a travel agency is concerned with the accuracy and appearance of its itineraries prepared for its clients. Defects can include errors in times, airlines, flight numbers, pries, car rental information, lodging, charge card numbers, and reservation numbers , as well as typographical errors. As the possible number of errors is nearly infinite, the agency measures the number of errors that do occur. The current process results in an average of 2 errors per itinerary. The appropriate control chart for this problem is the C-Chart, which is used for controlling the number of defects when more than one defect can be present in a service or product.
