A team is using a flowchart to document a process and encounters a step where two different outcomes are possible. Which symbol represents this decision point?
Answer: Diamond
A diamond shape in a flowchart represents a decision point where the process branches based on a yes/no or true/false condition.
When using a check sheet for data collection, which design feature is MOST important for reducing recording errors?
Answer: Pre-defining categories so collectors only need to make tally marks
Pre-defining categories minimizes ambiguity and cognitive load, allowing data collectors to quickly tally occurrences without interpretation errors.
Which of the following BEST describes the purpose of stratification in quality data analysis?
Answer: Separating data into subgroups to identify patterns by source, shift, or machine
Stratification divides data into meaningful subgroups (e.g., by machine, operator, shift) to reveal patterns that may be hidden in aggregated data.
A run chart shows seven consecutive data points trending steadily downward. What is the MOST appropriate conclusion?
Answer: A special cause may be present and investigation is warranted
Seven or more consecutive points in a single direction (trend) on a run chart is a non-random pattern indicating a likely special cause that should be investigated.
Which quality improvement tool would BEST help a team reach consensus on the root cause of a problem after generating many possible causes through brainstorming?
Answer: Multivoting
Multivoting allows a team to collectively narrow down a large list of ideas by giving each member multiple votes, efficiently building consensus.
In PDCA, after a successful 'Check' phase confirms the solution works, the NEXT step is to:
Answer: Standardize the solution and train staff (Act phase)
The Act phase involves standardizing successful changes, updating procedures, and training personnel so improvements are sustained.
A team wants to determine whether there is a relationship between ambient temperature and the number of surface defects on a product. Which tool should they use?
Answer: Scatter diagram
A scatter diagram is the appropriate tool for analyzing the potential relationship between two continuous variables such as temperature and defect count.
