I did do a cursory search through the forums about the scheduling of O3s. BLUF: I have 4 directs in a K-12 school environment (I'm the CIO, they are Techs and Sr. Techs) and I'm wondering what scheduling-wise has been effective for those that have done O3s for a while and have had success with them? For example, if you were in my situation would you do two a day back-to-back? At only 1/2 hour a piece it seems pretty attractive to me to simply schedule a 2 hour block and knock them all out in one day. I find that mornings work better due to queuing theory. Thanks in advance!
