Q6. Value stream mapping in pharma is primarily used to:

• Identify and eliminate non-value-added steps to improve material and information flow
• Document only the regulatory-required steps in batch records
• Replace quality assurance activities with visual maps
• Design new drug molecules

Correct Answer: Identify and eliminate non-value-added steps to improve material and information flow

Q7. Kaizen events are best described as:

• Large capital investments to replace old equipment

• Define
• Measure
• Analyze
• Control

Correct Answer: Measure

Q9. Which process capability index accounts both for spread and how centered a process is within specification limits?

• Cp
• Cpk
• Pp
• Z-score

Correct Answer: Cpk

Q10. Which tool is most appropriate for monitoring process stability and detecting special-cause variation?

• Control charts (statistical process control)
• Value stream mapping
• Benchmarking
• Fishbone diagram

Correct Answer: Control charts (statistical process control)

Q11. When multiple potential root causes exist for a contamination event, which technique helps structure causes by categories?

• 5 Whys only
• Fishbone (Ishikawa) diagram
• Pareto chart that lists symptoms
• Scatter plot of unrelated variables

Correct Answer: Fishbone (Ishikawa) diagram

Q12. Total Productive Maintenance (TPM) in a pharma plant emphasizes:

• Exclusive reliance on external contractors for maintenance
• Maximizing equipment effectiveness through autonomous maintenance and operator involvement
• Postponing maintenance until equipment fails
• Reducing maintenance documentation to speed production

Correct Answer: Maximizing equipment effectiveness through autonomous maintenance and operator involvement

Q13. Benchmarking in operational excellence means:

• Copying competitor processes without analysis
• Comparing performance metrics and processes to industry best practices to identify improvement gaps
• Only comparing internal departments within the same plant
• Setting arbitrary targets without data

Correct Answer: Comparing performance metrics and processes to industry best practices to identify improvement gaps

Q14. Which KPI directly reflects the combined effects of downtime, reduced speed and scrap on manufacturing productivity?

• Batch Yield
• Overall Equipment Effectiveness (OEE)
• Inventory Turnover
• Cycle Time Alone

Correct Answer: Overall Equipment Effectiveness (OEE)

Q15. The Theory of Constraints recommends improving system throughput by focusing on:

• Eliminating all non-critical tasks first
• Identifying and managing the bottleneck (constraint) in the production flow
• Reducing the number of employees at the end of the line
• Maximizing utilization of non-bottleneck resources

Correct Answer: Identifying and managing the bottleneck (constraint) in the production flow

Q16. In a pharmaceutical quality system, the primary objective of CAPA (Corrective and Preventive Action) is to:

• Document deviations without further action
• Address root causes of nonconformances and prevent recurrence
• Increase batch release speed by skipping investigations
• Reduce the number of audits performed annually

Correct Answer: Address root causes of nonconformances and prevent recurrence

Q17. Which operational excellence practice most directly supports regulatory expectations for consistent product quality?

• Implementing statistical process control and process capability studies
• Focusing only on final product inspection
• Extending production hours without process review
• Reducing documentation to accelerate processes

Correct Answer: Implementing statistical process control and process capability studies

Q18. How does Kaizen differ from breakthrough improvement initiatives in pharma operations?

• Kaizen is focused on incremental, continuous improvements while breakthroughs are large, radical changes
• Kaizen requires large capital expenditure while breakthroughs require none
• Kaizen is only for administrative functions; breakthroughs are for production
• Kaizen eliminates the need for management oversight entirely

Correct Answer: Kaizen is focused on incremental, continuous improvements while breakthroughs are large, radical changes

Q19. Which of the following is considered a Lean waste (muda) in pharmaceutical manufacturing?
