Compute the throughput time. (Round your answer to 1 decimal place.) 2. Compute the manufacturing cycle efficiency (MCE) for the quarter. (Round your percentage answer to nearest whole percent.) 3. What percentage of the throughput time was spent in non-value-added activities? (Round your percentage answer to nearest whole percent.) 4. Compute the delivery cycle time. (Round your intermediate calculations and final answer to 1 decimal place.) 5. If by using Lean Production all queue time during production is eliminated, what will be the new MCE?

Refer to the information for Farnsworth Company (p. 139) for the first 10 months of data on receiving orders and receiving cost. Now suppose that Tracy has gathered 2 more months of data: Note: For the following requirements, round the intercept terms to the nearest dollar, round the variable rates to the nearest cent, and R2 to two decimal places. Required: 1. Run two regressions using a computer spreadsheet program such as Excel. First, use the method of least squares on the first 10 months of data. Then, use the method of least squares on all 12 months of data. Write down the results for the intercept, slope, and R2 for each regression. Compare the results. 2. CONCEPTUAL CONNECTION Prepare a scattergraph using all 12 months of data. Do any points appear to be outliers? Suppose Tracy has learned that the factory suffered severe storm damage during Month 11 that required extensive repairs to the receiving areaincluding major repairs on a forklift. These expenses, included in Month 11 receiving costs, are not expected to recur. What step might Tracy, using her judgment, take to amend the results from the method of least squares? 3. CONCEPTUAL CONNECTION Rerun the method of least squares, using all the data except for Month 11. (You should now have 11 months of data.) Prepare a cost formula for receiving based on these results, and calculate the predicted receiving cost for a month with 1,450 receiving orders. Discuss the results from this regression versus those from the regression for 12 months of data.
Ethics in Action In August, Lannister Company introduced a new performance measurement system in manufacturing operations. One of the new performance measures is lead time, which is determined by tagging a random sample of items with a log sheet throughout the month. The log sheets recorded the time that the sample items started production and the time that they ended production, as well as all steps in between. At the end of the month, the controller collected the log sheets and computed the average lead time of the tagged products. This number was reported to central management and was used to evaluate the performance of the plant manager. Because of the poor lead time results reported for August, the plant was under extreme pressure to reduce lead time in September. The following memo was intercepted by the controller. Date: September 3 To: Hourly Employees From: Plant Manager During last month, you may have noticed that some of the products were tagged with a log sheet. This sheet records the time that a product enters production and the time that it leaves production. The difference between these two times is termed the lead time. Our plant is evaluated on improving lead time. From now on, I ask all of you to keep an eye out for the tagged items. When you see a tagged item, it is to receive special attention. Work on that item first, and then immediately move it to the next operation. Under no circumstances should tagged items wait on any other work that you have. Naturally, report accurate information. I insist that you record the correct times on the log sheet as the product goes through your operations. How should the controller respond to this discovery?
If the factory overhead control account has a credit balance of 2,000 at the end of the first month of the fiscal year, has the overhead been under- or overapplied for the month? What are some probable causes for the credit balance?
Scattergraph, High-Low Method, and Predicting Cost for a Different Time Period from the One Used to Develop a Cost Formula Refer to the information for Farnsworth Company on the previous page. Required: 1. Prepare a scattergraph based on the 10 months of data. Does the relationship appear to be linear? 2. Using the high-low method, prepare a cost formula for the receiving activity. Using this formula, what is the predicted cost of receiving for a month in which 1,450 receiving orders are processed? 3. Prepare a cost formula for the receiving activity for a quarter. Based on this formula, what is the predicted cost of receiving for a quarter in which 4,650 receiving orders are anticipated? Prepare a cost formula for the receiving activity for a year. Based on this formula, what is the predicted cost of receiving for a year in which 18,000 receiving orders are anticipated? Use the following information for Problems 3-60 and 3-61: Farnsworth Company has gathered data on its overhead activities and associated costs for the past 10 months. Tracy Heppler, a member of the controllers department, has convinced management that overhead costs can be better estimated and controlled if the fixed and variable components of each overhead activity are known. One such activity is receiving raw materials (unloading incoming goods, counting goods, and inspecting goods), which she believes is driven by the number of receiving orders. Ten months of data have been gathered for the receiving activity and are as follows:
