Teaching Operations Management from a Science of Manufacturing *

Recently, there has been much concern over the dumbing down of production and operations management (POM) courses in response to the repudiation of the theory-heavy operations research (OR) approach that became dominant during the 1970s. However, although almost everyone agrees that a new POM framework is needed, there is as yet little agreement on what it should be like. As a result, there is currently a huge variance among POM courses at different universities, ranging all the way from traditional OR courses to almost purely anecdotal case-oriented courses. Although academics have struggled with the search for an appropriate level of methodological rigor in POM courses, our customers (i.e., students and the firms that hire them) have been inundated by a blizzard of management buzzwords. Although many of these undoubtedly contain kernels of truth, the very nature of the buzzword approach is such that it provides little balanced guidance as to what methods work well in a given situation. In recognition of these disparities, POM researchers have begun trying to systematically describe the underlying behavior of production systems. The goal is to provide a framework that will help organize educational approaches and business practices in a consistent fashion. In this paper, we describe our attempt at the needed “science of manufacturing,” which we call factory physics, and illustrate how it fits into a new paradigm of POM teaching.
