I'd settle for keeping the respective areas neat. The electronics area is a disaster pretty much full time. I'm forever cleaning up scraps from around the 3d printers. The textiles area is an amoeba that seems to claim another few sq ft every time I come in with almost no one working there while I'm in (I'm certain it gets used btw, not debating that)
The same can be said for the wood shop. The machine shop is still shaking out in terms of organization.
Tom, I love the parking ticket idea, but like the red tag system for broken equipment, it isn't getting used. I suspect because no one knows where to find the tickets or red tags. There should be a bunch in a holder in every room. Or on the volunteer desk. I don't care where but they should be out in plain sight.
Several folks started to take on the clutter of the storage hallway but left the job 30% done, with the remainder scattered about the floor. That's a far larger problem in terms of optics.
To me, the key is the enforcement by the volunteers. A quick report on what it looked like at both ends of the shift is enough to start to identify our troubles. And cameras. Lots of cameras.
