Cost Measurement Systems Traditional and Contemporary Approaches
Sam Houston State University ACC 564 R. Quarles Quarles, ACC 564, CMS
1
Cost Measurement Systems • Should not be confused with accounting • Do not address external reporting issues • Are based on the idea of being approximately correct rather than precisely wrong • Do not provide the answer • Are not dictated by a board of wise persons in Connecticut or by a bunch of clowns in Washington Quarles, ACC 564, CMS
2
Cost Measurement Systems • Cost measurement systems provide more questions and sometimes answers to questions related to strategic objectives of – Quality – Cost – Time
Quarles, ACC 564, CMS
3
Strategic Objectives • Quality – Features – Reliability • Costs involved – How much do features/reliability cost? – Can customers afford the level of quality provided? – How much does it cost to add new features or increase reliability? – How do we determine the cost of each feature or reliability element?
Quarles, ACC 564, CMS
4
Strategic Objectives • Cost – Must be measured in order to be managed – Related directly/indirectly to a product/service • Final reckoning - all costs incurred to provide product/services
– What causes costs? – Poor cost measurement may result in incorrectly leaving or remaining in a market – Cost system must identify, track, report costs of providing services or creating/delivering/supporting a product Quarles, ACC 564, CMS
5
Strategic Objectives • Time – Meeting delivery deadlines – Bringing product/service to market rapidly and proper point in time – Late delivery within the firm can delay other steps and increase costs – Altering process time schedules affects costs – Cost system must identify/measure time factors and costs of delays/alterations
Quarles, ACC 564, CMS
6
Attributes of a Good Cost System • Technical Attributes – Decision Relevance • Cost data related to strategic objectives – Cost of features/reliability – Identification of causes of cost for management attention
• Provide data for decision regarding – – – – –
Quarles, ACC 564, CMS
What customers/markets to target Product prices/profitability plans What products to promote Levels of quality/service to provide How manage costs/allocate resources
7
Attributes of a Good Cost System • Technical Attributes – Process Understanding • Help management understand work processes • Help management understand economic impact of activities that reduce/increase – Quality/Costs/Time
• Identifies costs across all steps in process - where are delays/cost multipliers • Identifies relationship between work done and cost incurred - ripple effect of activities in one area • Helps understand why work occurs and what drives costs Quarles, ACC 564, CMS
8
Attributes of a Good Cost System • Behavioral Attributes – Cost data • Increases visibility of activities • Focuses attention • Communicates managerial intent
– Cost structure visibility - highlights cost drivers • Decisions on products and processes affect costs • Cost data affects decision behaviors
– Communications with operations personnel • Non-accountants tolerate but do not understand • Bookkeeping versus working Quarles, ACC 564, CMS
9
Attributes of a Good Cost System • Behavioral Attributes – Employee Motivation • Cost data traditionally used to FIX BLAME – Leads to short-run decision emphasis – Cost data can be used to focus on how to work better, not who to blame
Quarles, ACC 564, CMS
10
Attributes of a Good Cost System • Cultural Attributes – Culture can emphasize blame or process improvement • Who spent the money versus is what is being done • Cross functional participation – Focus on cost objects reduces emphasis on departments – Activities necessary to produce cost cross departmental boundaries – Employees in different departments must work together to carry on activities
• Cost system should encourage process improvement and cross functional participation rather than fixing blame Quarles, ACC 564, CMS
11
Attributes of a Good Cost System • Improves strategic decisions by providing data on quality, cost, and time performance • Facilitates process management by providing data on the cost of the processes (activities and operations) used, and the underlying causal relationships (drivers) that cause costs to change. • Encourages behaviors consistent with strategic objectives • Creates mindsets and values that promote a healthy and positive organizational culture. Quarles, ACC 564, CMS
12
Nature of Cost Measurement Systems • Cost Measurement – Must exist separately from bookkeeping system • Emphasis on accountability for expenditures • Tracking of cost of resources PURCHASED as opposed to those USED
– Reorganizes data on resources acquired to provide strategic cost data • Not to be confused with accounting
Quarles, ACC 564, CMS
13
TYPICAL COST MEASUREMENT SYSTEM • Transformation engine that converts raw data on resources purchased into cost information about resources used Basic Cost Elements •Materials purchased •Wages and salaries •Utilities paid •Equipment purchases
The Building Blocks •Cost Objects •Cost flows/tracking procedures •Allocation rules
Output Strategic Cost Information •What products are most profitable? •What does each process step add to costs?
•Lease payments
•Which customers are profitable?
•Other expenditures
•What are the key cost drivers?
Quarles, ACC 564, CMS
14
Nature of Cost Measurement Systems • Building blocks of Cost Measurement – Cost Objects • Any item for which a measure of cost is desired – Products, customers, lines of business, markets, etc.
• Corresponds to strategic decision needs
– Tracking Procedures • Traditional Systems – Resources to Departments to Cost Objects
• Contemporary Systems – Resources to Activities to Cost Objects
Quarles, ACC 564, CMS
15
Nature of Cost Measurement Systems • Building blocks of Cost Measurement – Allocation Rules • Direct Costs – Cost of consumption of resources directly traceable to or assignable to a particular cost object » Direct labor Direct material
• Indirect Costs – Cannot be directly traced or directly attributable to a particular cost object – Must be allocated to cost objects in some consistent, logical, and informative manner
Quarles, ACC 564, CMS
16
Design of Cost Measurement Systems • Affects on Cost Systems – Mass Production • Substantial inventories leads to emphasis on inventory measurement and manufacturing product cost • Unskilled labor with authority vested in functional departmental manager - responsibility accounting – Responsibility center cost tracking
• Little product variety allows use of single allocation base for all indirect costs
Quarles, ACC 564, CMS
17
Traditional Cost Measurement • Two Approaches – Job Order and Process Costing • Job order appropriate where specific, unique jobs or batches can be identified – One of a kind or custom manufacturing
• Process costing appropriate for high volume of identical products using a continuous process – Oil refining, brewing, bread, cement, chemical manufacturing, etc.
– Resources • Period expenses: not associated with creating inventory • Product cost: creation of inventory Quarles, ACC 564, CMS
18
Job Order Costing • Resource cost traced to functional areas – Resources consumed by manufacturing area will be product costs – Cost centers – Costs within cost centers • Direct materials, direct labor, common costs
– Costs within the cost center traced to specific jobs or batches • Materials by requisition sheets • Direct labor by time cards • Others allocated based on some allocation basis Quarles, ACC 564, CMS

21
Process Costing • Products are not unique within a production run – Identical and therefore consume equal amounts of resources – Simple procedure is to determine costs of production runs and divide by number of units produced to determine cost per unit
Quarles, ACC 564, CMS
22
Process Costing • Complicating factor – Work in process • Beginning and ending WIP in various stages of completion • Completion as to % of cost incurrence • WIP at end of period is come % complete as to the total cost that will be incurred in its completion • Equivalent Units of Production
Quarles, ACC 564, CMS
23
Process Costing Calculation of EUP (weighted average) Units completed and transferred 1,000,000 Ending WIP 40,000 units 60% complete 24,000 __________ Equivalent Units Produced
1,024,000
Cost incurred / EUP = Cost per unit Quarles, ACC 564, CMS
24
TRADITIONAL COST SYSTEMS • Reflect a management philosophy of: – Responsibility by departments or cost centers – Financial rather than operational control – After-the-fact cost control rather than cost planning • Primary focus – Manufacturing costs (same as product cost) – Inventory and labor reporting • Cost flows from department to products Quarles, ACC 564, CMS
25
Traditional Systems • Weaknesses – Product cost is not the total cost of the product • Manufacturing cost only • Ignores design,creation, installation,service, etc.
– Indirect cost (overhead) significant element of total cost but no data provided of what causes these costs in relation to particular products or volumes or processes
Quarles, ACC 564, CMS
26
Cost Measurement Systems • New concepts affecting systems – TQM • Cross functional management of processes reduce emphasis on responsibility accounting
– Lean Manufacturing or TQM • Reduces/eliminates inventory issues
– World Class Competition • Identify and manage costs, not purchases
– Total Product Cost • Manufacturing cost plus all costs of getting product/service to customer Quarles, ACC 564, CMS
27
Activity Based Costing – Emphasis on activities and their relationships to resources and cost objects
• Steps in ABC • Step 1: identify activities and objects used by jobs/processes • Process map • Activities are related tasks that are accomplished in order to do what the work
Quarles, ACC 564, CMS
28
Activity Based Costing • Step 2: compute the cost of activities Exhibit 12: Activity Cost for Heat Exchangers Activity or Ope ration Cost Visit prospective customers $ 83,600 Develop product specifications 608,000 Draft contract 270,000 Purchase materials 288,000 Set up stamping machines 1,176,000 Stamp steel plates 3,952,000 Build frame 756,000 Insert plates into frames 5,040,000 Attach cover 126,000 Move unit to paint shop 9,000 Paint 480,000 Test 770,000 Transport to customer site 910,000 Final assembly 702,000 Final inspection 504,000 Bill customer 8,400 Other activities 87,000 Total Activity Cost $ 15,770,000 Quarles, ACC 564, CMS
29
Activity Based Costing • Step 3: determine cost drivers for each activity – Cost drivers • (activity usage drivers) must be identified • what causes the activities to cost what they do

Activity Based Costing
• Step 4: create cost pools for common drivers – Simplify calculations and emphasizes drivers that account for significant costs
Quarles, ACC 564, CMS
