This is the first problem from the productivity module practice problems. In this problem we look at the overall people effectiveness of one physician at a large practice. Remember that an overall equipment effectiveness framework, or people effectiveness framework, in this case, is used to understand what portion of a resource's time is used for work that adds value. And what portion is wasted. The problem statement includes a lot of information. But, the key points are as follows. The clinic is open 260 days per year, from eight AM to six PM. Furthermore, physicians have 30 minute appointment slots to see patients. The physician that we are interested in is Dr. Peters. Dr. Peters has 30 vacation days each year out of 260 total working days. He spends two hours each day for medical records. Notice that the problem states that he loses two hours of work time each day, so that's a pretty good indication that updating records is considered time wasted, not productive time. We are also told that 75% of Dr. Peter's appointment slots are booked. Out of all of the patients he sees, one out of every six patients is a no show. This means that one out of every six booked appointment slots is wasted. Finally, we are told that Doctor Peters spends 23 minutes with each patient, not the full 30 minutes. However, five minutes could be done by an assistant. So that means that 18 minutes 23- 5 are actually productive for every patient that he sees. The first question asks us how many patients he sees on a typical day at work. Since he is at the clinic from eight A.M. to six P.M., he spends ten hours at work. However, two hours are spent on records, so that means he has 8 hours available to see patients. Thirty minute slots means means that he can see up to tw patients in one hour. So eight hours times two slots per hour means that he has 16 slots available to see patients per day. However, remember that not all of these slots are booked, 75% of slots are booked. So, 75% times 16 equals 12 slots that are booked per day. Finally, one out of every six patients who book an appointment doesn't show up. One out of six times twelve equals two. So that means Dr. Peters has two no shows per day. Twelve minus two is ten, which means Dr. Peters sees ten patients each day. The second question asks what his OPE is. Remember OPE is the amount of time the resource, in this case Dr. Peters is doing value added work, divided by the total amount of time the resource is available. First let's calculate the total number of minutes available for him to work each year. Two hundred and sixty days per year times ten hours per day times 60 minutes per hour Equals 156,000 minutes that are available for him to work each year. Now let's calculate how many minutes Doctor Peters does value added work. He spends 18 minutes of value-added time with every patient. And he sees ten patients per day for 230 days out of each year. So multiplying those together we get 41,400 minutes of value added work each year. Then our OPE is simply 41,400 divided by 156 Thousand which equals .2654.
