We have gotten pretty good at the whole time management thing over the years. I am an Automotive Engineer, and I am used to coordinating big projects with lots of players and lots of facets. FRC is very similar, just way faster. I will say that we have learned a lot about process from the good teams. Talking to 111, 217, 469, 1114, 67, 148 and others has really inspired us to get our act together. These teams do great things and you can really learn a lot from them.
Most of my team are not quite as fanatical as I am. Most of our team works in phases, where some do a ton of work in the build season, and some do a bit more in the testing and training phase. Many people rotate days off. I am pretty much there all the time, but I have found ways to deal with this. Efficiency is the key for me. If I have a plan, a design, the tools, and people with the skills, it is amazing what can get done in a short period of time. I run a plan/execute cycle on about a 1 day loop all the way through. We also have the blessing of a fantastic parent support group, so basic needs like food and Mountain Dew just seem to appear as if by magic exactly when we need them.
