P13716: Andon System for Toyota Production
Systems Lab
Project Objective: The objective of this project was to introduce Jidoka
to the four-station assembly line within the Toyota Production Systems
Lab at the Rochester Institute of Technology.
Background Information: Jidoka is a term used in the Toyota Production
System that refers to diagnosing an abnormality immediately and
correcting it accordingly so that defects are not passed along to the
next operator. An Andon system is a principal components of Jidoka.
Mechanical Andon Systems:
