Question 150: Which concept describes aligning production output exactly to customer demandβno more, no less?
- Push scheduling
- Pull system / Just-In-Time (Correct answer)
- Economic order quantity
- Batch-and-queue
Correct answer: Pull system / Just-In-Time
A pull / Just-In-Time system produces only what is needed, when it is needed, matching output precisely to customer demand.
Question 151: In supply chain management, 'lead time' refers to:
- Time to complete a quality inspection
- Time a manager spends supervising workers
- Time between placing an order and receiving it (Correct answer)
- Time to prepare a production schedule
Correct answer: Time between placing an order and receiving it
Lead time is the elapsed time from when an order is placed until the ordered items are received and available for use.
Question 152: How often must OSHA 300 Log summaries (Form 300A) be posted in the workplace?
- Continuously throughout the year in real time
- From February 1 through April 30 each year covering the prior calendar year (Correct answer)
- Only when OSHA requests an inspection
- Every six months during mandatory safety meetings
Correct answer: From February 1 through April 30 each year covering the prior calendar year
Employers must post the OSHA 300A summary form from February 1 through April 30 each year, summarizing the prior year's recordable injuries and illnesses.
Question 153: A production technician is measuring a bore diameter with a bore gage. The bore gage must first be set using a ring gage master. This process of setting the gage to a known value is called:
- Verification
- Attribute inspection
- Zeroing or mastering the gage (Correct answer)
- Gage R&R
Correct answer: Zeroing or mastering the gage
Mastering (zeroing) a gage means setting it to a known reference value so subsequent readings are relative to that standard.
Question 154: In lean manufacturing, which of the seven wastes (muda) refers to producing more than what the customer currently needs?
- Defects
