DMAIC and Automation

Autonomation is basically that if there is any problem in the machine that is causing defects, the the entire production line comes to a hault till the problem is fixed. It is used in Toyota Production System and Lean Manufacturing.  It may be described as "intelligent automation" or "automation with a human touch." There is supervision required in this process. At Toyota this usually means that if an abnormal situation arises the machine stops and the worker will stop the production line. Autonomation prevents the production of defective products, eliminates overproduction and focuses attention on understanding the problem and ensuring that it never recurs. It is a quality control process that applies the following four principles:

  1. Detect the abnormality.
  2. Stop.
  3. Fix or correct the immediate condition.
  4. Investigate the root cause and install a countermeasure.

This is very similar to the DMAIC process according to me. This process involes define, measure, analyise, improve and control.


DMAIC can be applied to Autonomation process when there is a problem!!! this is how lean can be mixed with six sigma can be applied together
