Part 1 of 2 parts For the last 30 days, a hotel kitchen manager tracked the number of defects in breakfast deliveries and needs to estimate process capability.  Twenty (20) breakfast orders were inspected each day for 5 specific defects:  on-time delivery, coffee drink (including tea), main selection, side dish, and bread.  For the breakfast orders that were inspected, 37 orders were found to have a total of 73 defects.

A manufacturing engineer conducted an MSA study to qualify a gage used to measure a critical characteristic of an injection-molded part. The specification limits for this characteristic are 685 ± 0.5 mm.  Two operators were selected randomly from those who would normally use the gage. Ten parts were selected at random from parts produced on one shift. The procedure was to load each of the ten parts into the gage twice and to record the measurement as the deviation from the target specification value. Which metrics should the engineer use to evaluate the measurement system?
