I haven't done math/stats/etc. in ages. When I look at the numbers they look right, but this just seems wrong. It seems impossible, and unrealistic. Someone double check my math.

Code:

Code

Work Days /yr		256 Hours /day		7.5 Hours /yr		1920 Max Mistakes /yr	10

So there is your data for how many days worked per year, how many hours worked (8 hours, with 30 minutes of break time) and the guidelines for the number of mistakes a worker is allowed to make in a year. Let's pretend this is a factory line, doing part assembly.

Code:

Code

Parts Per Hour	Error Allowance 3		0.1736% 3.5		0.1488% 4		0.1302% 4.5		0.1157% 5		0.1042% 5.5		0.0947% 6		0.0868% 6.5		0.0801% 7		0.0744% 7.5		0.0694% 8		0.0651% 8.5		0.0613% 9		0.0579% 9.5		0.0548% 10		0.0521% 10.5		0.0496% 11		0.0473% 11.5		0.0453% 12		0.0434% 12.5		0.0417% 13		0.0401% 13.5		0.0386% 14		0.0372%

The number seem right. 1920 hours per year. If you move 5 parts in an hour you move 9600 per year. If you're allowed to make 10 mistakes in a year (pass/fail)... 10 out of 9600...

Judging by these numbers you're better off being a total slacker than actually being productive. Since 10 mistakes is a failing grade you're better off scooting by and passing both productivity and quality than you are being exceptional in productivity but failing quality with 11 mistakes.

Anyone with an MBA have any insight into this logic? I knew when they told me these numbers something was hosed up with it, and crunching the numbers either means I'm really bad at math or somebody is really unrealistic.
