A couple of months ago, we instituted a mandatory meeting 15 minutes before the regular "start time" that involves the crew leaders, the ops manager, and the sales team. We go over the day's jobs, and make sure the crew leaders have the gear they need, and the proper run down of how the job should go. We also take that time to go over jobs from the day before, if the crew wants to let the sales guys know about something (like not mentioning the huge power lines right next to the tree to be pruned, or poison ivy).
It started out slowly, with some habitual lateness with several guys, but now, two months later, we all know where we are supposed to be, and the jobs are going much smoother.
We have fuel at the shop, diesel, gas, and off-road diesel. We have found that beyond the controlled expense of the fuel, our guys have no excuse to stop at a store on the way to the job.
Communication is the key to getting this job done. If there is a disconnect between the sales/management and the crews, it will start to wear away at morale...ultimately dropping productivity and could result in higher turnover.
