Jidoka describes a brand of automation where a machine stops itself if there is an abnormal situation. This technique was invented by Sakichi Toyoda back in the 1896 so that his power loom invention would stop and and allow workers to intervene and fix the issues. The 4 steps in Jidoka are:

  1. Detect the abnormality
  2.  Stop the machine
  3. Fix what is wrong
  4. Find and solve the root cause

It is considered one of the pillars of the Toyota Production System.
