An Andon System is a visual or digital alert system used in manufacturing and operational environments to signal when a problem occurs in a process. The term comes from Lean manufacturing and is commonly associated with production environments where workers need a quick way to raise issues that may affect quality, safety, or productivity.
Traditionally, Andon systems use visual signals such as lights, boards, or displays to indicate the status of a production line or operational process. For example, a green light may indicate that operations are running normally, while a yellow or red signal may indicate a problem that requires attention.
When an issue occurs, workers can activate the Andon system to alert supervisors or support teams. This allows problems to be addressed quickly before they escalate or disrupt production. In Lean environments, they help promote transparency and encourage teams to resolve issues as soon as they appear.
Digital systems extend the concept of Andon by integrating alerts with operational data and operational workflow platforms. Digital alerts can automatically notify teams when tasks fail validation checks, inspections detect issues, or processes deviate from defined procedures.
How This Applies to WorkfloPlus
WorkfloPlus supports operational visibility by capturing execution data and highlighting issues during tasks. If steps fail validation or require intervention, teams can respond quickly, helping organisations identify and resolve operational problems earlier.
Related Concepts
Andon systems are connected to several operational practices:
- Operational Visibility – understanding what is happening across operational processes.
- Operational Data Capture – recording information during tasks.
- Continuous Improvement – identifying and resolving operational issues.
- Connected Worker – workers supported by digital operational tools.
Why Andon Systems Matter
Quickly identifying operational problems helps organisations maintain productivity and prevent small issues from becoming major disruptions. Visual or digital alert systems ensure that teams can respond quickly when problems occur.
Digital tools that capture operational data make it easier to detect issues early and improve operational responsiveness.
