The Way Forward in my mind seems to be about dramatically increasing critical mass. It seems like a team of 10 could efficiently generate AND retain critical mass consistently.
Here's another thought:
What if we as individuals/teams/RDs/NDs were accountable for spending 70 percent of our time on generating NEW critical mass, and 30 percent on retaining/developing critical mass, and left the remaining energy/time it would take to retain and develop to students/volunteers/pigeons/whoever was willing to help. My guess is in that just a couple of years we may have 500 staff to send!
