LEGO SERIOUS PLAY is a facilitation method in which adults build models from LEGO bricks to think through and talk about real problems, from company strategy to team dynamics and personal goals. It grew out of a search in the mid-1990s for a better way to make strategy: LEGO owner Kjeld Kirk Kristiansen and business-school professors Johan Roos and Bart Victor began asking whether the bricks that had let children build their dreams for decades could help leaders build their vision of the future. Over the following years it was shaped into structured workshops and taken to market through a network of trained facilitators. Every session rests on one simple sequence, repeated again and again: a facilitator poses a challenge, every participant builds a model in response, and each person shares the story and meaning behind what they built. Because everyone builds before anyone speaks, quieter voices get an equal hearing, and the answers come from the people already in the room rather than from outside experts. On 1 June 2010 the LEGO Group stopped licensing the method and released it to the world under a Creative Commons licence, publishing an open-source guide to its principles, phases, etiquette and skills-building exercises, while continuing to make dedicated brick kits for practitioners. A global community of facilitators has used, taught and extended it ever since.
