Perfect is the enemy of good, and no plan survives contact with the customer. Â Analysis paralysis delays so many great ideas, and fear of failure kills so many creative initiatives.
Unless lives are on the line, live by the tracer bullet theory. For the uninitiated, the idea is that in the field you can set up your mortar, calculate the distance of the enemy, set the angle, adjust for wind, and by the time you fire the enemy has moved across the battlefield. Or you can fire quickly in the general direction and make rapid adjustments/corrections as you quickly discover what is and isn’t working. While you’ll most likely miss on the first shot, you’ll be directionally correct and with a few small adjustments you’ll be successful.
“Nobody ever got fired for buying IBM” may be true, but is being the guy who didn’t get fired really what you want to be known for?  Me neither.
