NPS Performance Improvement & Quality Metrics 2 — Questions and Answers
Question 1: Benchmarking in performance management is the process of:
- Setting internal performance targets based on historical data
- Comparing an organization's performance metrics against industry best practices or competitors (Correct answer)
- Testing new equipment before it is used in production
- Establishing financial budgets for the upcoming fiscal year
Correct answer: Comparing an organization's performance metrics against industry best practices or competitors
Benchmarking involves comparing an organization's processes and metrics against industry best practices or leading organizations to identify areas for improvement.
Question 2: A histogram is used in quality management to:
- Show the relationship between two variables
- Track process performance over time
- Display the frequency distribution of data values (Correct answer)
- Rank causes of problems by frequency
Correct answer: Display the frequency distribution of data values
A histogram displays the frequency distribution of data values, showing how often different ranges of values occur, helping identify patterns, skewness, and outliers.
Question 3: Six Sigma aims to reduce process defects to no more than:
- Fewer than 10 defects per million opportunities
- Zero defects in all processes
- Fewer than 3.4 defects per million opportunities (Correct answer)
- Fewer than 100 defects per thousand opportunities
Correct answer: Fewer than 3.4 defects per million opportunities
Six Sigma targets a process quality level of 3.4 defects per million opportunities (DPMO), representing a process that is 99.99966% defect-free.
Question 4: A process flowchart is primarily used to:
- Display financial performance over time
- Visually represent the sequence of steps in a process to identify inefficiencies (Correct answer)
- Calculate the cost of quality in a department
- Track individual employee performance metrics
Correct answer: Visually represent the sequence of steps in a process to identify inefficiencies
A process flowchart visually maps out each step in a process using standardized symbols, helping teams understand the current state, identify bottlenecks, and design improvements.
Question 5: 'Cycle time' in performance metrics refers to:
- The total cost associated with completing a product or service
- The total time required to complete one full cycle of a process from start to finish (Correct answer)
- The number of cycles a machine can complete in one hour
- The time employees spend on training activities
Correct answer: The total time required to complete one full cycle of a process from start to finish
Cycle time measures the total elapsed time from the start of a process to its completion for one unit, including processing time, wait time, and any delays.
Question 6: A Pareto chart is based on the principle that suggests:
- 50% of problems are caused by 50% of factors
- All causes of a problem contribute equally to its occurrence
- Approximately 80% of problems are caused by 20% of the causes (Correct answer)
- The most frequent problems are always the most critical
Correct answer: Approximately 80% of problems are caused by 20% of the causes
The Pareto principle (80/20 rule) states that approximately 80% of effects come from 20% of causes, helping teams prioritize improvement efforts on the most impactful factors.
Question 7: The DMAIC methodology in Six Sigma stands for:
- Define, Measure, Analyze, Improve, Control (Correct answer)
- Develop, Monitor, Assess, Implement, Check
- Design, Map, Audit, Inspect, Complete
- Define, Manage, Analyze, Integrate, Correct
Correct answer: Define, Measure, Analyze, Improve, Control
DMAIC (Define, Measure, Analyze, Improve, Control) is a data-driven improvement cycle used for optimizing and stabilizing business processes.
