How to set objectives
In planning evaluation, it is important to be clear on the objectives of the service/intervention. There are two basic questions to ask:
Once you are able to answer these questions expand your thinking to consider what funders, society, the economy or the Government may be able to gain through your service.
Ideally you will plan your evaluation at the same time as you are planning your programme. The first step is to define success. There is no single answer to this, it will depend on the intervention, the time and resources you have available and what you can practically measure.
There are three key factors that make up a robust evaluation.
It is important to include both quantitative information (facts and figures) as well as qualitative information (case studies and customer views).
There are varying levels in terms of how robustly you can measure impact. The most appropriate for your intervention will depend on the scale of the intervention, feasibility and resources available to carry out the work.
- Time series analysis – take a baseline measure at the beginning of the intervention and compare with the end results to identify progress.
- Time series analysis with a control group to identify the added value of your intervention as opposed to other influencing factors – compare your client group with a client group with the same characteristics that did not experience the intervention. Ask the same questions at each stage.
- Randomised control trial – As for 2 but the trial is done with sufficient numbers to ensure that the results are statistically significant. The control group is randomly selected. This is only suitable for fairly major projects.
