When I worked for a window manufacturer someone from the office was stretching their legs and wandered through the shop. In light conversation they mentioned that when glass was ordered for a job 10% extra was order in case of breakage. That got around the shop.The biggest is the size of the civil service. Do like a big business - hey managers, 10% reduction in budgets, figure it out. Or we’ll get someone capable to do it for you ( get the hint?).
Suddenly the receiver got clumsy unloading trucks. The cutter wasn't as diligent with optimizing. The labourers were careless shifting the glass to the assembly area. The assemblers used a bit more brute force.
We ran out of glass.
My accountant figures they lose an hour a day to net surfing and personal texting, shopping etc. That's like losing a day a week from each employee. IMO grab a bunch of out of date computers and put them in the lunch room, disconnected from the company system. Do you shopping and personal browsing on your lunch and coffee breaks.
