The production performance benefits from JIT implementation

Abstract The intense competition in the current marketplace has forced firms to reexamine their methods of doing business. The US manufacturers have struggled with growing trade deficits and outsourced operations, while strong market competitors have emerged, using superior manufacturing practices in the form of just-in-time (JIT) and continuous process improvement. Although proponents cite the many benefits of JIT adoption, its implementation rate in the US has been relatively conservative. This study uses survey responses from executives at 95 JIT-practicing firms to better understand the benefits that firms have experienced through JIT adoption, and whether a more comprehensive implementation is worthwhile. The research results demonstrate that implementing the quality, continuous improvement, and waste reduction practices embodied in the JIT philosophy can enhance firm competitiveness. JIT implementation improves performance through lower inventory levels, reduced quality costs, and greater customer responsiveness. This study indicates that JIT is a vital manufacturing strategy to build and sustain competitive advantage.

AN EXAMINATION OF THE RELATIONSHIPS BETWEEN JIT AND FINANCIAL PERFORMANCE

Abstract Despite abundant information explaining the expected benefits from successful just-in-time (JIT) implementation, only tenuous validation of the linkage between financial performance and JIT exists. Managers act rationally in implementing JIT if they are convinced that JIT enhances firm performance. From both a cross-sectional and longitudinal perspective, this survey study of 253 US manufacturing firms finds significant statistical relationships between measures of profitability and the degree of specific JIT practices used. The evidence provides empirical support to the premise that firms that implement and maintain JIT manufacturing systems will reap sustainable rewards as measured by improved financial performance.

The role of performance measures and incentive systems in relation to the degree of JIT implementation

Abstract The shift to world-class manufacturing strategies has necessitated complementary changes in management accounting systems (MAS). Using survey data obtained from top manufacturing executives at 253 US firms, this study empirically examines the relationship between the level of just-in-time (JIT) practices implemented by US manufacturing firms and the performance measures and incentive systems that are incorporated in their MAS. The statistical tests provide empirical evidence that the use of non-traditional performance measures such as bottom-up measures, product quality, and vendor quality, as well as incentive systems of employee empowerment and compensation rewards for quality production are related to the degree of JIT practices implemented.

AN EMPIRICAL EXAMINATION OF COST ACCOUNTING PRACTICES USED IN ADVANCED MANUFACTURING ENVIRONMENTS

Despite arguments that traditional product costing and variance analysis operate contrary to the strategic goals of advanced manufacturing practices such as just in time (JIT), total quality management (TQM), and Six Sigma, little empirical evidence exists that cost accounting practices (CAP) are changing in the era of continuous improvement and waste reduction. This research supplies some of the first evidence of what CAP are employed to support the information needs of a world-class manufacturing environment. Using survey data obtained from executives of 121 U.S. manufacturing firms, the study examines the relationship between the use of JIT, TQM, and Six Sigma with various forms of traditional and non-traditional CAP. Analysis of variance tests (ANOVA) indicate that most traditional CAP continue to be used in all manufacturing environments, but a significant portion of world-class manufacturers supplement their internal management accounting system with non-traditional management accounting techniques.
