What is the difference between an evaluation and an impact analysis?

The terms ‘evaluation’ and ‘impact analysis’ are often used interchangeably, but they are not the same. In this article, you will learn more about the difference. But to start with the essence: the most important thing is to think as early as possible about the impact you want to create and take action to achieve it.

Evaluation = How you can improve your activities

The term ‘evaluation’ is a broad term. You can evaluate virtually anything, and you can interpret it in (at least) two ways.

  1. Evaluating your work to improve the way you carry out your activities, thereby improving outcomes for your stakeholders; and,
  2. Evaluating your work to improve the outcomes of your work for your stakeholders.

You can conduct an evaluation without explicitly measuring whether anything has changed for your stakeholders.

Impact analysis = How you can measure whether change has occurred

The impact of your activities is measured by analyzing whether they have led to change(s). Often, to truly assess the impact, you would need to measure a situation both before and after an intervention or activity. In some situations, this is not possible. For example, when you try to understand your impact after a project has ended or when you cannot collect data at the beginning.

Sometimes a change that occurs is unexpected and only becomes apparent afterward. In theory, you can conduct an impact analysis without analyzing how you could improve your activities.
