1. Which engineering drawing notation system is the standard used in US manufacturing for communicating geometric tolerances? → GD&T (Geometric Dimensioning and Tolerancing)
2. Which technique uses a fishbone diagram to identify root causes of a process defect? → Ishikawa (Cause-and-Effect) Analysis
3. Which lean concept refers to the ability of a machine to detect an abnormality and stop automatically? → Jidoka
4. What is a safety audit? → An evaluation of workplace safety procedures and hazard identification.
5. What does 'labor efficiency ratio' measure in manufacturing workforce management? → Actual output produced per labor hour versus the standard expected output
6. In lean manufacturing, what does 'standard work' mean in relation to workforce management? → Documenting the most efficient known method for each task to ensure consistency
7. What is a key challenge in supply chain management? → Managing risks and disruptions.
8. Which of the following best describes a 'Brownfield' site in the context of environmental compliance? → A previously developed property with potential contamination from prior use
9. A pull system triggers production based on which signal? → Actual downstream customer or process demand
10. In a Programmable Logic Controller (PLC), what is the primary function of the input/output (I/O) module? → Interfaces sensors and actuators with the CPU
11. The NIOSH Lifting Equation is used to calculate the Recommended Weight Limit (RWL). What does a Lifting Index (LI) greater than 1.0 indicate? → The lifting task may pose an increased risk of musculoskeletal injury
12. A drum-buffer-rope (DBR) scheduling system places the 'rope' to synchronize which part of the production system? → Material release at the front of the plant to the drum's pace
13. What is the primary ethical obligation of a CMS professional when a conflict of interest arises during lean manufacturing & waste reduction activities? → Disclose the conflict to all relevant parties and recuse from the decision if necessary
14. A manufacturer wants to expand capacity temporarily without capital investment. Which option is NOT a short-term capacity adjustment? → Building a new production facility
15. Which electrical safety lockout/tagout (LOTO) step must occur FIRST before any equipment maintenance begins? → Identify all hazardous energy sources
16. A manufacturer uses a skills matrix. What is its primary function in workforce management? → Visualizing which employees are qualified for which tasks
17. A company shifts from a push-based to a pull-based supply chain. What is the key trigger for production in a pull system? → Actual customer demand or orders
18. What is the primary purpose of a skills matrix (competency matrix) in a manufacturing plant? → To visualize the skill levels of all workers across required competencies
