Production Cycle Activities
Accurate and timely cost accounting information is essential input to decisions about:
• Product mix • Product pricing• Resource allocation and planning • Cost management
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-10
Production Cycle Activities
There are four basic activities in the production cycle:
1. Product design
2. Planning and scheduling
3. Production operations
4. Cost accounting
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-11
Product Design (Activity 1)
The first step in the production cycle is product design.
The objective of this activity is to design a product that meets customer requirements for quality, durability, and functionality while simultaneously minimizing production costs.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-12
Product Design (Activity 1)
Documents and procedures: The product design activity creates
two main documents:1 Bill of materials2 Operations list
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-13
Product Design (Activity 1) How can accountants be involved in product
design?– by showing how various design trade-offs
affect production costs and thereby profitability
– by ensuring that the AIS is designed to collect and provide information about the machine setup and materials handling costs associated with alternative product designs
– by providing data about repair and warranty costs associated with existing products
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-14
Planning and Scheduling (Activity 2)
The second step in the production cycle is planning and scheduling.
The objective of this step is a production plan efficient enough to meet existing orders and anticipate short-term demand without creating excess finished goods inventories.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-15
Planning and Scheduling (Activity 2)
What are two common methods of production planning?1 Manufacturing resource planning (MRP-II)2 Just-in-time (JIT) manufacturing systems
• MRP-II is an extension of materials resource planning that seeks to match existing production capacity and raw materials needs with forecasted sales demands.
• The goal of JIT is to minimize inventories of raw materials, work in process, and finished goods.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-16
Planning and Scheduling (Activity 2) Documents, forms and procedures:
The master production schedule (MPS) specifies how much of each product is to be produced during the planning period and when that production should occur.
A materials requisition authorizes removal of materials from the storeroom to the factory.
Subsequent transfers of these materials are documented on move tickets.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-17
Planning and Scheduling (Activity 2) How can accountants be involved in
planning and scheduling?– by ensuring that the AIS collects and
reports costs in a manner consistent with the production planning techniques used by the company
– by helping to choose whether MRP-II or JIT is more appropriate
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-18
Production Operations (Activity 3) The third step in the production cycle
is the actual manufacture of products. The manner in which this activity is
accomplished varies greatly across companies.
What is computer-integrated manufacturing (CIM)?It is the use of information technology
in the production process.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-19
Production Operations (Activity 3) Computer-Integrated Manufacturing (CIM) is the use
of various forms of IT in the production process, such as robots and computer-controlled machinery, to reduce production costs.
Every firm needs to collect data about the following four facets of its production operations:
1. Raw materials used2. Labor-hours expended3. Machine operations performed4. Other manufacturing overhead costs incurred
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-20
Learning Objective 2
Explain how a company’s cost accounting system can help it achieve its manufacturing goals
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-21
Cost Accounting (Activity 4) The final step in the production cycle is
cost accounting. What are the three principal objectives of
the cost accounting system?1. To provide information for planning,
controlling, and evaluating the performance of production operations
2. To provide accurate cost data about products for use in pricing and product mix decisions
3. To collect and process the information used to calculate the inventory and cost of goods sold values
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-22
Cost Accounting (Activity 4)
What are two types of cost accounting systems?1 Job-order costing2 Process costing Job-order costing assigns costs to specific
production batches or to individual jobs. Process costing assigns costs to each
process, and then calculates the average cost for all units produced.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-23
Cost Accounting (Activity 4)
The choice of job-order or process costing affects only the method used to assign costs to products, not the method used for data collection.
Raw Materials:When production is initiated, the
issuance of a materials requisition triggers the journal entry.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-24
Cost Accounting (Activity 4)
Assume that $15,000 of raw materials were issued.
What is the journal entry?Work in Process 15,000
Raw Materials Inventory
15,000 To record issuance of raw materials
Assume that $1,000 of raw materials were returned to inventory.

13-25
Cost Accounting (Activity 4)
What is the journal entry?Raw Materials Inventory
1,000 Work in Process 1,000 To record return of raw materials to inventory
Most raw materials are bar-coded. Inventory clerks use online terminals
to enter usage data for those items that are not bar-coded.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-26
Cost Accounting (Activity 4)
Direct Labor: A job-time ticket is a paper document used
to collect data about labor activity. This document records the amount of time a
worker spent on each specific job task. Workers can enter this data using online
terminals at each factory workstation.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-27
Cost Accounting (Activity 4)
Machinery and Equipment:
As companies implement CIM to automate the production process, an even larger proportion of product cost relate to the machinery and equipment used to make the product.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-28
Cost Accounting (Activity 4)
Manufacturing Overhead: What is manufacturing overhead?
– all manufacturing costs that are not economically feasible to trace directly to specific jobs or processes
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-29
Cost Accounting (Activity 4)
Accounting for Fixed Assets: The AIS also needs to collect and
process information about investment in the property, plant, and equipment used in the production cycle.
Fixed assets should be bar-coded.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-30
Cost Accounting (Activity 4)
– identification number– serial number– location– cost– date of acquisition– vendor name and
address– expected life
– expected salvage value
– depreciation method– depreciation charges
to date– improvements– maintenance services
performed
What minimum information should organizations keep about their fixed assets?

13-31
Learning Objective 3
Identify major threats in the production cycle, and evaluate the adequacy of various control procedures for dealing with them.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-32
Control: Objectives,Threats, and Procedures The second function of a well-designed
AIS is to provide adequate controls to ensure that the following objectives are met:1. All production and fixed asset acquisitions
are properly authorized.
2. Work-in-process inventories and fixed assets are safeguarded.
3. All valid, authorized production cycle transactions are recorded.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-33
Control: Objectives,Threats, and Procedures
4. All production cycle transactions are recorded accurately.
5. Accurate records are maintained and protected from loss.
6. Production cycle activities are performed efficiently and effectively.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-34
Control: Objectives,Threats, and Procedures
What are some threats?– unauthorized transaction– theft or destruction of inventories and
fixed assets– recording and posting errors– loss of data– inefficiencies and quality control
problems
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-35
Control: Objectives,Threats, and Procedures What are some control procedures?
– accurate sales forecasts and inventory records
– authorization of production– restricted access to production
planning program and to blank production order documents
– review and approval of capital asset expenditures
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-36
Control: Objectives,Threats, and Procedures
– documentation of all internal movements of inventory
– proper segregation of duties– source data automation– online data entry edit controls– backup and disaster recovery
procedures– regular performance reports– cost of quality control measurement
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-37
Learning Objective 4
Discuss the key decisions that must be made in the production cycle, and identify the information required to make those decisions.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-38
Information Needs and Procedures The third function of the AIS is to provide
information useful for decision making. In the production cycle, cost information is
needed by internal and external users. Traditionally, most cost accounting systems
have been designed primarily to meet financial reporting requirements.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-39
Information Needs and Procedures
What are two major criticisms of traditional cost accounting systems?
1. Inappropriate allocation of overhead costs
2. Inaccurate performance measures
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-40
Information Needs and Procedures
What is a potential solution to the first criticism?
Activity-Based Costing (ABC):ABC attempts to trace costs to the
activities that create them and only subsequently allocates those costs to products or departments.
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-41
Information Needs and Procedures ABC systems distinguish three separate
categories of overhead.1. Batch-related overhead2. Product-related overhead3. Company-wide overhead
The bases used to allocate manufacturing overhead are the cost drivers.
What is a cost driver?– anything that has a cause-and-effect
relationship on costs
©2003 Prentice Hall Business Publishing, Accounting Information Systems, 9/e, Romney/Steinbart
13-42
Information Needs and Procedures What are some benefits of ABC?
– better decisions– improved cost management
More accurate cost data results in better product mix and pricing decisions.
More detailed cost data improves management’s ability to control and manage total costs.

13-43
Information Needs and Procedures
What is the potential solution to the second criticism?– Integrated production cycle data

13-45
Production Cycle Data Model To maximize its usefulness for cost
management and decision making, production cycle data must be collected at the lowest possible level of aggregation.
The following diagram presents relationships between the work in process (resource entity) and raw materials, labor, and machine operations (event entities) used to produce a batch of goods.

Production Cycle Data Model What are the relationships among work in
process and the three event entities?– all are one-to-many
What do they reflect? Each production run may involve a number
of raw materials issuances, labor operations, and machine operations.
Each of those activities, however, is linked to a specific production run.

Case Conclusion
What did Elizabeth Venko decide?– Implement activity-based costing– Change the reports produced
She decided that two major changes were needed in the reports produced by the AIS:1 Quality control costs will be reported.2 Nonfinancial as well as financial measures
will be included in the performance reports.
