367. Poka-yoke uses a number of devices to mistake proof a process.
Which of the following would NOT be included?
A
Fixture templates
B
Electric relays
C
Buzzer or light signals
D
Self-check inspections
The key question word is devices.
Inspections, for the most part, have human components and can be suspect.
However, most experts in the area of poka-yoke do recommend source, self and successive check methods.
Answer D is the correct, incorrect, choice.
Reference:
CSSBB Primer, Section X - 42 (and logic).
368. Consider the following definition: ""The best combination of machines and people working together to produce a product or service at a particular point in time.""
What lean concept is being described?
A
Standard work
B
A future state map
C
The value stream
D
Ultimate cycle time
The quote comes from Sharma (2001) and describes standard work.
The other answers were fabricated to sound good.
Answer A is correct.

369. Standard work sheets are required for standard operations.
What elements are included on the sheets?
I.
Cycle time based on takt time
II.
Work sequence - the order of operations
III.
Standard inventory on hand
IV.
The annual or semi-annual review date
A
I, II and III only
B
I, II and IV only
C
I, III and IV only
D
II, III and IV only
The answer choices would certainly indicate that one of the items is incorrect.
Shingo wrote that the operating sheets should be improved continuously.
Sharma allowed for monthly reviews.
Obviously, item IV is incorrect.
Answer A is correct.

CSSBB Primer, Section X - 44.
370. Identify the lean enterprise technique in which the videotaping of a segment of the operation is helpful:
A
SMED
B
TPM
C
Takt
D
FIFO
The distractor choices of inventory rotation (FIFO - first in, first out) and Takt time are fairly weak options.
Total productive maintenance (TPM) could have some video tape applications.
However, the best option is single minute exchange of dies (SMED).
The timing of rapid die change out can really benefit from video taping the process.
The tape can be run in slow motion to observe hinderances and delay areas, etc.
Answer A is correct.
Reference:
CSSBB Primer, Section X - 47 (and logic).
371. In the SMED system what is the real meaning of the single minute concept?
A
That dies will be exchanged in 1 minute or less
B
That dies will be exchanged in less than 5 minutes
C
That dies will be exchanged in less than 10 minutes
D
That dies will be exchanged in less than 15 minutes
Authorities differ slightly on the definition.
They all agree that it doesn't mean one minute or less (although desirable).
Some say it refers to a single digit of time (in minutes).
In this case, 9 minutes qualifies.
Others say under 10 minutes.
Answer C is considered correct.
