In the hit movie "Jerry Maguire," Tom Cruise's character declares, "Show me the money!" Well, if Jerry wanted to be a successful entrepreneur, he should have been shouting, "Show me the metrics!" One of my last programming jobs - before I created my own company - was for a company who had the catch phrase, "You can't manage what you can't measure." Without the ability to quantify your business through metrics, sometimes called KPIs (Key Performance Indicators), the business is totally reliant on the instinct of the owner.
