decisions to see the outcome. It makes sure that I don't repeat a mistake ever again in future. While carrying out one such exercise, I realised that the product promotion strategy that I recommended would have been different, if I had had the complete data and figures but there was no way to get them in real time.
