Industrial Problem Solving Flashcards

What does the term 'tolerance' mean in industrial manufacturing?

Answer: The acceptable range of variation in a dimension or measurement

Tolerance defines the acceptable upper and lower limits of variation for a measured dimension in manufactured parts.

A worker notices a recurring defect every 50th part produced. What type of issue does this most likely suggest?

Answer: A periodic or cyclical machine problem

A defect appearing at a consistent interval (every 50th part) suggests a periodic mechanical issue, such as a worn cam, gear, or die.

What does 'OEE' stand for and what does it measure?

Answer: Overall Equipment Effectiveness — a measure of how well a machine performs relative to its full potential

OEE (Overall Equipment Effectiveness) measures machine performance across availability, performance, and quality dimensions.

What is the correct sequence for a basic problem-solving process in an industrial setting?

Answer: Identify → Analyze → Fix → Verify

The standard problem-solving sequence is: Identify the problem, Analyze root causes, Fix the issue, then Verify the fix worked.

A Pareto chart is most useful for which of the following purposes?

Answer: Identifying the most significant causes contributing to a problem

A Pareto chart ranks causes by frequency or impact, helping teams focus on the 'vital few' causes that account for most problems.

What does it mean when a process is described as 'in statistical control'?

Answer: All variation in the process is due to common causes, with no special cause variation present

A process in statistical control has only common-cause (natural) variation; no unexpected special-cause events are influencing the output.
