Disorganised Customers

My on-site project has reach a point where my customer wants to do some tests on the robot because the plant will be shutdown again next week. This will involve some fairly non-trivial changes to the hardware which was never really intended to be field upgradable. When I explained the procedure for changing the hardware, I could tell that no one else had given it much thought. They were even slightly dismissive of the possible problems I described. Under those circumstances, the obvious course is for me go to the plant, but when I left at 6pm, I still did not know the schedule for next week. I get the feeling it is going to be hectic.
