A type of visual control that displays the current state of work (i.e., abnormal conditions, work instructions, job progress info). It is one of the main tools of Jidoka.
Line indicator light or board hung above the production line to act as a visual control. Andons are used to visually signal an abnormal situation.
a line stop; typically a cord that a worker can pull to stop the assembly line when he or she detects a defect; an example of jidoka.
A visual signal. Typically, a light mounted on a machine or line to indicate a potential problem or work stoppage.
Indicator above production line to signal production conditions. Often uses green/yellow/red colors to indicate status.
A tool of visual management, originating from the Japanese word for 'lamp'. Most commonly, andons are lights placed on machines or on production lines to indicate operation status. Andons are commonly color-coded green (normal operations), yellow (changeover or planned maintenance), and red (abnormal, machine down). Often combined with an audible signal such as music or alarms.
1) An electronic board that provides visibility of floor status and provides information to help coordinate the efforts to linked work centers. Signal lights are green (running), red (stop), and yellow (needs attention). 2) A visual signaling system.
The Andon is used as a system to alert of problems in process. It gives the person or automated machining the ability to stop production when a defect is found or ability to continue with STW (Standardized Work) has been interrupted. Common reasons for use of the Andon is part shortage, defect created or found, tool malfunction, or a safety problem has been created.
