You've decided to calculate the DPMO and sigma level of your local Starbucks' delivery cycle time to see how well they've been serving you. You've determined your measurement system and data collection plan are sufficiently robust. You realize, much to your chagrin, you've consistently stopped by for a coffee four times a day, every day, for the last thirty days. Your CTQ is it takes no longer than 2.5 minutes to deliver your coffee from the time you order it. You note they did not meet your CTQ thirty-two times during that period. What is the process DPMO = (DPO * 1,000,000) and approximate short term sigma level? 78,125 and 2.6 3.4 and 6 6,200 and 4 266,667 and 2.1
