Impact evaluation or assessment provides a way for governments and organisations to measure and assess the success of their programs and policies as compared to their stated goals and objectives. The initial step in this process is to conduct surveys of the particular sectors (industries, firms, regions etc) to be assessed. Such surveys establish the initial conditions against which program outcomes can subsequently be measured.
Knowledge arising from impact evaluations will allow governments and organisations to monitor the success (or otherwise) of programs, interventions and projects against economic, social and environmental objectives. Further, such assessments will ensure that decision-making is well-informed, transparent, and efficient.
