The best lesson I ever got about goals I got from learning to play (6-max, limit, texas hold'em) poker. Poker has stupidly high variance to profit ratio, and an endless amount of metrics you could measure to track progress. Obviously, the goal of playing is to make money, and almost equally obviously, focusing on how much money you made is actively harmful if done for sample sizes lower than 100k hands or so. The solution to improvement through quantitative analysis in that environment is to find key drivers that you believe impact your overall goal, analyse trends you see in those drivers, and based on those find a few areas that you want to qualitatively drill into to figure out changes you can make. I.e. - "I open 20% of the time from early position and 25% from late position - if I compare to other successful players that is too low a difference, so lets see if I can find some situations where I may be making bad decisions and plug those holes". That is what we want to do with goal setting in business as well. Yes we have some high level KPIs that we want to improve, but actively working "to improve your revenue" is harmful and will no doubt lead to selling cars that explode etc. To be successful you set your overall KPI(s), then you forget about it and focus on smaller things that will over time incrementally add to your overall goal. If you have managers and employees who cant make that separation or want to take short cuts to directly affect the overall goal without focusing on the smaller bits, or comparing to some kind of "best known" practise, then you end up with exploding cars, tools that has all features and no usability etc. |
Ending up with an exploding car is also an end result of premature optimization. It means you're focusing on revenue to an extent that is counter-productive.
That means that revenue isn't the overall goal, either. The overall goal is "an ever-flourishing company".
KPI is only one way to try and marshall the resources of a company to move in the right direction, but it seems easy to use wrongly, leading to balkanization of departments, etc. The other way is to use a system like Theory Of Constraints, which encourages a systematic view of the company's overall goals, that is transparent down through the implementation levels, and do regular constraint analysis to identify the (ever-changing) root constraints that block progress towards the overall goals.
