As Kathrine said, there hasn’t be any “after” or “between” for us as we are trying to develop new sites, but there is “before”.  I feel we learned a lot from the “before”, for example the pacing of our engagement activities. We had a good start with lots of activities that would build our relationship with sites and communities. but the challenge was that as our trial was delayed, and our program activities finished and funding became tight, we didn’t have enough to sustain the relationship building. Looking back, I think we should have better anticipated changes in reality and circumstance, and develop a longer term engagement plan that could have sustained some engagement activities in spite of hiccups and delays.
