I've been working on a managerial decision making process for one of our VPs. I know, I know, sounds like a set-up for a Dilbert strip. But really, it's very comprehensive - it factors in financial formulas, risk assessment, and 12 other criteria. It's going to be used for those big, honking, complex decisions that can make or break the company. It's proprietary, so too bad I can't share it with you.
However, I can share with you a decision making guideline that should work for about 99% of the rest of the decisions that we face in our day-to-day lives. I got it from Tom Peter's blog. He found this card in a Boston card shop:
"Ever notice that 'what the hell' is always the right decision?" - unknown Hollywood script writer, (courtesy of The Borealis Press).
Tom's advice: At some point (today), despite "overload", just say "what the hell", and go for it!
(Likewise, worry if it's been more than a week or so since you said to yourself, "what the hell.")
