26. Which ISO standard deals with environmental management systems? — ISO 14001
27. What is the main benefit of using a 'control chart' compared to simply plotting data points? — It helps distinguish between common cause variation and special cause variation.
28. Which of the following is a common barrier to the successful implementation of TQM? — Lack of top management commitment
29. A Quality Circle is a small group of employees who meet regularly to discuss and solve work-related problems. What is a key characteristic of a Quality Circle? — Voluntary participation and self-management
30. Which of the following is a key characteristic of a 'Quality Circle'? — Small group of employees meeting voluntarily to solve work problems
31. The concept of 'Jidoka' (automation with a human touch) is often associated with Lean manufacturing and quality improvement. What does it enable? — Machines to stop automatically when a defect occurs
32. Which Six Sigma certification level typically works on smaller projects or assists Black Belts on larger ones, often part-time? — Green Belt
33. What is the core idea behind 'Customer Focus' in TQM? — Meeting customer needs and exceeding expectations
34. Which of the following is a common application of the 'X-bar chart' in SQC? — Monitoring the average of measurements within subgroups
35. What is the fundamental difference between 'quality assurance' and 'quality control'? — Quality assurance is about preventing defects; quality control is about detecting defects.
36. What is the fundamental goal of Kaizen? — Incremental, continuous improvement involving everyone
37. Which statistical method is often used to determine if there is a statistically significant difference between the means of two groups? — T-test
