JIT & JIDOKA Flashcards
(32 cards)
A problem gets automatically detected, stops the machine (or process) and alerts the operator to take action.
Autonomation
making products or delivering services based on actual customer demand
Just-In-Time (JIT)
Pillars of Lean
JIT and Jidoka
Inventory is a form of waste (true or false)
True
Task-switching is a form of waste (true or false)
True
German word for beat or pulse
Tact Time
Leveling out the demand over a period of time when you know there will be fluctuations in demand at work.
Heijunka = “leveling”
Automation vs. Autonomation
Autonomation is automation with a human touch
“Paper Lantern”
Refers to any visual display that shows status information
Andon
a mechanism, usually a rope, that a worker may pull to signal the need for assistance, and which will stop the line if the problem is not fixed under Takt time.
Andon Cord
a position on the assembly line where a zone process is completed. It is at these positions that the line will stop should an abnormality not be corrected on time - at the end of takt time.
Fixed-Position Stop
-“mistake-proofing” or “error-proofing”
-Techniques using low-cost devices or innovations that make it impossible to make mistakes
-Helps people process work right the first time.
Poke-Yoke

JIT
Which methodology asks the following questions?
*Has the system been error proofed?
*Has a stop-gap been established?
*Has root cause been identified?
Jidoka
The concept of building quality into a process yet not having to inspect it is part of which methodology
Jidoka
Which of the following is not a step in Jidoka?
Don’t stop the production
Autonomation is a lean methodology word for automation
False
Can complex decisions be automated?
✓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.
Can a state of “true automation” ever be reached?
✓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”.
Business processes must be analyzed and built for
