Andon
is a one of lean tool which provides a real time feedback of a system or
machine or status of process to an operator or concern person off a respective operations.
Mostly Andon uses a combination of lights and sounds to communicate status
updates, issues, and challenges.
Generally
Andon finds most of applications in the Assembly line, It helps to communicate
the problem as they arise and allows employees to alter the production process,
as necessary. By empowering employees on the front lines, Andon keeps workers
engaged with their tasks—all while working as an effective quality control
system.
This fits nicely with the Lean principle of “Respect for People.” If an
operator doesn’t feel trusted enough in the environment to stop the line based
on their own judgment, huge problems could occur later by not resolving the issue?
Another aspects in an Andon system is to create a right team with right
member to resolve the problems which may arise during daily operations. Given
that this can occur at any moment, knowing the players ahead of time will
increase the speed of resolution. If operators are left waiting around after pulling
the Andon cord, they will be less likely to pull it in the future because the
cost will seemingly outweigh the benefit.

Example of Andon
An perfect
example of andon system is tower lamp system in CNC machine, it shown in
the below image 
In which tower lamp separately highlighted and shown in the right side of the image and the following are the set of rules for each colors
The above picture shows the Andon rule for each color need to follow by operator who runs the machine .Respective color indicate the respective action need to be done. This Andon system need to train for a operator who takes the machine an appropriate training need to be given for betterment off Andon system
