The document discusses Andon, a visual signaling system used in factories to indicate issues that need attention. It suggests Andon signals can be lights or sounds and should be placed where operators and support staff can see or hear them. Locations can include operator stations, automated equipment, and areas needing monitoring. The document stresses determining signal needs, establishing protocols, training employees, and monitoring usage to ensure Andon is used effectively and problems are solved rather than just reacted to. It notes Andon implementation can range in cost but the most important factor is developing a culture where problems are stopped and supported.

2. Signal for help
Can be many different things
Usually thought of as a light, but audible is
sometimes a big benefit

3. Protecting the value add
Visual factory (no problems hidden)
JIT

4. Anyplace that is practical
› At an operator station
› As Jidoka on automation
› In a place where monitoring is required

5. Determine where andon is needed
Establish what signals will be used and when
Put the switch near the operator
Put the signal in a place where the
supporting person can see/hear it
Write instructions
Train
Practice, monitor, retrain

6. It can be expensive:
OR
It can be as cheap as you want it to be:
OR
Anything in between:

7. A light is just a light
The culture will decide if Andon will work
› Do you stop the line when there’s a problem?
› Are there support systems in place?
› Do you value a visual factory?
› Are you solving problems or just reacting?
› Is there motivation to use it?
