Yeah, I apply all kinds of thinking to this, since it IS a business. I'm not huge on six sigma, but I do agree that waste is what kills you with music. Cost of rehearsal space, driving to and from, maintaining your equipment and the like all add up quickly. So, putting some industrial thought to the music biz doesn'r hurt.
One of the things I teach all the bands I mentor is the cost of an actual show. I add it up in hours. Choosing a set list. Rehearsing for the show. Driving to and from rehearsal. Maintenance on instruments and amps. Driving to and from the show. Load in time. Sound check time. Actual performance, load out, and the obligatory "band can't leave until the end of the night" time. Really puts it in perspective for these kids.
For a 45 minute set an original band can put in easily three hours of rehearsal, another 4 hours of driving to and from, a couple of hours for band report and load in/sound check, then an hour waiting, an hour playing and breaking down, 30 minutes to load out then another hour to drive home. So lets put it at 12 hours invested.
After the set the band at the end of the night is handed their piece of the door, which for many is usually about $80 to $100 max. Divide that by the normal band size of 4, and you get $25 per person max. Then divide that by 12. You just earned gross $2/hr. Take out, in theory, taxes and your other expenses, and maybe you got $1 per hour.
So, using that LEAN approach and minimizing waste is important. Also makes for better decisions. Converting a space into a rehearsal room = $$$$ in your pocket. Being on time for rehearsal and not f'ng around - $$$$ in your pocket. Keeping things as local as possible = $$$$ in your pocket. Cleaning your bass and amp after every gig and not putting the volume on 11 = $$$$$ in your pocket.
Most of the kids don't even understand those concepts. They bang the living crap out of their instruments, whack 'em up, and don't think about how down the road it will cost them four times as much to replace that or that at some point it will cost them way too much in repairs.
I teach all the bands I have managed how to change oil and do simple maintenance like brakes on their tour vans and remind them to check all the fluids every morning before going anywhere. Also, I tell them to at least rinse the van off as often as possible when on the road because, like UPS found out, you can save tons of money on gas that way.
Not quite sure how you would create a Shewhart chart for a set list though.....
