Every innovation or new product development team faces a fundamental tension: When does one transition from the ideation to the execution phase? Too early a transition risks missing a great yet unrealized idea, and too late a transition risks being unable to bring the product to market on time. This significant and ubiquitous tension poses a challenge for researchers because of the nuanced nature of imagination and creativity and the need to combine that with creating an actual item based on one’s designs. In “Ideation-Execution Transition in Product Development: An Experimental Analysis” (Management Science, 2018) by Michigan Ross Professors Stephen Leider and William Lovejoy, as well as their colleague Evgeny Kagan from the Johns Hopkins Carey Business School, the authors use a novel experimental design to reveal some expected outcomes (later transitions do not change mean performance but increase variance and risk significantly) and some unexpected ones (it is not so much the timing of the transition that drives mean performance, but rather who has decision rights). Specifically, designers should not make the transition decision; the timing should be an exogenously imposed constraint. This external requirement significantly changes designers’ behaviors and results.
