BEC Operations Management and Process Improvement 1 — Questions and Answers
Question 1: Just-In-Time (JIT) inventory management aims to:
- Receive goods only as they are needed in the production process to minimize inventory costs (Correct answer)
- Maintain large safety stocks to prevent production stoppages
- Order inventory in the largest possible batch to minimize ordering costs
- Outsource all inventory management to third-party logistics providers
Correct answer: Receive goods only as they are needed in the production process to minimize inventory costs
JIT minimizes inventory holding costs by scheduling material deliveries to arrive precisely when needed in the production process, reducing waste and storage requirements.
Question 2: The Economic Order Quantity (EOQ) model determines the order size that:
- Minimizes total inventory costs including ordering and holding costs (Correct answer)
- Maximizes gross profit margin on inventory sales
- Eliminates all stockout occurrences
- Reduces the number of suppliers needed
Correct answer: Minimizes total inventory costs including ordering and holding costs
EOQ calculates the optimal order quantity that minimizes total inventory costs by balancing the cost of placing orders against the cost of holding inventory.
Question 3: A bottleneck in operations management refers to:
- The step in a process with the least capacity that limits overall throughput (Correct answer)
- Excess inventory accumulating at a workstation
- A delay caused by supplier late deliveries
- Equipment that operates above its designed capacity
Correct answer: The step in a process with the least capacity that limits overall throughput
A bottleneck is the constraint in a production or service process where capacity is lowest, restricting the total output rate of the entire system.
Question 4: Total Quality Management (TQM) is characterized by:
- Organization-wide commitment to continuous quality improvement and customer satisfaction (Correct answer)
- Quality inspection performed only at the end of the production process
- A one-time quality improvement initiative led by senior management
- Setting a fixed acceptable defect rate as the quality standard
Correct answer: Organization-wide commitment to continuous quality improvement and customer satisfaction
TQM is a management philosophy emphasizing continuous improvement in all aspects of the organization, with every employee involved in enhancing quality and meeting customer needs.
Question 5: Six Sigma's primary goal is to reduce:
- Process variation and defects to near-zero levels (3.4 defects per million opportunities) (Correct answer)
- Employee headcount through automation
- Material costs by 6% per year
- The number of product variants in a product line
Correct answer: Process variation and defects to near-zero levels (3.4 defects per million opportunities)
Six Sigma is a data-driven quality methodology targeting near-perfect quality by reducing process variation to achieve no more than 3.4 defects per million opportunities.
Question 6: A Gantt chart is primarily used in project management to:
- Display project tasks, durations, and timelines visually across a calendar (Correct answer)
- Calculate the critical path and identify project dependencies
- Allocate budget across project phases
- Track employee hours worked on project activities
Correct answer: Display project tasks, durations, and timelines visually across a calendar
A Gantt chart is a bar chart tool that illustrates a project schedule, showing each task as a horizontal bar spanning its planned start and end dates.
