I've used this exercise a few times in training people from development and security agencies in countries supporting SSR (e.g. UK). It is a good one, as it's fairly easy for participants to identify concrete strategies for gender-responsive police reform. One thing to actively manage as the trainer is the liklihood that some of your participants may have actual on-the-ground experience of the Kosovo police reform process, or have read about it. You do not want the trainees' discussions to be too constrained by what 'actually happened', as this is an exercise in which they are encouraged to be creative. Likewise, you don't want a few individuals with direct experience to dominate. One suggestion is to say at the outset something like, "For the purposes of this exercise, pretend that you don't know anything about the actual outcomes of the police reform process in Kosovo. Later on, I'll ask any of you who were actually involved to share your insights". This then deepens the exercise by allowing the real-life challenges and achievements to be part of the final plenary discussion.
