Oobeya - Japanese for "great room" or "war room" - refers to a form of project management at Toyota and is part of the Toyota Production System,[1] and thus a component of Lean Management and Lean Production . During product and process development, all persons involved in the planning are in a 'great room' united to achieve fast communication and decision-shortest paths. This eliminates the traditional barriers that have become the "departmental thinking" developed over time. In a way one can even speak of an extension of the team spirit at the administrative level. At Toyota in vehicle developments are in significantly less than 20 months now possible (By comparison, the average for other car makers is 36 months).
