d) Anyone in the organization
View Answer
Explanation: Anyone in the organization can develop a poka-yoke device. All it needs is just a little empowerment of employees. This is the beauty of this method.
10. The use of electrical sensors to activate warning signals is an example of ______
a) Poka-yoke mechanism
b) Use of electronics
c) Use of electrical devices
d) Inform the police
View Answer
Explanation: Poka-yoke is also known as mistake-proofing. The use of electrical sensors to activate warning signals is an example of poka-yoke mechanism.
11. Poka-yoke is a strategy for implementing the policy of _______
a) Zero defects
b) Four defects
c) Seven defects
d) Eight defects
View Answer
Explanation: Poka-yoke is a strategy for implementing the policy of zero defects. Dr. Shigeo Shingo formalized the concept of Poka-yoke. It is considered as a quality improvement mechanism.
12. ________ and _______ are two major types of inspection for detecting errors.
a) Sampling inspection, 100% inspection
b) Sampling inspection, 99% inspection
c) Sampling inspection, 98% inspection
d) Sampling inspection, 97% inspection
View Answer
Explanation: Sampling inspection and 100% inspection are two major types of inspection for detecting errors. In sampling inspection, a few products are examined for defects. In 100% inspection, even a single defect is not tolerated.
13. Just-in-time is a strategy for implementing the policy of ________
a) Zero defects
b) Four defects
c) Seven defects
d) Eight defects
View Answer
Explanation: Just-in-time is a strategy for implementing the policy of zero effects. It is the principle of making what is needed, when it is needed in the amount needed.
