This study examines the publication output of individuals and business schools in the field of Production and Operations Management (POM). A ranking system was devised based upon publications in the leading POM journals. Two ranking approaches were applied to business schools: productivity and quality. Articles were counted in two ways: one ranking counted each article as one unit, and authors “shared” the unit equally, and the second ranking gave each contributor credit for one “distributed” unit. These are the first publication productivity rankings for the field of POM, and are based upon publications in the years 1989–1993.
