Simon,
I understand your sceptisism, but the Balanced Scorecard approach is a well documented management approach developed by a group of people from Fortune 500 companies under the guidance of Dr. Robert S. Kaplan, the Arthur Lowes Dickinson Professor of Accounting at the Harvard Business School.
The idea is to create metrics that will give you a holistic view of your company and that are linked to your strategy. It will make sure you measure financials (as you still do need the money :-), but also keep an eye on how your customers perceive you, the internal processes that are critical to your success and the knowledge and resources needed to sustain your business model.
It is human (or organisational) psychology that what is being measured by the company gains importance and focus. That's the whole idea of performance measurement. What is important about the Balanced Scorecard approach is the way you decide what to measure and the above mentioned holistic view. I hope you agree on that. :D
The Balanced Scorecard has been kind of "reserved" for the big corporations due to the silly pricing of the software needed to create a good scorecard. My exitement was simply due to the fact that I found a solution that works and doesn't set me back $100,000 as my budget would no way allow that. :P
So grab your card, Simon!
Sebastian
