Which technique uses a fishbone diagram to identify root causes of a process defect?
Answer: Ishikawa (Cause-and-Effect) Analysis
The Ishikawa (fishbone) diagram visually maps categories of potential causes leading to a specific defect or problem.
In process optimization, what does OEE stand for?
Answer: Overall Equipment Effectiveness
OEE (Overall Equipment Effectiveness) measures availability, performance, and quality to assess manufacturing productivity.
A manufacturing plant reduces changeover time from 4 hours to 45 minutes using SMED. What does SMED stand for?
Answer: Single-Minute Exchange of Die
SMED (Single-Minute Exchange of Die) is a lean technique aimed at reducing setup and changeover times to under 10 minutes.
Which process improvement model follows the sequence Define, Measure, Analyze, Improve, Control?
Answer: DMAIC
DMAIC is the core Six Sigma problem-solving framework used to improve existing processes systematically.
What is the purpose of a Process Capability Index (Cpk)?
Answer: Quantify how well a process fits within specification limits
Cpk measures how centered and spread out a process is relative to its upper and lower specification limits.
In value stream mapping, which symbol typically represents a push production system?
Answer: Push arrow (straight arrow)
A straight push arrow in VSM indicates that material is pushed downstream regardless of actual downstream demand.
A process engineer wants to simultaneously test the effect of three factors at two levels each. Which experimental design is most efficient?
Answer: Full factorial 2³ design
A full 2³ factorial design tests all combinations of three factors at two levels, capturing main effects and interactions in 8 runs.
