Can you actually fall in love with an application? We hopefully not, unless your a robot. You can be smitten with one, and I am definitely with Business Scorecard Manager.

The basic business under pinning is the Balanced Scorecard Approach, which all the rage in business schools.
You can read any number of books on balanced scorecard here:
