BSIE Total Quality Management 5 — Questions and Answers
Question 1: What is the primary goal of supplier qualification and development programs within a TQM framework?
- To reduce the number of suppliers to a single approved vendor for each part
- To extend quality management practices upstream to ensure incoming materials meet requirements (Correct answer)
- To transfer liability for product defects from the manufacturer to the supplier
- To negotiate lower prices by leveraging competitive bidding among multiple suppliers
Correct answer: To extend quality management practices upstream to ensure incoming materials meet requirements
TQM extends quality responsibility to the supply chain by qualifying suppliers, building long-term partnerships, and helping them improve their processes to consistently deliver conforming materials.
Question 2: In a SIPOC diagram used in TQM and Six Sigma, what does the 'O' represent?
- Objectives of the quality improvement project
- Outputs produced by the process and delivered to customers (Correct answer)
- Operators responsible for each step of the process
- Opportunities for defects within the process
Correct answer: Outputs produced by the process and delivered to customers
In SIPOC (Suppliers, Inputs, Process, Outputs, Customers), 'O' stands for Outputs — the products, services, or information that the process produces and delivers to customers.
Question 3: Which of the following situations would cause a special cause of variation in a process?
- Normal tool wear that occurs gradually over thousands of parts
- Random variation inherent in the raw material composition
- A machine operator who has been trained to follow the standard procedure
- A sudden equipment malfunction that causes a spike in defect rate (Correct answer)
Correct answer: A sudden equipment malfunction that causes a spike in defect rate
Special cause variation results from identifiable, non-random events such as equipment malfunctions, operator errors, or material changes — unlike common cause variation that is inherent in the process.
Question 4: The Malcolm Baldrige National Quality Award evaluates organizations in which core performance category?
- Financial auditing and accounting accuracy
- Leadership, strategy, customers, measurement, workforce, operations, and results (Correct answer)
- ISO 9001 certification compliance and documentation
- Six Sigma project completion rates and Black Belt certifications
Correct answer: Leadership, strategy, customers, measurement, workforce, operations, and results
The Baldrige Award criteria assess seven categories: Leadership; Strategy; Customers; Measurement, Analysis, and Knowledge Management; Workforce; Operations; and Results.
Question 5: What distinguishes a c-chart from a u-chart in statistical process control?
- A c-chart monitors continuous variables while a u-chart monitors attribute data
- A c-chart tracks defects in samples of equal size while a u-chart tracks defects per unit for varying sample sizes (Correct answer)
- A c-chart uses three-sigma limits while a u-chart uses two-sigma limits
- A c-chart is used for service processes while a u-chart is used for manufacturing
Correct answer: A c-chart tracks defects in samples of equal size while a u-chart tracks defects per unit for varying sample sizes
The c-chart monitors the count of defects in samples of constant size, while the u-chart monitors the average number of defects per unit when sample sizes vary.
Question 6: In TQM, 'empowerment' of employees primarily means:
- Giving workers authority to stop production when they detect a quality problem (Correct answer)
- Allowing workers to set their own working hours and take unscheduled breaks
- Requiring workers to complete ISO documentation without management review
- Transferring managerial salary budgets directly to frontline employees
Correct answer: Giving workers authority to stop production when they detect a quality problem
Employee empowerment in TQM gives workers the authority and responsibility to take action — including stopping the line — when they identify quality problems, making quality everyone's responsibility.
Question 7: Which of the following best describes the concept of 'design for quality' (DFQ) in TQM?
- Inspecting finished products against design specifications before shipment
- Incorporating quality requirements and customer needs into the product design phase to prevent defects (Correct answer)
- Creating a quality manual that documents all manufacturing procedures
- Assigning quality inspectors to each stage of the production process
Correct answer: Incorporating quality requirements and customer needs into the product design phase to prevent defects
Design for quality integrates quality considerations into product design from the start, using tools like FMEA and QFD to prevent defects rather than detecting them after production.
