Strengthening the empirical base of operations management

I suggest that the prospering fields of physics, medicine, and finance illustrate the value of a strong empirical dimension to research that is well integrated with theoretical research. I use empirical research in these fields to formulate a framework for classifying empirical research and illustrate that framework with a few selected examples in operations management. I offer some advice on data sources and approaches to conducting empirical research and suggest ways strengthening empirical research in operations management. This is obviously a partial treatment of a large subject and represents my personal point of view. This paper should encourage comments by others to further develop the topic and to offer alternative points of view.
