Key features

The guide sets out five key challenges that the authors have noted when conducting advocacy impact evaluations:

  1. It’s not always straightforward to set out the contribution problem in the first place
  2. Developing a (good) theory of change takes time and engagement
  3. Existing evidence can be weak and/or unavailable
  4. Contribution stories can take many forms
  5. Gathering additional evidence can be a challenge

It then offers four lessons learned and provides information about the practical management of the approach. The lessons learned are:

  1. Start at the end
  2. Accommodate uncertainty
  3. Understand what is ‘enough’, and make the most of what you’ve got
  4. Bring people along the journey
