Dr. Thomas is a physician employed by a large hospital by a large primary care hospital in Cedar Rapids, IA. The practice in which he works is open 260 days a year. Physicians have 30-minute appointment slots starting at 8 am all the way up to 6 pm. The practice is looking for improvement opportunities and wants to get a sense of the Overall People Effectiveness (OPE). The data collected so far suggests that:

• Dr. Thomas spends 30 workdays with his parents in Greenbay a year on vacation.
• He also looses 2 hours of potential work time each day due to electronic medical record keeping (He blocks these 2 hours in his schedule, so no appointments are available during this time).
• Dr. Thomas has a really busy schedule, so 75% of his appointments are booked.
• About half of the patients Dr. Thomas see are coming for their annual check up. Such exam appointments are made a long time in advance. About one out of every six patients does not show up for his or her appointment.
• Though the appointment slots are 30 minutes per slot Dr. peters only spends on average of 23 minutes with the patient (or doing work related to the patient after the patient has left the office). Of those 23 minutes about five minutes could easily be done by one of Dr. Thomas' assistants.
