MR Operations and Process Management 2 — Questions and Answers
Question 1: What is the primary purpose of a SIPOC diagram in process management?
- To track financial performance metrics
- To provide a high-level view of Suppliers, Inputs, Process, Outputs, and Customers (Correct answer)
- To document corrective action requests
- To map risk probability and impact
Correct answer: To provide a high-level view of Suppliers, Inputs, Process, Outputs, and Customers
SIPOC diagrams give a macro-level overview of a process by identifying the five key elements before detailed mapping begins.
Question 2: Which lean concept focuses on producing only what is needed, when it is needed, and in the amount needed?
- Kaizen
- Poka-yoke
- Just-in-Time (JIT) (Correct answer)
- 5S
Correct answer: Just-in-Time (JIT)
Just-in-Time is a pull-based production philosophy that minimizes inventory and waste by synchronizing production with demand.
Question 3: A management representative discovers that a process consistently produces output at the upper control limit. What action is most appropriate?
- Accept results since they are within control limits
- Investigate for a special cause trend before the process goes out of control (Correct answer)
- Increase the upper control limit to accommodate the outputs
- Shut down the process immediately
Correct answer: Investigate for a special cause trend before the process goes out of control
Consistent results near a control limit may signal an emerging special cause that warrants investigation even if no points are yet out of control.
Question 4: In process capability analysis, a Cpk value of 0.8 indicates:
- The process is highly capable and centered
- The process is capable but slightly off-center
- The process does not meet minimum capability requirements (Correct answer)
- The process has no measurable variation
Correct answer: The process does not meet minimum capability requirements
A Cpk below 1.0 means the process does not consistently produce output within specification limits and needs improvement.
Question 5: Which of the following best describes a 'bottleneck' in process management?
- A quality checkpoint that slows inspection
- The step that limits overall throughput of the entire process (Correct answer)
- A regulatory approval stage
- The final step before product delivery
Correct answer: The step that limits overall throughput of the entire process
A bottleneck is the constraint that determines the maximum rate at which a process can deliver output.
Question 6: When conducting a Failure Mode and Effects Analysis (FMEA), the Risk Priority Number (RPN) is calculated as:
- Severity + Occurrence + Detection
- Severity × Occurrence × Detection (Correct answer)
- Severity × Occurrence / Detection
- Probability × Impact × Exposure
Correct answer: Severity × Occurrence × Detection
RPN = Severity × Occurrence × Detection, with each factor rated on a 1–10 scale to prioritize failure modes for corrective action.
Question 7: A value stream map is best used to:
- Define organizational reporting structures
- Visualize both value-added and non-value-added steps across a process flow (Correct answer)
- Document employee competency levels
- Track customer complaint resolution times
Correct answer: Visualize both value-added and non-value-added steps across a process flow
Value stream mapping reveals the complete flow of materials and information, highlighting waste and improvement opportunities.
