Performance cannot ever be maximised because there will always be constraints. When the constraint is budget, the real question is how to get the best performance within that budget. The answer lies in who defines ‘performance’.
In our search for how to choose meaningful targets for our KPIs and performance measures, we often look for a procedure or a formula to set the right KPI target value. But what we ought to do before that, is check if the conditions are right for any KPI target to work.
Most performance measures or KPIs will have targets. After all, we have them to focus us on improving performance. But that focus can fracture if we don't take care in how we express our measures and our targets, so they speak the same language.
