LEAN Six Sigma Yellow Belt : Analyze Phase : Practice Exam

#1. When applying the 5 Whys, how many ‘Whys’ should you ask?

Exactly 5

As many as necessary to reach the root cause

Only until a solution is identified

No more than 3

#2. What does a Pareto chart help identify?

The root cause of a single problem

The most significant factors contributing to a problem

The sequence of process steps

The variation in process data

#3. What is the purpose of using basic statistical tools in the Analyze phase?

To implement solutions

To collect new data

To validate root causes and analyze patterns

To brainstorm process improvements

#4. What is Root Cause Analysis (RCA)?

A method for brainstorming ideas

A technique for identifying the fundamental reason for a problem

A statistical tool for data collection

A tool for controlling process changes

#5. Which statistical tool is often used to identify patterns in data?

Control chart

5 Whys

Pareto chart

Fishbone diagram

#6. What is a key advantage of using the 5 Whys technique?

It requires statistical analysis

Identifying all potential solutions

Reducing process variation

Determining the root cause of a problem

Developing a new process

#15. Which of the following is NOT a step in creating a Fishbone diagram?

Identifying the main problem

Brainstorming potential causes

Measuring process performance

Organizing causes into categories

#16. What type of data is typically used in cause-and-effect analysis?

Categorical data

Qualitative and quantitative data

Descriptive data only

Continuous data only

#17. Which of the following describes cause-and-effect relationships?

A detailed process map

A link between actions and their outcomes

A method for brainstorming solutions

A tool for identifying defects

#18. In a Fishbone diagram, what do the ‘bones’ represent?

Possible causes of the problem

Steps in the process

Statistical data points

Final solutions

#19. What question is repeatedly asked in the 5 Whys technique?

What happened?

Who is responsible?

Why did this happen?

When did it occur?

#20. What is the purpose of the 5 Whys technique?

To identify potential solutions

To determine the root cause of a problem

To measure process performance

To categorize defects
