B2B Quality Control & Process Improvement 2 — Questions and Answers
Question 1: In B2B marketing, which Six Sigma metric measures the number of defects per million opportunities (DPMO)?
- Sigma level
- Process capability index (Cpk)
- DPMO (Correct answer)
- Yield rate
Correct answer: DPMO
DPMO (Defects Per Million Opportunities) is the standard Six Sigma metric for quantifying defect rates in a process.
Question 2: A B2B marketing team wants to reduce campaign approval cycle time. Which lean tool maps the current state of the workflow to identify waste?
- Fishbone diagram
- Value stream mapping (Correct answer)
- Control chart
- Pareto analysis
Correct answer: Value stream mapping
Value stream mapping visually documents each step of a process, making waste (delays, rework, redundant approvals) easy to spot and eliminate.
Question 3: Which quality principle states that 80% of problems typically stem from 20% of causes?
- Kaizen principle
- Pareto principle (Correct answer)
- Deming principle
- Juran principle
Correct answer: Pareto principle
The Pareto principle (80/20 rule) guides teams to prioritize the vital few causes that drive the majority of quality problems.
Question 4: In a B2B lead qualification process, a control chart shows a data point beyond the upper control limit. What does this indicate?
- Common cause variation within normal range
- Special cause variation requiring investigation (Correct answer)
- A process that is fully optimized
- Random noise that can be ignored
Correct answer: Special cause variation requiring investigation
A point beyond the control limits signals special cause variation — an unusual event that warrants investigation rather than routine adjustment.
Question 5: Which DMAIC phase focuses on identifying the root causes of a B2B marketing quality problem?
- Define
- Measure
- Analyze (Correct answer)
- Improve
Correct answer: Analyze
The Analyze phase uses tools like fishbone diagrams and regression analysis to identify root causes before solutions are designed.
Question 6: A B2B company implements mistake-proofing in its CRM data entry process to prevent duplicate records. This technique is known as:
- Kaizen
- Poka-yoke (Correct answer)
- Kanban
- Gemba walk
Correct answer: Poka-yoke
Poka-yoke refers to error-proofing mechanisms that prevent mistakes from occurring or make them immediately obvious when they do.
Question 7: When measuring B2B content marketing process quality, which metric best reflects process stability over time?
- Average conversion rate
- Standard deviation of cycle times (Correct answer)
- Total number of leads generated
- Cost per click
Correct answer: Standard deviation of cycle times
Standard deviation of cycle times reveals how consistently a process performs, with lower deviation indicating greater stability and predictability.
