From day one, Toyota has prioritised high quality in its products and services. Over the years we have introduced principles and processes to ensure that our quality levels continue to improve.
The origin of the Andon Principle
The Andon Principle was created by Sakichi Toyoda in 1924 to enable his Type G-automatic loom machine to stop whenever an issue occurred. Originally it referred to a button or pull-chord, which automatically halted production when activated by a member of staff. The term comes from the Japanese word for a paper lantern, referring to an illuminated signal notifying another of a problem. Andon now refers to a visual aid that highlights a problem where action is required in a specific area or workstation. This allows a solution to be found before it is too late to rectify.
