What are Andon systems or Andon lamps?
Andon lamps are an extremely simple system of visual factory management for helping teams identify when there is a problem with a process or machine. Originally they were developed as part of the Jidoka quality-control method within the Toyota Production System and have now been incorporated into standard lean manufacturing practice
Originally andon lamps were used to notify teams of a quality problem, and more frequently we see them installed on continuous flow lines to help inform operators of why machines have stopped. For example if i have an operator running two packaging machines and one of the machines stop, a simple Andon light stack can instantly tell the operator if he has a problem (and has to intervene) or if the machine has just run out of product.
Here is a sample Andon System, and there are more courtesy of google images:

Taking Andon systems to the next level…XL800 for the ultimate visual factory
The XL800 OEE system brings Andon systems into the 21st century by taking all the strengths of existing systems, adding even more functionality, whilst keeping the core simplicity.
When you install an XL800 OEE System on your machine or line the highly visual alphanumeric display system can be used to highlight KPI’s and running conditions just like any display system.
Basic functionality:
Almost instantly the XL800 OEE system can support your lean manufacturing implementation by very quickly enabling you to show:
More advanced functionality:
If you can get a signal from your machine to indicate why that machine has stopped then your XL800 could automatically display additional faults or alarms such as:
So what are the benefits of an XL800 as your Andon system?
