This chapter distinguishes five stages in the lifecycle of management ideas: innovation, diffusion, institutionalization, dormancy, and rebirth. Research at each stage can help research at other stages. It also examines the lifecycle stages of both abstract and specific management ideas. Studying these simultaneously can help address some of the most resilient and enduring questions about each. Finally, the authors conceptualize the conjunction of forces which must co-occur to cause stage transitions. They do so to avoid drawing conclusions about why transitions happen when the same conclusions might be drawn when they do not.
