The ultimate reality is that most organizations don’t have a scorecard.
They lack activity-based numbers to review on a regular basis.
They might rely on P&L (profit and loss statement) to tell than the score, but by then it’s too late to make corrections.

A profit and loss statement is a trailing or lagging indicator. Its data comes after the fact, and you can’t change the past.
With a scorecard, however, you can change the future. The key, of course, is to create a scorecard that fits your unique business.
Start with activity-based numbers you can check every week, such as leads, calls and deliveries on time. Keep the list short, review it with your team, and change it as the business changes. For the profit side, have a read of what is profit margin. There is also a general page on key performance indicators on Wikipedia.
