Q

Which of the following is not a step in Jidoka?

A

Don’t stop the production

17
Q

Autonomation is a lean methodology word for automation

A

False

18
Q

Can complex decisions be automated?

A

✓Yes, Nothing is too complex to be automated.
✓Decisions simply must be identified and broken down into MECE (mutually exclusive, comprehensively exhaustive) criteria in order to automate complex processes.

19
Q

Can a state of “true automation” ever be reached?

A

✓True automation can never be achieved as processes are constantly changing and there is always the possibility of errors/defects.
✓However, simple processes can be automated to the point where errors are so low that they are practically at a state of “true automation”.
