『An Everyone Culture』要約

In An Everyone Culture, Harvard adult-development scholar Robert Kegan and co-author Lisa Laskow Lahey argue that most organizations waste enormous human potential by treating employees’ growth as separate from their work. Their central claim, drawn from decades of developmental psychology, is that adults continue to develop through identifiable stages of meaning-making, yet few workplaces are designed to support that development deliberately. The book introduces the concept of the "Deliberately Developmental Organization," or DDO—a company that weaves personal growth into its daily operations rather than relegating it to occasional training. Kegan and Lahey build the book around three extended case studies. Decurion, a movie-theater and real-estate company, uses "jumpstarts" and structured peer feedback so employees surface and examine the assumptions behind their behavior. Bridgewater Associates, the hedge fund founded by Ray Dalio, is presented as a radically transparent culture where recorded meetings and blunt critique are meant to expose individual blind spots. The third case, Next Jump, an e-commerce company, ties advancement and even job security to demonstrable personal development, embedding coaching into everyday tasks. Alongside these cases, the authors describe practices common to DDOs: dedicated time for reflection, honest feedback as a norm, and routines that turn ordinary workplace problems into opportunities for growth. They also address the difficulties of sustaining such a culture, including the fear and resistance that arise when people are asked to reveal weaknesses. The book concludes with guidance for leaders who want to experiment with DDO principles in their own organizations, emphasizing that the approach requires long-term commitment rather than a quick program.
