Obeya or Oobeya refers to a form of project management and is a component of lean manufacturing. Even more specifically, the Toyota Production System. The obeya is a similar concept to a "bridge room" or a "war room."
During the product and process development, all individuals involved in managerial planning meet in Obeya to speed communication and decision-making. This is intended to reduce "departmental thinking" and improve other methods of communication which tend to introduce forms of waste into the process.
Conceptually akin to traditional “war rooms,” an Obeya will contain: visually engaging charts, graphs, milestones, progress, countermeasures and any other forms of critical information for attendees to make decisions accurately and efficiently.
