Andon lights are one of the visual management tools in places that have adapted a lean manufacturing philosophy, are used. If the concept of visual management is used, which is essential if we are walking on the floor of the production, and look, you can visually operate the status of the rows or cells. While these andon lights have a good purpose in the plant, they can also visit some falls.
If, on the production line, there is a problem, the person is an andon lightadvantage. They would then only have a switch on and the light came on. There are different colors to show, a tone, send a relay somewhere else where it is centrally located in lights, or any other number of methods. This is a sensible use of these visual management tool. The question now is what is being done?
To use this instrument effectively, we need action taken. The goal should be to prevent the light can be switched on again forthe same problem. But what usually happens is the first problem is fixed with a band aid approach, and is obliged to return.
So now provides management that the people running "when the light came, and begin to implement them all over the place. This is when they diluted the effect of light.
The right way to implement this strategy is the following:
You need to know the target. The goal is not only say that someone there is a problem. The goal is toto identify potential problems and prevent them from occurring.
Once the light goes on, people must know their responsibilities.
The first question needs to address ASAP will bring the line back up and running.
It must be traced the problem to its root cause. You can do this by using the 5 Why's (believe me, this works).
Once the cause is found, it must be corrected to where it is avoidable. This can result in disciplinary action, as most of these reasons are byOperators are not following procedures. This is where most of these systems fail. There is no accountability.
It should also be a log when the light came, and when the lights went out. Should also be documented, what was the cause, and what was the corrective action taken.
If these steps be taken, then with the andon light is a very good visual management tool. But if it is not completely to its logical end, then you only have plants of different colored lights on the ends of aPol, the look pretty cool. And, I've seen these places up close. They do exist. Do not be one of those places. Use the leader in as part of the overall visual management system, not as the whole system.
