A key problem that a number of people encounter is to determine whether a measurement should be used as a Key Performance Indicator (KPI). For a KPI to be effective it must be a good measure of the current or future status of the thing to be measured.
As the adage goes, if you can't measure it, you can't manage it. The problem is that if you measure the wrong thing you may end up with less than desirable results.
This decision tree is a small aid to assist you in clarifying your thinking about whether something is really a KPI or yet another measurement. Remember not everything can be a KPI and you really should choose the best measurement to track the performance of the thing that you are trying to monitor or improve.
