In this article, we draw on the product life cycle framework to propose an adapted model for evaluating the evolution of a theory. The product life cycle was designed as an economic analysis tool, and its intuitive usefulness led to its adaptation for a variety of disciplines. Nevertheless, it has not been applied to theory. We propose a five-stage model of theory development: (1) emergence, (2) development, (3) maturity, and (4) decline toward (5) death or reemergence. The proposed model is then tested by applying it to work motivation theory. We conclude by offering implications and recommendations for using the theory life cycle model in research, teaching, and practice.
