NPS Performance Improvement & Quality Metrics 1 — Questions and Answers
Question 1: What does the acronym PDCA stand for in the context of quality improvement cycles?
- Plan, Do, Check, Act (Correct answer)
- Perform, Develop, Control, Analyze
- Prioritize, Define, Create, Assess
- Process, Document, Correct, Adapt
Correct answer: Plan, Do, Check, Act
PDCA (Plan, Do, Check, Act) is a four-step iterative management method used for continuous improvement of processes and products.
Question 2: Which performance metric is calculated by dividing the number of defective units by the total number of units produced, then multiplying by 100?
- Process capability index
- Defect rate (Correct answer)
- Yield rate
- Throughput rate
Correct answer: Defect rate
The defect rate is calculated as (number of defective units / total units produced) × 100, expressing the percentage of outputs that fail to meet quality standards.
Question 3: A Key Performance Indicator (KPI) is best described as:
- A financial report generated monthly by management
- A measurable value that demonstrates how effectively an organization is achieving key objectives (Correct answer)
- A software tool used to track employee attendance
- A standardized training curriculum for new employees
Correct answer: A measurable value that demonstrates how effectively an organization is achieving key objectives
KPIs are quantifiable measures used to evaluate the success of an organization or a particular activity relative to its stated goals.
Question 4: Which quality improvement tool uses a diagram shaped like a fish skeleton to identify potential causes of a problem?
- Pareto chart
- Control chart
- Fishbone (Ishikawa) diagram (Correct answer)
- Scatter plot
Correct answer: Fishbone (Ishikawa) diagram
The fishbone (Ishikawa) diagram organizes potential causes of a problem into categories, visually resembling a fish skeleton, making it useful for root cause analysis.
Question 5: What is the primary purpose of a control chart in performance monitoring?
- To display the frequency distribution of data
- To rank problems in order of importance
- To monitor process variation over time and detect unusual patterns (Correct answer)
- To compare actual performance against targets
Correct answer: To monitor process variation over time and detect unusual patterns
Control charts are used to study how a process changes over time, distinguishing between common cause variation and special cause variation.
Question 6: Which quality management methodology is primarily focused on identifying and eliminating waste (muda) in processes?
- Six Sigma
- Lean (Correct answer)
- Total Quality Management (TQM)
- ISO 9001
Correct answer: Lean
Lean methodology focuses on creating more value for customers by eliminating waste — activities that consume resources without adding value.
Question 7: In performance improvement, 'baseline measurement' refers to:
- The minimum acceptable level of performance required by regulators
- The data collected at the start of an improvement initiative to serve as a reference point (Correct answer)
- The average performance across all departments in the organization
- The target performance level set by senior management
Correct answer: The data collected at the start of an improvement initiative to serve as a reference point
A baseline measurement captures the current state of performance before any improvement interventions, providing a reference point to measure the impact of changes.
