Customer satisfaction survey
Checklist mapped against all ISO 9001:2015 clause requirements (Correct answer)
Statistical Process Control (SPC) chart
Bill of materials review

Correct answer: Checklist mapped against all ISO 9001:2015 clause requirements

A gap analysis uses a clause-by-clause checklist to compare current practices against ISO 9001 requirements, identifying what must be developed or improved.

Question 2: In a QMS deployment, a 'turtle diagram' is BEST used to:

Display the organizational hierarchy of quality roles
Visually describe a process by mapping inputs, outputs, resources, methods, and measures (Correct answer)
Track supplier delivery performance over time
Chart defect trends using statistical process control

Correct answer: Visually describe a process by mapping inputs, outputs, resources, methods, and measures

A turtle diagram structures process analysis around 'with what' (resources), 'with whom' (competence), 'how' (methods), inputs, outputs, and performance indicators.

Question 3: Under JIT principles, which condition best supports a successful single-supplier strategy?

The supplier is geographically distant but cost-competitive
The supplier has consistently high quality and delivery performance (Correct answer)
The supplier has multiple competing plants
The part being sourced is a commodity with many alternatives

Correct answer: The supplier has consistently high quality and delivery performance

Single-supplier sourcing under JIT requires high confidence in the supplier's quality and delivery consistency to avoid production disruptions.

Question 4: An employer with 10 or fewer employees is generally exempt from OSHA recordkeeping unless:

They employ temporary workers
OSHA or BLS specifically notifies them to keep records (Correct answer)
They are in a high-hazard industry
They have a high injury rate

Correct answer: OSHA or BLS specifically notifies them to keep records

Employers with 10 or fewer employees are partially exempt from routine recordkeeping, but must comply if notified in writing by OSHA or the Bureau of Labor Statistics.

Question 5: When conducting a Job Hazard Analysis (JHA), the plant safety team should document:

Only incidents that have previously occurred for that task
Regulatory citations that may apply to the job
Each job step, associated hazards, and recommended controls (Correct answer)
Employee performance ratings alongside safety risks

Correct answer: Each job step, associated hazards, and recommended controls

A JHA systematically breaks a job into steps, identifies hazards for each step, and recommends controls to eliminate or reduce those hazards.

Question 6: What is the concept of 'takt time' and how does it relate to procurement planning?

The time between kanban card issuance and component delivery
The time required to complete one full production run
The rate at which products must be produced to match customer demand, driving material delivery frequency (Correct answer)
The average supplier lead time used in safety stock calculations

Correct answer: The rate at which products must be produced to match customer demand, driving material delivery frequency

Takt time (available time ÷ customer demand) sets the production rhythm, which directly determines how frequently materials must be delivered to sustain the line.

Question 7: A company has a gross requirement of 500 units, scheduled receipts of 100 units, and on-hand inventory of 75 units. What is the net requirement?

575 units
325 units (Correct answer)
500 units
425 units

Correct answer: 325 units

Net requirement = Gross requirement − Scheduled receipts − On-hand = 500 − 100 − 75 = 325 units.

Question 8: Takt time is calculated as:

Available production time divided by customer demand rate (Correct answer)
Customer demand rate divided by cycle time
Total production time divided by number of operators
Total units produced divided by total defects

Correct answer: Available production time divided by customer demand rate

Takt time = Available production time ÷ Customer demand, setting the pace at which products must be produced to meet demand.

Question 9: Which of the following is considered a 'privacy concern case' requiring special handling on the OSHA 300 log?

A laceration on the hand
A repetitive motion injury
A slip-and-fall in the parking lot

Question 10: On a plant P&L, depreciation of manufacturing equipment is classified as:

A below-the-line financing cost
A selling, general, and administrative (SG&A) expense
A product cost included in overhead and ultimately in COGS (Correct answer)
A period cost expensed directly to net income

Correct answer: A product cost included in overhead and ultimately in COGS

Manufacturing equipment depreciation is a product (inventoriable) cost that flows through overhead, into WIP, then finished goods, and finally COGS when product is sold.

Question 11: When implementing a pull system, what is the function of a kanban card?

Document machine maintenance schedules
Track employee attendance and hours worked
Authorize the production or movement of a specific quantity of material (Correct answer)
Record daily production output for management reporting

Correct answer: Authorize the production or movement of a specific quantity of material

A kanban card is a visual signal that authorizes upstream processes to produce or supply a defined quantity only when downstream consumption creates a need.

Question 12: A plant manager wants to implement cross-docking for inbound materials. What is the primary benefit?

Increased storage capacity in the warehouse
Elimination or minimization of warehousing by transferring goods directly from inbound to outbound (Correct answer)
Improved supplier payment terms through faster invoice processing
Reduced transportation costs through larger shipment consolidation

Correct answer: Elimination or minimization of warehousing by transferring goods directly from inbound to outbound

Cross-docking routes inbound shipments directly to outbound vehicles with minimal or no storage time, reducing handling, storage costs, and lead time.

Question 13: A plant's return on assets (ROA) declined despite higher revenue. The most likely explanation is:

Asset base grew faster than net income due to a capital expansion (Correct answer)
Depreciation expense decreased, inflating asset book value
Revenue recognition was accelerated into the current period
The plant improved its asset utilization rate

Correct answer: Asset base grew faster than net income due to a capital expansion

If assets increase proportionally more than net income—common during capital expansion—ROA (Net Income ÷ Total Assets) declines even as revenue grows.

Question 14: In MRP, what is the purpose of 'time-phasing' requirements?

To offset gross requirements by lead time so orders are placed at the right time (Correct answer)
To phase out obsolete materials from inventory
To stagger demand across shifts for labor balance
To synchronize production with customer shipping windows

Correct answer: To offset gross requirements by lead time so orders are placed at the right time

Time-phasing offsets gross requirements by the item's lead time so that planned order releases occur early enough to receive materials when needed.

Question 15: In electrical utility billing, a 'demand charge' is based on:

The highest 15- or 30-minute average power draw recorded in the period (Correct answer)
The number of electrical circuits installed in the facility
Total kilowatt-hours consumed during the billing period
Power factor measured at the end of the month

Correct answer: The highest 15- or 30-minute average power draw recorded in the period

Demand charges are based on peak power demand (highest average over a 15- or 30-minute interval), reflecting the utility's cost to maintain capacity for peak usage.

Question 16: A steward files a grievance claiming a supervisor violated the seniority provision when assigning overtime. At Step 1, the plant manager should:

Meet with the steward, investigate the facts, and issue a written response within the contractual timeframe (Correct answer)
