Rob May won the ‘best management idea’ contest. His basic concept:
One thing I do that isnâ€™t very common is that I write down the decisions I make and the projected outcomes. Each week, I take a few minutes at the end of the week and I make a list of decisions I made. I try to focus on decisions that have important consequences, have ambiguous input parameters, or are otherwise difficult to evaluate. I donâ€™t waste time on simple things, although at some point I probably should take a few weeks and just focus on those.
There’s a lot more there, you should definitely read it and think about how it could apply to your own working life.
