Just before Christmas, I had a looong discussion with a friend who just entered Decision Analysis studies – a field I wasn’t even aware of until then.
Given that life for a project manager is full of decisions, studying how to do that well (both the preparation and the eventual commitment of resources) sounded like a treasure trove.
The next day, I told my boss about this discovery. He already knew what this was all about and started raving about applied maths from the lectures during his MBA. Then he quoted from his lectures:

Decision analysis serves to create transparency over actual preferences. That’s why it is rarely used in practice.
