CPP Quality Assurance & Improvement 3 — Questions and Answers
Question 1: In the context of packaging QA, what is the primary purpose of a Gauge R&R study?
- To quantify measurement system variation due to operators and equipment (Correct answer)
- To calculate process capability indices
- To set specification limits for packaging dimensions
- To audit supplier measurement equipment
Correct answer: To quantify measurement system variation due to operators and equipment
Gauge R&R (Repeatability and Reproducibility) assesses how much of the total variation in measurement data comes from the measurement system versus the process.
Question 2: A packaging company implements FMEA before launching a new blister pack line. At what stage is FMEA most valuable?
- During product and process design, before production begins (Correct answer)
- After the first production run reveals defects
- When customer complaints exceed a threshold
- During the annual management review
Correct answer: During product and process design, before production begins
FMEA is a proactive tool most effective when applied in the design phase to identify and mitigate potential failure modes before they occur.
Question 3: Which lean quality concept focuses on stopping production when a defect is detected to prevent further defective output?
- Jidoka (autonomation) (Correct answer)
- Kanban
- Heijunka
- Value stream mapping
Correct answer: Jidoka (autonomation)
Jidoka empowers machines or operators to stop a line immediately upon detecting a defect, embedding quality at the source.
Question 4: When a packaging process has a Cpk value of 0.85, this indicates that:
- The process is not centered and/or is producing output outside specification limits (Correct answer)
- The process is highly capable and centered
- The process meets Six Sigma standards
- Measurement system error is too high
Correct answer: The process is not centered and/or is producing output outside specification limits
A Cpk below 1.0 means the process is not capable of consistently meeting specifications, either due to excess variation or off-center mean.
Question 5: ISO 15378 is a quality management standard specifically developed for:
- Primary packaging materials for medicinal products (Correct answer)
- Food contact packaging materials
- Retail packaging structural design
- Transport packaging testing
Correct answer: Primary packaging materials for medicinal products
ISO 15378 applies GMP requirements to manufacturers of primary packaging materials for pharmaceuticals, based on ISO 9001.
Question 6: In statistical process control, an 'assignable cause' of variation is one that:
- Can be identified and eliminated through investigation (Correct answer)
- Is inherent to the process and cannot be economically removed
- Only appears in attribute data charts
- Results from sampling error
Correct answer: Can be identified and eliminated through investigation
Assignable (special) causes produce non-random signals on control charts and represent specific, identifiable sources of variation that can be corrected.
Question 7: A packaging quality team uses a 'fishbone diagram' during a root cause analysis session. The six typical 'bones' or categories in this tool are:
- Man, Machine, Material, Method, Measurement, Environment (Correct answer)
- Plan, Do, Check, Act, Sustain, Standardize
- Define, Measure, Analyze, Improve, Control, Verify
- Input, Process, Output, Feedback, Control, Supplier
Correct answer: Man, Machine, Material, Method, Measurement, Environment
The Ishikawa (fishbone) diagram organizes potential causes into six standard categories: Man, Machine, Material, Method, Measurement, and Environment (the 6 Ms).
