e Process Capability PART 1 Hop Scotch Drive-In Restaurant is considering a new marketing idea. At Hop Scotch, diners have the choice of dining inside or staying in their cars to eat. To serve those dining in their cars, carhops take the orders at the car and bring the food to the car when it's ready. Many people want fast service when they pull into the drive-in restaurant, but they also want more than a drive-through restaurant can offer. To try to meet their customers' expec- tations, Hop Scotch Drive-In is proposing to promise to have a server at your car in two minutes or less after your arrival at their drive-in. Before making this promise, the owners of Hop Scotch want to see how long it takes their servers to reach the cars now. They have gathered the information in Table C7.1.1. CASE STUDY 7.1 ASSIGNMENT Calculate the range for each of the subgroups containing five server times. Since the owners of Hop Scotch Drive-In are interested in the combined performance of their servers 1234 DETE POHS 2359 828 TABLE C7.1.1 Server-to-Car Times in Minutes Subgroup Number 10 11 12 13 14 15 16 17 18 19 20 Server 1 2.5 2222 6543 2.5 2,4 2.3 2.3 2.6 2.7 2.4 2.5 NNNN 2.4 2.5 2.4 NNNN NN NN 2,5 2.5 5546 2.4 2.6 2.0 0233 2.2 2.3 2.3 Server 2 2222 2.4 22 2.5 4254 24 26 2.4 2.6 2.3 2.2 2.4 2.4 2.3 NNNN 2.5 24 2.3 2.7 2.3 24 2.5 2.5 NNNN Server 3 mani 23 24 Process Capability 253 and not the performance of any particular server, the sub- groups contain times from each server. Use these calculated values to determine the process capability and the C, and Ca values. How well is the process performing when com- pared with the specifications of 2.0 min +0.0/-1.0? 2222 PART 2 Judging by the time measurements, it now takes longer to reach the cars than the proposed two minutes. Hop Scotch probably won't be able to keep up with their ad- vertisement of two minutes or less without some changes in the process. The process capability index is too low. The C shows that the process is not centered around the center of the specification. In fact, the Cpk value tells us that the average for this distribution is outside the speci- fications. Management has decided to explain the proposed advertisement to their servers. They hope that by doing this, the servers will put more effort into getting to the cars in two minutes or less. Management carefully explains how moving faster to get to the cars will have a positive effect on increasing business because the customers will be happier with faster service. At first skeptical, the servers decide it might be possible to increase business by serving the customers faster. They agree to do their best to get to the cars as quickly as possible. The time measurements seen in Table C7.1.2 were made after the meeting with the servers. 2.7 4645 2.5 24 2.6 24 2.5 HNG NH Nhn 23 23 2.5 24 24 2.3 2.6 2.6 2.3 24 22 21 Server 4 2.5 2.3 53551 ~~~~ 2.5 2.9 2.7 2.5 24 26 2.4 2.7 2.5 22 2.5 23 2.4 26 27 29 2.4 2.6 Server S 2.1 2.8 2.5 2.9 22 2.5 25 24 NNNN. 7431 2.7 2.4 2.3 2.1 2.7 2.6 2.8 2.9 25 2.6 2.3 2.5 Range 0.4 dddd 4636 0.6 0.3 0.6
