Chapter 3, Problem 49P
Metropolitan General Hospital is a city-owned and–operated public hospital. Its emergency room is the largest and most prominent in the city. Approximately 70% of emergency cases in the city come or are sent to Metro General’s emergency room. As a result, the emergency room is often crowded and the staff is overworked, causing concern among hospital administrators and city officials about the quality of service and healthcare the emergency room is able to provide. One of the key quality attributes administrators focus on is patient waiting time-that is, the time between when a patient checks in and registers and when the patient first sees an appropriate medical staff member. Hospital administration wants to monitor patient waiting time using statistical process control charts. At different times of the day over a period of several days, patient waiting times were recorded at random with the following results:
- a. Develop an x-chart to be used in conjunction with an R-chart to monitor patient waiting time and indicate if the process appears to be in control.
- b. The city has established a requirement that emergency room patients have a waiting time of 25 minutes ±5 minutes. Based on the results in part (a), is the emergency room capable of meeting this requirement with its current process?

As one of the largest and most successful airlines in the world, Emirates has built a reputation for providing high-quality service to its customers. However, the company has recently faced several challenges in terms of service operations management.

These challenges have led to flight delays and cancellations, which have had a negative impact on the airline's reputation and customer satisfaction.
Another challenge that Emirates has faced is the issue of overbooking. As the airline's popularity has grown, the demand for seats on its flights has also increased. However, the company has not always been able to match the supply of seats with the…

- In a car manufacturing company, an automated painting process has been introduced, and the quality assurance team suspects there might be issues that require investigation. The team decides to conduct a root cause analysis to identify potential problems. Through the root cause analysis and further investigation, it appears that the drying time of the paint in minutes is affecting the overall quality of the finish. The aspect they need to examine is the variation in drying time across different colours of paint. Considering the ongoing concerns in the painting process, the team chooses to collect a sample of six drying time measurements every 20 minutes from various colours of paint. The recorded drying time values for a day's production are presented in Table 1. A total of 10 sets of measurements, each consisting of six drying time values in minutes, have been collected. Each time a set of measurements is taken, the individual drying time values are recorded.

Dr. Price recognizes the importance of maintaining a good reputation since much of her work comes from previous clients who have been satisfied.
