Just-in-Time Processing (JIT)Just-in-Time Processing (JIT)

JIT is a business philosophy that focuses on reducing time and cost and eliminating poor quality.

JIT organizes work cells that perform several manufacturing steps.

Workers are cross-trained to perform more than one task. This provides flexibility and worker pride and involvement in the final product.

Because products have limited movement between departments, the nonvalue-added cost of transporting products and parts is reduced.

Accounting for Just-in-Time OperatonsAccounting for Just-in-Time Operatons

Fewer Transactions. The accounting system is simpler because there are fewer transactions to record.

Combined Accounts. All in-process work is combined with raw materials to form a new account, Raw and In Process (RIP) Inventory.

Nonfinancial Performance Measures. There is a greater emphasis on nonfinancial measures.

Direct Tracing of Overhead. Indirect labor is directly assigned to product production cells.

In a just-in-time operating environment, the accounting system will have the following characteristics:

C11 - 25

Nonfinancial Performance MeasurementNonfinancial Performance Measurement

1. Measures of product quality

2. Customer complaints and warranty experience

3. Customer satisfaction and retention rates

4. Product availability and on-time performance

5. New product time to market and market share

Nonfinancial performance measures combined with conventional financial measures provide a balanced performance perspective.

C11 - 26

Prevention costs are the costs of activities that prevent defects from occurring during the design and delivery of products or services.

Appraisal costs are the costs of activities that detect, measure, evaluate, and audit products and processes to ensure that they conform to customer requirements and performance standards.

Costs of Controlling QualityCosts of Controlling Quality

C11 - 27

Internal failure costs are the costs associated with defects discovered by a business before the product or service is delivered to the consumer.

External failure costs are the costs incurred after defective units or services have been delivered to consumers. Although difficult to measure, it may be the largest cost in the quality equation.
