A "balanced" set of measures is one which includes metrics which represent several perspectives.  An unbalanced set of measures might be one where all measures are revenue-related, overlooking internal development or customer service imperatives.

Another guideline to use when identifying what metrics to include in your Balanced Scorecards is practicality.  Selecting too many measures, or measures for which performance cannot be reliably determined each period, can lead to incomplete results.  You need to build a set of measures you can work with for the long run.

PM-Express handles your measures as you define them to match the real world, including financial amounts, raw numbers, percentages, and simple Yes/No indicators.  Each metric holds Planned, Current, and historical performance values.
