- Evaluation should bring all the evidence together
- It allows the comparison between initial aims and final outcomes.
- Evaluation should begin early, even during the planning phase.
Example: A recycling project.
- Measure the amount of waste being placed in normal waste disposal.
- Make the necessary changes to current practice.
- Give the project some time to evolve and catch on.
- Measure the impact of the project by measuring the amount of waste now being diverted from normal waste disposal, now being recycled.
This can be measured by weight and can be converted into monetary savings.
Showing how money can be saved while benefiting the environment will go a long way towards encouraging administration and managers to make sustainable and beneficial change.
