Joseph Fox, controller of Thorpe Company, has been in charge of a project to install an activity-based cost management system. This new system is designed to support the company’s efforts to become more competitive. For the past six weeks, he and the project committee members have been identifying and defining activities, associating workers with activities, and assessing the time and resources consumed by individual activities. Now, he and the project committee are focusing on three additional implementation issues: (1) identifying activity drivers, (2) assessing value content, and (3) identifying cost drivers (root causes). Joseph has assigned a committee member the responsibilities of assessing the value content of five activities, choosing a suitable activity driver for each activity, and identifying the possible root causes of the activities. Following are the five activities with possible activity drivers: The committee member ran a regression analysis for each potential activity driver, using the method of least squares to estimate the variable and fixed cost components. In all five cases, costs were highly correlated with the potential drivers. Thus, all drivers appeared to be good candidates for assigning costs to products. The company plans to reward production managers for reducing product costs. Required: 1. What is the difference between an activity driver and a cost driver? In answering the question, describe the purpose of each type of driver. 2. For each activity, assess the value content and classify each activity as value-added or non-value-added (justify the classification). Identify some possible root causes of each activity, and describe how this knowledge can be used to improve activity performance. For purposes of discussion, assume that the value-added activities are not performed with perfect efficiency. 3. Describe the behavior that each activity driver will encourage, and evaluate the suitability of that behavior for the company’s objective of becoming more competitive.

Randy Harris, controller, has been given the charge to implement an advanced cost management system. As part of this process, he needs to identify activity drivers for the activities of the firm. During the past four months, Randy has spent considerable effort identifying activities, their associated costs, and possible drivers for the activities costs. Initially, Randy made his selections based on his own judgment using his experience and input from employees who perform the activities. Later, he used regression analysis to confirm his judgment. Randy prefers to use one driver per activity, provided that an R2 of at least 80 percent can be produced. Otherwise, multiple drivers will be used, based on evidence provided by multiple regression analysis. For example, the activity of inspecting finished goods produced an R2 of less than 80 percent for any single activity driver. Randy believes, however, that a satisfactory cost formula can be developed using two activity drivers: the number of batches and the number of inspection hours. Data collected for a 14-month period are as follows: Required: 1. Calculate the cost formula for inspection costs using the two drivers, inspection hours and number of batches. Are both activity drivers useful? What does the R2 indicate about the formula? 2. Using the formula developed in Requirement 1, calculate the inspection cost when 300 inspection hours are used and 30 batches are produced. Prepare a 90 percent confidence interval for this prediction.

Tom Young, vice president of Dunn Company (a producer of plastic products), has been supervising the implementation of an activity-based cost management system. One of Toms objectives is to improve process efficiency by improving the activities that define the processes. To illustrate the potential of the new system to the president, Tom has decided to focus on two processes: production and customer service. Within each process, one activity will be selected for improvement: molding for production and sustaining engineering for customer service. (Sustaining engineers are responsible for redesigning products based on customer needs and feedback.) Value-added standards are identified for each activity. For molding, the value-added standard calls for nine pounds per mold. (Although the products differ in shape and function, their size, as measured by weight, is uniform.) The value-added standard is based on the elimination of all waste due to defective molds (materials is by far the major cost for the molding activity). The standard price for molding is 15 per pound. For sustaining engineering, the standard is 60 percent of current practical activity capacity. This standard is based on the fact that about 40 percent of the complaints have to do with design features that could have been avoided or anticipated by the company. Current practical capacity (the first year) is defined by the following requirements: 18,000 engineering hours for each product group that has been on the market or in development for five years or less, and 7,200 hours per product group of more than five years. Four product groups have less than five years experience, and 10 product groups have more. There are 72 engineers, each paid a salary of 70,000. Each engineer can provide 2,000 hours of service per year. There are no other significant costs for the engineering activity. For the first year, actual pounds used for molding were 25 percent above the level called for by the value-added standard; engineering usage was 138,000 hours. There were 240,000 units of output produced. Tom and the operational managers have selected some improvement measures that promise to reduce non-value-added activity usage by 30 percent in the second year. Selected actual results achieved for the second year are as follows: The actual prices paid per pound and per engineering hour are identical to the standard or budgeted prices. Required: 1. For the first year, calculate the non-value-added usage and costs for molding and sustaining engineering. Also, calculate the cost of unused capacity for the engineering activity. 2. Using the targeted reduction, establish kaizen standards for molding and engineering (for the second year). 3. Using the kaizen standards prepared in Requirement 2, compute the second-year usage variances, expressed in both physical and financial measures, for molding and engineering. (For engineering, explain why it is necessary to compare actual resource usage with the kaizen standard.) Comment on the companys ability to achieve its targeted reductions. In particular, discuss what measures the company must take to capture any realized reductions in resource usage.

John Thomas, vice president of Mallett Company (a producer of a variety of plastic products), has been supervising the implementation of an ABC management system. John wants to improve process efficiency by improving the activities that define the processes. To illustrate the potential of the new system to the president, John has decided to focus on two processes: production and customer service. Within each process, one activity will be selected for improvement: materials usage for production and sustaining engineering for customer service (sustaining engineers are responsible for redesigning products based on customer needs and feedback). Value-added standards are identified for each activity. For materials usage, the value-added standard calls for six pounds per unit of output (the products differ in shape and function, but their weight is uniform). The value-added standard is based on the elimination of all waste due to defective molds. The standard price of materials is 5 per pound. For sustaining engineering, the standard is 58% of current practical activity capacity. This standard is based on the fact that about 42% of the complaints have to do with design features that could have been avoided or anticipated by the company. Current practical capacity (at the end of 20X1) is defined by the following requirements: 6,000 engineering hours for each product group that has been on the market or in development for 5 years or less and 2,400 hours per product group of more than 5 years. Four product groups have less than 5 years experience, and 10 product groups have more. Each of the 24 engineers is paid a salary of 60,000. Each engineer can provide 2,000 hours of service per year. No other significant costs are incurred for the engineering activity. Actual materials usage for 20X1 was 25% above the level called for by the value-added standard; engineering usage was 46,000 hours. A total of 80,000 units of output were produced. John and the operational managers have selected some improvement measures that promise to reduce nonvalue-added activity usage by 40% in 20X2. Selected actual results achieved for 20X2 are as follows: The actual prices paid for materials and engineering hours are identical to the standard or budgeted prices. Required: 1. For 20X1, calculate the nonvalue-added usage and costs for materials usage and sustaining engineering. 2. CONCEPTUAL CONNECTION Using the budgeted improvements, calculate the expected activity usage levels for 20X2. Now, compute the 20X2 usage variances (the difference between the expected and actual values), expressed in both physical and financial measures, for materials and engineering. Comment on the companys ability to achieve its targeted reductions. In particular, discuss what measures the company must take to capture any realized reductions in resource usage.

Kagle design engineers are in the process of developing a new green product, one that will significantly reduce impact on the environment and yet still provide the desired customer functionality. Currently, two designs are being considered. The manager of Kagle has told the engineers that the cost for the new product cannot exceed 550 per unit (target cost). In the past, the Cost Accounting Department has given estimated costs using a unit-based system. At the request of the Engineering Department, Cost Accounting is providing both unit-and activity-based accounting information (made possible by a recent pilot study producing the activity-based data). Unit-based system: Variable conversion activity rate: 100 per direct labor hour Material usage rate: 20 per part ABC system: Labor usage: 15 per direct labor hour Material usage (direct materials): 20 per part Machining: 75 per machine hour Purchasing activity: 150 per purchase order Setup activity: 3,000 per setup hour Warranty activity: 500 per returned unit (usually requires extensive rework) Customer repair cost: 25 per repair hour (average) Required: 1. Select the lower-cost design using unit-based costing. Are logistical and post-purchase activities considered in this analysis? 2. Select the lower-cost design using ABC analysis. Explain why the analysis differs from the unit-based analysis. 3. What if the post-purchase cost was an environmental contaminant and amounted to 10 per unit for Design A and 40 per unit for Design B? Assume that the environmental cost is borne by society. Now which is the better design?

Big Mikes, a large hardware store, has gathered data on its overhead activities and associated costs for the past 10 months. Nizam Sanjay, a member of the controllers department, believes that overhead activities and costs should be classified into groups that have the same driver. He has decided that unloading incoming goods, counting goods, and inspecting goods can be grouped together as a more general receiving activity, since these three activities are all driven by the number of receiving orders. The 10 months of data shown below have been gathered for the receiving activity. Required: 1. Prepare a scattergraph, plotting the receiving costs against the number of purchase orders. Use the vertical axis for costs and the horizontal axis for orders. 2. Select two points that make the best fit, and compute a cost formula for receiving costs. 3. Using the high-low method, prepare a cost formula for the receiving activity. 4. Using the method of least squares, prepare a cost formula for the receiving activity. What is the coefficient of determination?

The management of Wheeler Company has decided to develop cost formulas for its major overhead activities. Wheeler uses a highly automated manufacturing process, and power costs are a significant manufacturing cost. Cost analysts have decided that power costs are mixed; thus, they must be broken into their fixed and variable elements so that the cost behavior of the power usage activity can be properly described. Machine hours have been selected as the activity driver for power costs. The following data for the past eight quarters have been collected: Required: 1. Prepare a scattergraph by plotting power costs against machine hours. Does the scatter-graph show a linear relationship between machine hours and power cost? 2. Using the high and low points, compute a power cost formula. 3. Use the method of least squares to compute a power cost formula. Evaluate the coefficient of determination. 4. Rerun the regression and drop the point (20,000; 26,000) as an outlier. Compare the results from this regression to those for the regression in Requirement 3. Which is better?

Jolene Askew, manager of Feagan Company, has committed her company to a strategically sound cost reduction program. Emphasizing life-cycle cost management is a major part of this effort. Jolene is convinced that production costs can be reduced by paying more attention to the relationships between design and manufacturing. Design engineers need to know what causes manufacturing costs. She instructed her controller to develop a manufacturing cost formula for a newly proposed product. Marketing had already projected sales of 25,000 units for the new product. (The life cycle was estimated to be 18 months. The company expected to have 50 percent of the market and priced its product to achieve this goal.) The projected selling price was 20 per unit. The following cost formula was developed: Y=200,000+10X1 where X1=Machinehours(Theproductisexpectedtouseonemachinehourforeveryunitproduced.) Upon seeing the cost formula, Jolene quickly calculated the projected gross profit to be 50,000. This produced a gross profit of 2 per unit, well below the targeted gross profit of 4 per unit. Jolene then sent a memo to the Engineering Department, instructing them to search for a new design that would lower the costs of production by at least 50,000 so that the target profit could be met. Within two days, the Engineering Department proposed a new design that would reduce unit-variable cost from 10 per machine hour to 8 per machine hour (Design Z). The chief engineer, upon reviewing the design, questioned the validity of the controllers cost formula. He suggested a more careful assessment of the proposed designs effect on activities other than machining. Based on this suggestion, the following revised cost formula was developed. This cost formula reflected the cost relationships of the most recent design (Design Z). Y=140,000+8X1+5,000X2+2,000X3 where X1=MachinehoursX2=NumberofbatchesX3=Numberofengineeringchangeorders Based on scheduling and inventory considerations, the product would be produced in batches of 1,000; thus, 25 batches would be needed over the products life cycle. Furthermore, based on past experience, the product would likely generate about 20 engineering change orders. This new insight into the linkage of the product with its underlying activities led to a different design (Design W). This second design also lowered the unit-level cost by 2 per unit but decreased the number of design support requirements from 20 orders to 10 orders. Attention was also given to the setup activity, and the design engineer assigned to the product created a design that reduced setup time and lowered variable setup costs from 5,000 to 3,000 per setup. Furthermore, Design W also creates excess activity capacity for the setup activity, and resource spending for setup activity capacity can be decreased by 40,000, reducing the fixed cost component in the equation by this amount. Design W was recommended and accepted. As prototypes of the design were tested, an additional benefit emerged. Based on test results, the post-purchase costs dropped from an estimated 0.70 per unit sold to 0.40 per unit sold. Using this information, the Marketing Department revised the projected market share upward from 50 percent to 60 percent (with no price decrease). Required: 1. Calculate the expected gross profit per unit for Design Z using the controllers original cost formula. According to this outcome, does Design Z reach the targeted unit profit? Repeat, using the engineers revised cost formula. Explain why Design Z failed to meet the targeted profit. What does this say about the use of unit-based costing for life-cycle cost management? 2. Calculate the expected profit per unit using Design W. Comment on the value of activity information for life-cycle cost management. 3. The benefit of the post-purchase cost reduction of Design W was discovered in testing. What direct benefit did it create for Feagan Company (in dollars)? Reducing post-purchase costs was not a specific design objective. Should it have been? Are there any other design objectives that should have been considered?

Anderson Company has the following departmental manufacturing structure for one of its products: After some study, the production manager of Anderson recommended the following revised cellular manufacturing approach: Required: 1. Calculate the total time it takes to produce a batch of 20 units using Andersons traditional departmental structure. 2. Using cellular manufacturing, how much time is saved producing the same batch of 20 units? Assuming the cell operates continuously, what is the production rate? Which process controls this production rate? 3. What if the processing times of molding, welding, and assembly are all reduced to six minutes each? What is the production rate now, and how long will it take to produce a batch of 20 units?

Jane Erickson, manager of an electronics division, was not pleased with the results that had recently been reported concerning the divisions activity-based management implementation project. For one thing, the project had taken eight months longer than projected and had exceeded the budget by nearly 35 percent. But even more vexatious was the fact that after all was said and done, about three-fourths of the plants were reporting that the activity-based product costs were not much different for most of the products than those of the old costing system. Plant managers were indicating that they were continuing to use the old costs as they were easier to compute and understand. Yet, at the same time, they were complaining that they were having a hard time meeting the bids of competitors. Reliable sources were also revealing that the divisions product costs were higher than many competitors. This outcome perplexed plant managers because their control system still continued to report favorable materials and labor efficiency variances. They complained that ABM had failed to produce any significant improvement in cost performance. Jane decided to tour several of the plants and talk with the plant managers. After the tour, she realized that her managers did not understand the concept of non-value-added costs nor did they have a good grasp of the concept of kaizen costing. No efforts were being made to carefully consider the activity information that had been produced. One typical plant manager threw up his hands and said: This is too much data. Why should I care about all this detail? I do not see how this can help me improve my plants performance. They tell me that inspection is not a necessary activity and does not add value. I simply cant believe that inspecting isnt value-added and necessary. If we did not inspect, we would be making and sending more bad products to customers. Required: Explain why Janes division is having problems with its ABM implementation.

Two departments within Cougar Gear Inc. are Production and Sales. Each department has a unique scorecard, as follows: The Production Department scorecard focuses on the learning and growth and internal processes perspectives. The Sales Department scorecard focuses on the learning and growth and customer perspectives. Both scorecards have the learning and growth performance metrics of median training hours per employee and average employee tenure. The Production scorecard has the unique metrics of production time per unit and number of production shutdowns. The Sales scorecard has the unique metrics of percentage of customers who shop again and online customer satisfaction rating. The performance targets for each metric are shown in the tan boxes just under the performance metrics. The actual achieved metrics are shown in the red boxes just below the tan boxes. When evaluating both departments, Cougar Gears management looks at the median training hours per employee and average employee tenure metrics and subsequently decides to give the Sales Department a large bonus while giving the Production Department a minimal bonus. a. Determine and define the type of cognitive bias Cougar Gears management has exhibited in this instance. b. Determine which department would have received the larger bonus had the companys management not been biased in the evaluation. c. Discuss one advantage and one disadvantage of using unique balanced scorecards for different departments or divisions of a company.

Mott Company recently implemented a JIT manufacturing system. After one year of operation, Heidi Burrows, president of the company, wanted to compare product cost under the JIT system with product cost under the old system. Motts two products are weed eaters and lawn edgers. The unit prime costs under the old system are as follows: Under the old manufacturing system, the company operated three service centers and two production departments. Overhead was applied using departmental overhead rates. The direct overhead costs associated with each department for the year preceding the installation of JIT are as follows: Under the old system, the overhead costs of the service departments were allocated directly to the producing departments and then to the products passing through them. (Both products passed through each producing department.) The overhead rate for the Machining Department was based on machine hours, and the overhead rate for assembly was based on direct labor hours. During the last year of operations for the old system, the Machining Department used 80,000 machine hours, and the Assembly Department used 20,000 direct labor hours. Each weed eater required 1.0 machine hour in Machining and 0.25 direct labor hour in Assembly. Each lawn edger required 2.0 machine hours in Machining and 0.5 hour in Assembly. Bases for allocation of the service costs are as follows: Upon implementing JIT, a manufacturing cell for each product was created to replace the departmental structure. Each cell occupied 40,000 square feet. Maintenance and materials handling were both decentralized to the cell level. Essentially, cell workers were trained to operate the machines in each cell, assemble the components, maintain the machines, and move the partially completed units from one point to the next within the cell. During the first year of the JIT system, the company produced and sold 20,000 weed eaters and 30,000 lawn edgers. This output was identical to that for the last year of operations under the old system. The following costs have been assigned to the manufacturing cells: Required: 1. Compute the unit cost for each product under the old manufacturing system. 2. Compute the unit cost for each product under the JIT system. 3. Which of the unit costs is more accurate? Explain. Include in your explanation a discussion of how the computational approaches differ. 4. Calculate the decrease in overhead costs under JIT, and provide some possible reasons that explain the decrease.

In 20x2, Choctaw Company implements a new process affecting labor and materials. The following reported data are provided to evaluate the effect on the companys productivity: Required: 1. Calculate the productivity profile for 20x1. 2. Calculate the productivity profile for 20x2, and comment on the effect of the new production and assembly process. 3. What if the labor hours used in 20x2 were 112,500? What does comparison of the 20x1 and 20x2 profiles now communicate?
