I was able to calculate Server Time at Point of Sale (Cycle Time from order beginning to paid), and the iPhone App then calculated an Individuals Moving Range (IMR) Control Chart as well as a Run Chart. Pretty cool. And, to have the ability to do on-the-spot time studies like this is invaluable for me &#8211; while at the Gemba, I can do a time study and have the data calculated and visualized for me immediately. Very helpful.<\/p>\n<p>Here&#8217;s the Point of Sale distribution at the McDonald&#8217;s. Each unit is a paying customer and I calculated their time from the beginning of giving their order to the time when they received their receipt.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-10210 size-full\" title=\"mcdonalds-franchise-information-1\" src=\"https:\/\/staging.opexlearning.com\/resources\/wp-content\/uploads\/2012\/04\/mcdonalds-franchise-information-1.jpg\" alt=\"mcdonald's cycle time at the service counter\" width=\"480\" height=\"300\" srcset=\"https:\/\/staging.opexlearning.com\/resources\/wp-content\/uploads\/2012\/04\/mcdonalds-franchise-information-1.jpg 480w, https:\/\/staging.opexlearning.com\/resources\/wp-content\/uploads\/2012\/04\/mcdonalds-franchise-information-1-300x187.jpg 300w\" sizes=\"(max-width: 480px) 100vw, 480px\" \/><\/p>\n<p>Here is the same data, but the iPhone App calculated the IMR Control Chart, showing Upper Control Limit (UCL) and Lower Control Limit (LCL).
