PPC Quality Control & Process Improvement 3 — Questions and Answers
Question 1: What does the 'PDCA' cycle stand for in the context of process improvement?
- Prepare, Draft, Confirm, Archive
- Plan, Do, Check, Act (Correct answer)
- Process, Document, Control, Audit
- Prioritize, Delegate, Communicate, Assess
Correct answer: Plan, Do, Check, Act
PDCA—Plan, Do, Check, Act—is a foundational continuous improvement cycle used to systematically test and refine processes.
Question 2: In Lean methodology, what term describes the elimination of non-value-adding steps in a patent prosecution workflow?
- Kaizen
- Kanban
- Muda elimination (Correct answer)
- Poka-yoke
Correct answer: Muda elimination
Muda is the Japanese term for waste; muda elimination focuses on removing steps that consume resources without adding value to the client or the output.
Question 3: How does a root cause analysis (RCA) benefit a patent paralegal department that is experiencing recurring docketing errors?
- It assigns blame to individual paralegals for errors
- It identifies the underlying systemic causes so corrective actions address the true source of the problem (Correct answer)
- It increases the number of quality checks per application
- It automatically corrects errors found in the docket
Correct answer: It identifies the underlying systemic causes so corrective actions address the true source of the problem
RCA uncovers the systemic or procedural root cause of recurring errors rather than treating symptoms, enabling durable corrective actions.
Question 4: A patent department holds a focused one-week event where staff collaboratively redesign the IDS filing workflow to reduce errors. This event is best described as:
- A Six Sigma black belt project
- A Kaizen event (Correct answer)
- A value stream mapping session
- A quality audit
Correct answer: A Kaizen event
A Kaizen event is a short, structured workshop where a cross-functional team rapidly improves a specific process, often within three to five days.
Question 5: Which tool is most effective for visually mapping all steps in a patent prosecution workflow from application intake to issuance?
- Pareto chart
- Ishikawa (fishbone) diagram
- Value stream map (Correct answer)
- Control chart
Correct answer: Value stream map
A value stream map shows every step, handoff, and wait time in an end-to-end process, making waste and bottlenecks visible.
Question 6: A paralegal department completes a process improvement project and achieves a 40% reduction in IDS processing time. What should be done to ensure the improvement is sustained?
- Inform only senior management and move on to the next project
- Update written standard operating procedures and train all staff on the new process (Correct answer)
- Rely on the team's memory of the new steps
- Archive the improvement report and revisit it in two years
Correct answer: Update written standard operating procedures and train all staff on the new process
Documenting the new process in updated SOPs and training all staff institutionalizes the improvement and prevents regression to old habits.
Question 7: Which quality tool would best help a patent paralegal team identify which type of filing error accounts for the majority of their total errors?
- Control chart
- Pareto chart (Correct answer)
- SIPOC diagram
- Affinity diagram
Correct answer: Pareto chart
A Pareto chart ranks error types by frequency, revealing the 'vital few' causes that account for most problems and guiding priority corrective actions.
