Lean Tools
Q: What does 5S stand for in workplace organization?
A: Sort, Straighten, Scrub, Standardize, Sustain.
Q: What does FMEA stand for?
A: Failure Mode and Effects Analysis.
Q: What is the focus of Lean?
A: Eliminating waste and improving efficiency.
Q: What is the mean?
A: The average of all data points.
Q: What is the purpose of control charts?
A: To monitor process stability over time.
Q: What is the goal of Value Stream Analysis?
A: To map processes and identify waste for improvement.
Q: What is the purpose of FMEA?
A: To identify potential failures and prioritize actions to reduce risks.
Q: What is overprocessing in Lean?
A: Doing more work than necessary for a process or product.
Q: What is the mode?
A: The most frequently occurring value in a dataset.
Q: How do histograms help in process improvement?
A: They visualize data distribution to identify trends.
Q: What are the eight types of waste in Lean?
A: Transportation, Inventory, Motion, Waiting, Overproduction, Overprocessing, Defects, Skills.
Q: How is the Risk Priority Number (RPN) calculated?
A: By multiplying Severity × Occurrence × Detection.
Q: What is a kaizen blitz?
A: A focused, short-term effort to improve a process.
Q: What is standard deviation?
A: A measure of how spread out data is from the mean.
Q: What is takt time?
A: The rate at which a product must be produced to meet customer demand.
Q: What is the purpose of sorting in 5S?
A: To separate necessary items from unnecessary ones.
Q: What is the Severity of FMEA?
A: The seriousness of the impact of a failure.
Q: What is the PDCA cycle?
A: Plan-Do-Check-Act, a continuous improvement methodology.
Q: What is variance?
A: The square of the standard deviation.
Q: What is the difference between common cause and special cause variation?
A: Common cause variation is natural; special cause variation signals an issue.
Q: How does Lean differ from Six Sigma?
A: Lean focuses on eliminating waste, while Six Sigma reduces variation and defects.
Q: What does Detection refer to in FMEA?
A: The ability to catch a failure before it impacts the process.
Q: How do Lean and Six Sigma work together?
A: Lean removes waste, and Six Sigma improves process consistency.
Q: What is the purpose of inferential statistics?
A: To conclude a population based on sample data.
Q: What is the purpose of root cause analysis?
A: To identify and address the underlying cause of a problem.
