Answer

The 5 Whys technique involves repeatedly asking 'why' to drill down past symptoms to uncover the underlying root cause of a problem.

Question 2

Which of the following is a key difference between a flowchart and a process map?

Accepted Answer

A process map can show swim lanes with responsibilities; a flowchart typically does not

Question 3

Which statement BEST describes special cause variation in a process?

Accepted Answer

It is caused by identifiable, assignable factors outside the normal process

Special cause variation arises from specific, identifiable sources outside the normal system and causes unpredictable, non-random patterns in process output.

Question 4

A quality improvement team wants to prioritize which problems to solve first. They have limited time and resources. Which tool should they use FIRST?

Accepted Answer

Pareto chart

Answer

A Pareto chart helps teams prioritize by identifying the vital few problems that account for the majority of issues, enabling efficient resource allocation.

Question 5

What does a bimodal distribution in a histogram typically suggest about a process?
