June 2, 201412 yr Hi Team, Need your advice.... how we can measure Accuracy of the SLA... sounds very simple... There is an Client SLA where team has to maintain 99% accuracy for each cases... Team receives different cases from client where each cases is different from the other, CTQ wise certain CTQs are similar to each cases and some are different. So we have different opportunities for each cases.... In this situation we cannot have constant value for each cases as denominator to measure accuracy.. Below mentioned are the few samples taken from the monthly volume data... where we identified the actual opportunities from each cases.... Day Volume/Cases Total OpportunitiesDay 1 123 98Day 2 143 22Day 3 109 62Day 4 112 29Day 5 141 40Day 6 121 62Day 7 132 63Day 8 145 81Day 9 138 88Day 10 104 22Day 11 144 81Day 12 115 38Day 13 135 21Day 14 138 65Day 15 123 95 On a monthly basis the volume or cases used to be in an average of 1456 cases.... how we can measure its accuracy.... (client target 99%) Challenging part is to identify opportunities count for each cases as it is one of the time consuming activities....how we can resolve such constraints.... Hope you understood the concern....

September 2, 20169 yr Dear Rajiv Hope this helps if iam not late. When we visit "Subway" for a roll. We have these chefs work on each roll different depending on the request. Well the CTQs are similar in all of their delivery, yet the taste varies depending on the activities while making the roll. If he adds too many vegetables, or sausages or the meat or underheat the bread - the accuracy with the taste falters. I find your challenge similar to a typical manager's worry on ensuring the right taste of each roll as per their brand( in your case the SLAs ) What I can think of is if we break the activities of these cases as they have similar CTQs into segments( sequential or parallel )/ work blocks and check for the accuracy ( based on the criteria set for each segment) on a random basis and then extrapolate the entire work - we might have an answer. I can also recommend the structure followed by the famous " Dabbawalas" of Mumbai. They break it down into stages, track it and ensure the delivery to the right candidate. Better watch out for Rolled throughput yield. Share your thoughts and good luck. regards Nagraj Bhat

Hi Rajiv, Opportunities need to be counted each time if you wish to use the DPMO method. This will lead to Total Defects out of Total Opportunities over a period of time being utilised for accuracy assessment. If opportunity count is time-consuming and you want to use a method of counting defectives (instead of defects), you have an option. Using this approach, you will lose the level of detail that is needed for analysis and improvement but can give you a reasonable idea of performance.
