Assignment:
A & A Enterprises ships integrated circuits to companies that assemble computers. Because computer manufacturing operations run on little inventory, parts must be available when promised. Thus, a critical element of A & A’s customer satisfaction is on-time delivery performance. To ensure that the delivery process is performing as intended, a quality improvement team decided to monitor the firm’s distribution and delivery process. From the A & A corporate database, 100 monthly shipping records were randomly selected for the previous 21 months, and the number of on-time shipments was counted. This information is contained in the file A & A On Time Shipments. Develop the appropriate 3-sigma control chart(s) for monitoring this process. Does it appear that the delivery process is in control? If not, can you suggest some possible assignable causes?
Your answer must be typed, double-spaced, Times New Roman font (size 12), one-inch margins on all sides, APA format and also include references.
