lakt time measure which b. I Discussion Questions ( Why Is It portant to look a formance, as measured by average Inventory avera e gate flow pe flow time, and average throughput? 3.2 Discuss why it is often easier to measure average inventory and average throughput rather than aver- age flow time How can a manager determine the minimal set of operational measures that should be tracked on a daily basis to predict the financial performances of a process? The Internal Revenue's Department of Tax Regulations writes regulations in accordance with laws passed by Congress. On average, the department completes 300 projects per year. The Wall Street Journal reports that, as of October 11, 2011, the number of projects.currently "on the department's plate" is 588. Nevertheless, the department head claims that average time to complete a project is less than six months. Do you have any rea- son to disagree? Why or why not? The Wall Street Journal reported that although GM and Toyota are operating with the same number of inventory turns, Toyota's throughput is twice that of GM." The discrepancy, concluded the writer, could be due to much faster flow times and lower invento- Exercises C3.1 A bank finds that the average number of people wait- ing in line during lunch hour is 10. On average, dur- ing this period, 2 people per minute leave the bank after receiving service. On average, how long do bank customers wait in line? 3.2 At the drive-through counter of a fast-food outlet, an average of 10 cars waits in line. The manager wants to determine if the length of the line is having any impact on potential sales. A study reveals that, on average, 2 cars per minute try to enter the drive- through area, but 25 percent of the drivers of these cars are dismayed by the long line and simply move on without placing orders. Assume that no car that

The two statements are inconsistent. If both have the same inventory turns, they have the same flow time but Toyota has lower average inventory than GM. d. The two statements are inconsistent: If both have the same inventory turns, they have the same aver- age inventory; but Toyota has higher flow time than GM. e. The two statements are inconsistent: if both have the same inventory turns, they have the same average inventory; but Toyota has lower flow time than GM 3.6 is there a difference between low inventories and fast inventory turnover? 37 Is there a difference between flow time and takt time?

Checking accounts at a local bank carry an average balance of \$3,000. The bank turns over its balance 6 times a year. On average how many dollars flow Through the bank each month? A hospital emergency room (ER) is currently organ- ized so that all patients register through an initial check-in process. At his or her turn, each patient is seen by a doctor and then exits the process, either with a prescription or with admission to the hospi- tal. Currently, 55 people per hour arrive at the ER 10 percent of who are admitted to the hospital. On these move

Assume the process to be stable that is, average inflow rate equals average outflow rate. 3.5 triage system has been proposed for the ER described in Exercise 34 Under the proposed triage plan, entering patients will be registered as before They will then be quickly examined by a une practi- tioner who will classify them as Sungle Triptions or Potential Admits Wule Simple l'escruptions will move on to an area staffed for regular cane Potential Admits will be taken to the emergency area Tanner anticipate that the initial examination will take 3 -> utes. They expect that, on average, 20 patients wmbe wanting to register and 5 will be waiting to be seen by the triage nurse Recall that registration takes an aver age of 2 minutes per patient. The triage nurse is expected to take an average of 1 minute per patient Planners expect the Simple Prescriptions area to have, on average, 15 patients waiting to be seer. As before, once a patient's turn comes, each will take 5 minutes of a doctor's time. The hospital anticipates that on average the emergency arca will have only patient waiting to be seen. As before, once that patient's tum comes, he or she will take 30 minutes of a doctor's time. Assume that, as before, 90 percent of all patients are Simple Prescriptions: Assume, too, that the triage nurse is 100 percent accurate in making classificay tions.

On aver age, how many patients will be in the LR2 Assume the process to be stable that is, average inflow rate equalt average outflow rate. Refer to Exercise 35. Once the triage system is put in place, it performs quite close to expectations. All data conform to planners' expectations except for one set the classifications made by the nurse practi- tioner. Assume that the triage nurse has been sending 91 percent of all patients to the Simple Prescription area when in fact only 90 percent should have been so classified. The remaining 1 percent is discovered when transferred to the emergency area by a doctor. Assume all other information from Exercise 3.5 to be valid. On average, how long does a patient spend in the ER? On average, how long does a Potential Admit spend in the ER? On average, how many patients are in the ER? Assume the process to be stable that is average inflow rate equals average outflow rate.

Q.3.7 Is their any difference Between Flow time and take time

 Point of Difference Flow Time Takt time Meaning The amount of time a flow unit spends in a business process from beginning to end, also known as the total processing time. If there is more than one path through the process, the flow time is equivalent to the length of the longest path. Takt Time is a customer demand calculation that tells you how often a part should be completed by a particular process in order to meet demand. Total time It is actually the time taken by the unit to get produced.it is also called the total process time. Takt time is the maximum amount of time in which a product needs to be produced in order to satisfy customer demand.
