Obeya

Obeya in Japanese means simply “big room.” At Toyota it has become a major project-management tool, used especially in product development, to enhance effective and timely communication. Similar in concept to traditional “war rooms,” an obeya will contain highly visual charts and graphs depicting program timing, milestones and progress to date, and countermeasures to existing timing or technical problems. Project leaders will have desks in the obeya as will others at appropriate points in the program timing. The purpose is to ensure project success and shorten the PDCA cycle.

Takeshi Uchiyamada is credited with creating the obeya management system. He had just been named Chief Engineer for arguably the most revolutionary product in Toyota’s history. Uchiyamada lacked the technical depth required to develop and commercialize the advanced hybrid technology that would be required. In fact, no single person at Toyota did. He quickly realized that he would need an unprecedented level of collaboration, transparency and speed of decision making to make this program a success.

Consequently his first pathbreaking innovation had nothing to do with engine technology. Recognizing that his job would be to effectively integrate the efforts of diverse experts and keep the project on track to achieve no compromise targets for performance cost and schedule, he created the “obeya management system.” In this system he met every two to three days with all required technical experts in a room in which all pertinent information was posted on the walls. This information was available to everyone on the team at any time. The G21, which the world has come to know as the Prius, went on to revolutionize the auto industry, dramatically raising the bar for fuel economy and leaving competitors years behind. And the obeya system, credited with making a major contribution to the Prius success, became a development staple at Toyota.
