Identifying a change in compliance behaviour or community confidence does not necessarily mean that your compliance strategies caused that change.

Using a comparison technique enables you to separate the effects of your strategies from other factors that could be causing the change. This will help you to identify whether the observed change is a result of something you have done, or a reflection of changes in the environment that are outside your control.

Several different types of comparisons can be used - some are suitable for high- level measurements (for example, benchmarks), while others are more suitable for drilling down to a sub-population level (for example, target and control group studies).
