Andon

Short Description

As part of the Toyota Production System, the Andon acts as a tool to implement simple symbolism on the shop floor to inform about a process or machine status. It helps you and your team to easily identify failures or discrepancies. The term Andon Cord is a lane at the assembly line to let operators give signals on line issues, the Andon Board is a screen or visual board showing all lamps and signals from a particular production area.

Why do you have to implement an Andon System?

Visualization

The Andon approach is a certain approach of visualizing equipment parameters and line status. The easier you visualize the necessary parameters the better your team can react accordingly. While machines can be programmed to give a signal, on assembly lines the team members and operators have to trigger the signal.

Quick Response

Equipment and line parameters become visualized right at the moment issues or malfunction occurs. Responsible engineers can react far faster and will be informed about the particular malfunction before they arrive at the machine or line.

Reduce Waste and Scrap

A major consequence of the quick response time to malfunctions is a reduction of waste and scrap. The better and faster your team is informed about any defects, the better and faster you can get rid of them and get the machine running.

How do you implement the Operator-Process Flexibility?

17_Andon_How


  • One of the most typical application of Andon is the Andon Cord
  • The Andon Cord helps operators to stop assembly lines once they are delayed because of several reasons or equipment does not work accordingly
  • The Andon Cord is stretched above the operators, close enough to be caught by operators but hanging high enough to not disturb them during their operations
