The exercises described in this report represented collaborations between people familiar with local circumstances and people from outside the participating jurisdictions who had expertise in exercise design and facilitation. Because we did not test an alternative approach that exclusively involved local personnel, it is difficult to generalize from this experience about the value of engaging people from outside the participating agencies. Nonetheless, it was our impression that at certain points in the development, facilitation, and feedback steps, there was value in involving people who were not personally invested in local relationships or situations and who could offer seemingly independent advice or perspectives.
