Effect measurement and evaluation.

Abstract
 The central issues of this final chapter are effect measurement and evaluation of events. It discusses in more detail the Plan–Do–Check–Act (PDCA) cycle, because measuring effects and evaluation are only useful when the PDCA cycle is taken as a starting point. The chapter also describes effects and types of effects in relation to events. In this context, the key question is ‘Who wants to know what, and why?’ The formulation of proper objectives is crucial to measuring effects, as this chapter demonstrates. The chapter ends with a description of how effect measurement and evaluation can be carried out.
