Knowledge that Transforms

Testing and cross‐validation of theories and paradigms are necessary to advance the field of manufacturing strategy. When the findings of one study are also obtained in other studies, using entirely different databases, we become more confident in the results. Replication alleviates concerns about spurious results and is one motivation for this study. We examine aspects of the tradeoffs concept, production competence paradigm, and a manufacturing strategy taxonomy framework. In regard to the tradeoffs concept, we found evidence of tradeoffs between some, but certainly not all, manufacturing capabilities of quality, cost, delivery, and customization. The relationships get sharper when controlling for process choice. For example, the tradeoff between cost and customization is particularly strong between plants that have different process choices. We find that such tradeoffs can change, or even disappear, however, once the process choice is in place. With respect to the production competence paradigm, our analysis shows a statistically significant correlation between production competence and operations performance in batch shops, but not in plants with other process choices. Finally, using variables similar to those of Miller and Roth, our data produced three similar clusters even though their unit of analysis was much more macro than ours. Controlling for process choice is consistent with the current manufacturing strategy literature that emphasizes dynamic development of capabilities within the context of path dependencies. A major argument of this strand of research is that operations decisions not only affect current capabilities, but also set the framework for development of capabilities in the future. That being the case, controlling for process choice (or other factors such as industry or markets) should contribute to the understanding of capability‐development paths adopted by different manufacturing plants. In short, we found at least partial support for each of the theories examined here, even though the theories seem on the surface to be contradictory and mutually exclusive. Controlling for process choice or other measures of dependency goes a long way in uncovering consistency across different theories and empirical studies in operations management.

The paper combines perspectives from international business and manufacturing to examine multinational plant location decisions. The location choice in manufacturing is between integrated and independent plants, while the international choice is between a foreign and domestic plant relative to their headquarters' country. The study empirically investigates whether these choices have different plant location determinants using data from a survey of plant managers of large, multinational firms. We find more evidence that the manufacturing choices benefit from consideration of international business issues than vice versa. However, managers rank determinants associated with manufacturing strategy considerably higher than those associated with intemational business.

This study uses survey data on several hundred automotive suppliers in North America to evaluate the determinants of inventory levels in high‐volume discrete parts manufacturing. We assess the magnitude of raw materials, work‐in‐process, and finished goods inventories held at automotive supply plants. Inventories are shown to be jointly determined by technological and managerial factors in a manner roughly consistent with classical inventory theory. Several categories of managerial practices are found to be important. Low inventories are linked to employee problem solving and frequent communication with customers. More unexpectedly, we find the absence of inventory differences between U.S.‐owned and Japanese‐owned plants in North America. This contrasts with substantial differences in inventory holding between US plants and those in Japan.

This paper, addressed to professors of operations management (om) in research institutions, suggests that the long‐term academic viability of our discipline requires the generation of a theory uniquely associated with the practice of OM. Such a theory will rest on foundations laid by other disciplines, but must find its own unique synthesis that attends to the problems of OM practice. The paper proposes a framework that recognizes physics, social psychology and philosophy as foundational disciplines for an integrative theoryof OM and suggests which concepts from those disciplines may find voice in such a theory.

It has been more than a decade since the quality movement was reborn in U.S. industry, and there is widespread dissatisfaction with the results of some of these programs. At the same time, product and service R&D is on the rise. These trends are incorporated here into an extension of the Utterback‐Abernathy model to examine the quality, technology, and performance relationship. Six hundred durable goods firms in 20 countries were surveyed and it was found that technology significantly moderated the association of R&D intensity and total quality management (tqm) with market share, controlling for industry category. In high technology firms, R&D intensity was significantly associated with market share; in low technology firms, tqm was significantly associated with market share. R&D intensity and tqm were significantly and inversely related, while R&D intensity and computer‐aided manufacturing (cam) were significantly and directly related.

Campbell Soup's continuous replenishment (CR) program is a novel innovation designed to improve the efficiency of inventory management throughout the supply chain. With CR (1) retailers pay a constant wholesale price but continue to participate in consumer promotions, (2) retailers transmit to the supplier daily inventory information via electronic data interchange (EDI), and (3) the supplier assumes responsibility for managing retailer inventories, i.e., vendor managed inventories (VMI). We develop simple inventory management rules to operate CR, and we test these rules with a simulation using actual demand data provided by Campbell Soup. On this sample we find that retailer inventories were reduced on average by 66% while maintaining or increasing average fill rates. This improvementreduces a retailer's cost of goods sold by ~1.2%, which is significant in the low profitmargin grocery industry. Furthermore, these savings could have been achieved without VMI.
