U.S. companies have implemented just-in-time purchasing (JITP) and total quality management (TQM) techniques to improve their global competitive position. The lack of empirical research on these techniques with firm's performance is the reason to explain further their strategic values as management innovations in different types and sizes of organizations. From a theoretical foundation on the relations between innovation, strategy and performance, the following research questions were generated: (1) Are JITP and TQM positively related to the firm's performance?, (2) Do the combination/sequence of implementing JITP and TQM have a relation with the firm's performance?, and (3) Is the relationship between JITP and TQM to the firm's performance moderated by any of industry type, firm size,firm type and/or duration of JITP and TQM techniques? A model is developed and hypotheses are proposed. A survey is mailed to firms operating in the U.S. that have implemented one or both techniques. Questionnaire items measuring JITP, TQM, performance, and moderating variables - industry type, firm size,firm type, and duration of JIT purchasing and TQM techniques— are either developed or borrowed from other studies. From rosters of the American Society for Quality Control and the National Association of Purchasing Management, 1884 target respondents result in …

The objective of this study was to examine the relationship between intensity of short-range and medium-range capacity management and effectiveness of manufacturing operations. Data were collected to test the null hypothesis which stated that intensity of short-range and medium-range capacity management does not influence manufacturing effectiveness. Intensity of short-range and medium-range capacity management was indicated by the following variables: (1) production standards; (2) priority determination; (3) delivery dates determination; (4) material requirements planning; (5) routing information; (6) capacity utilization; and (7) backlog measurement. Manufacturing effectiveness was indicated by the following variables: (1) delivery dates performance; (2) lead times; (3) subcontract work; (4) direct labor overtime; (5) direct labor efficiency; (6) plant and equipment utilization; and (7) work in process inventory. The population selected to provide data for this study is the manufacturing firms in the State of Texas with five hundred or more employees. Over 42 percent of the eligible firms responded to a six-page questionnaire. Several multivariate techniques were utilized for data analysis: (1) factor analysis; (2) canonical correlation analysis; (3) bivariate correlation; (4) multiple linear regression; (5) cross-tabulation; and (6) analysis of variance. The results of this research did not adequately support the rejection of the null hypothesis. …

This study identifies the concepts of reliability, cost of downtime, cost of spare parts, and procurement lead time as the four key moderators of spare parts availability. These concepts are used to establish a model to manage spare parts inventories. Reliability was assessed in terms of developing failure predictions for major component categories. Cost of downtime was evaluated by identifying various methods for determining costs associated with downtime. Cost of spare parts was examined to find correlations with economic indicators. These correlations were used to predict future price movements. Yearly changes in lead time were identified and correlated with economic indexes to develop movement predictability.

The purpose of this study is three-fold. First, based on the synthesis of literature on quality concepts, critical factors that must be practiced to achieve effective quality management in an organization were identified. A framework to be used by organizations to evaluate their quality assurance practices were developed. Second, a field survey was conducted to identify the degree to which quality assurance is being practiced in Indian Manufacturing organizations and to locate the organizational areas where better management control can make the quality assurance system more effective. Finally, an attempt was made to develop models that could be used to forecast the level of quality achieved.

This paper reports a study of the behavioral changes perceived by managerial and non-managerial personnel in a firm transforming from traditional manufacturing methods to the procedures of Just-In-Time manufacturing (JIT).

Work measurement systems are widely used by American manufacturers in establishing labor standards as inputs for budgeting, estimating, planning, evaluating, and managing production. These systems are used by defense related and non-defense related contractors alike. However in 1987, their use was required in United States Air Force major procurement contracts through Military Standard 1567A.
