Once you have completed this chapter, you should be able to:

Objective 1

Explain the difference between strategic and operational decisions and how accounting information supports these decisions.

2

The New Competitive Environment

3

The Japanese automobile industry generally is given credit for developing the concept of a lean enterprise.

The New Competitive Environment

Tuff Cut manufactures rotary mowers used for industrial and agricultural purposes. The firm has enjoyed consistent growth and loyal customers for 40 years because of its highquality product.

4

The New Competitive Environment

In recent years, some of

Tuff Cut’s market share has been eroded by competing products manufactured in the United States and abroad. Thus, managers at

Tuff Cut are looking for ways to become more competitive in terms of price, quality, and delivery.

Strategic Changes in the Way to

Manage an Organization

 Strategic decisions include decisions about the types of products a company should manufacture and how these products should be distributed.

Total Quality Management

Total quality management

(TQM) is a management system that seeks continual improvement by asking everyone in an organization to understand, meet, and exceed the needs of customers.

Once you have completed this chapter, you should be able to:

Objective 3

Describe the just-in-time (JIT) manufacturing philosophy and evaluate its strengths and weaknesses from financial and operating perspectives.

17

Principles of Just-in-Time

Manufacturing (JIT)

Just-in-time manufacturing is a production system that pulls products through the manufacturing process on the basis of market demand.

18

Principles of Just-in-Time

Manufacturing (JIT)

Inventory is pulled through the system based on market demand.

Small inventories of raw materials and finished goods are maintained.

The use of high-quality raw materials is critical to success.

Setup time of machines is minimized to allow for production in small batches.

Workcenter Processing Times with the Tuf Cut Plant

Fabrication:

20 units per hour;

3 minutes per unit

Welding:

10 units per hour;

6 minutes per unit

Painting:

30 units per hour;

2 minutes per unit

Assembly:

2.4 minutes per unit

Nonfinancial Performance

Measures

Cycle time is the total time required to move a unit from raw materials inventory to finished goods inventory.

32

Nonfinancial Performance

Measures

Processing time is the number of minutes in which value is added to raw materials.

33

Nonfinancial Performance

Measures

Wait time is the time a unit spends waiting to be processed.

34

Nonfinancial Performance

Measures

Wait time makes up the major portion of the cycle time required to move a unit of product through the plant.

35

Nonfinancial Performance

Measures

Production rate is the number of units a manufacturing system is capable of producing in a given time period.

36

Nonfinancial Performance

Measures

Processes that work at slow production rates and restrict the flow of goods or services are termed bottlenecks.

37

Nonfinancial Performance

Measures

Throughput represents the number of units completed by a process.

480

8 hours per shift x 60 minutes per hour = available minutes per shift

38

Nonfinancial Performance

Measures

Throughput represents the number of units completed by a process.

Production = One unit every six minutes

39

Nonfinancial Performance

Measures

Throughput represents the number of units completed by a process.

Throughput = 480 x 1/6 = 80 units per eight-hour shift

Once you have completed this chapter, you should be able to:

Objective 4

Explain how a traditional “processoriented” plant layout differs from a

“product-oriented” plant layout, and describe the financial consequences of each layout.

41

Exhibit 5

Traditional “Process-Oriented” Plant Layout

42

Product-Oriented Plant Layout

Process-oriented plant layouts typically are arranged according to machine function, with machines that perform similar functions placed together.

43

Product-Oriented Plant Layout

Process-oriented plant layout is based on manufacturing cells that meet the production requirements of products or product families.

44

Exhibit 6

“Product-

Oriented” Plant

Layout

45

Product-Oriented Plant Layout

A manufacturing cell is a group of related machines, typically arranged in the shape of a U.

46

Financial Benefits From JIT

 Reduced inventory levels result in lower carrying costs.

 Fast setup times contribute to short manufacturing cycle times.

 Responsive factories often gain a competitive advantage that translates into increased sales.

51

Drawbacks to the JIT

Manufacturing Philosophy

 Reducing inventory to a JIT level could cause closure in case of a strike by a supplier or a part of the company’s assembly plant.

 The cost savings from reducing inventories might be offset by increased delivery costs.

 JIT typically increases the number of batches and machine setups.

52

Once you have completed this chapter, you should be able to:

Objective 5

Identify the primary components of the theory of constraints.

53

The Theory of Constraints

54

Bottlenecks result from the processing speed of a machine or production area being less than that of other machines or production areas.

The Theory of Constraints

The theory of constraints states that by identifying a constraint, such as a bottleneck, that exists in the processing of a good or service and taking corrective steps, the process will be improved.

55

The Theory of Constraints

Recommended steps for process improvement:

Step 1: Attack a bottleneck by identifying the system’s constraints.

Step 2: Decide how to make the best use of the constraint.

Step 3: Subordinate all other decisions to those made in step 2.

Step 4: Improve the performance of the constraint.

Step 5: If a constraint has been broken, but a different bottleneck has been created, go back to step

1 and start over.
