Genba (現場 genba) (also romanized as Gemba) is a Japanese term meaning "the real place." Japanese detectives call the crime scene genba, and Japanese TV reporters may refer to themselves as reporting from genba. In business, genba refers to the place where value is created; in manufacturing the genba is the factory floor. It can be any "site" such as a construction site, sales floor or where the service provider interacts directly with the customer.[1]
In lean manufacturing, the idea of genba is that the problems are visible, and the best improvement ideas will come from going to the genba. The genba walk, much like Management By Walking Around (MBWA), is an activity that takes management to the front lines to look for waste and opportunities to practice genba kaizen, or practical shopfloor improvement.
In quality management, genba means the manufacturing floor and the idea is that if a problem occurs, the engineers must go there to understand the full impact of the problem, gathering data from all sources. Unlike focus groups and surveys, genba visits are not scripted or bound by what one wants to ask.
Glenn Mazur introduced this term into Quality Function Deployment (QFD, a quality system for new products where manufacturing has not begun) to mean the customer's place of business or lifestyle. The idea is that to be customer-driven, one must go to the customer's genba to understand his problems and opportunities, using all one's senses to gather and process data.
