Obeya
Obeya (from Japanese Ōbeya 大部屋 "large room") is a team spirit improvement tool at an administrative level, originating from a long history of learning & improving. It is considered a component of lean manufacturing. Obeya objectives are rapid decision-making, reduction in rework and reconsiderations, and reduction in unnecessary discussions. The Obeya Association enumerates 11 Obeya Principles that define Obeya and guide its improvement.
The earliest notion of concept is believed to be the Analects of Confucius nearly 2500 years ago (China, 206 BC–220 AD). The use of Obeya rooms has been proven by many companies to be successful.
