Rolf Reitzig: Unthethered Activities and Costs of Quality

Hello, I am submitting two entries for consideration: Untethered Activities and Costs of Quality.  I wrote these while on vacation so they are not perfect.  If they are of enough interest to include in the book we can get them there.  I've presented each in numerous international forums and they are always thought provoking and generate lots of discussion.  Comments are appreciated.
