LEAN Six Sigma Yellow Belt : Analyze Phase : Practice Exam

#1. 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

#2. 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

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

What happened?

Who is responsible?

Why did this happen?

When did it occur?

#4. What is the primary focus of the 5 Whys analysis?

Identifying all potential solutions

Reducing process variation

Determining the root cause of a problem

Developing a new process

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

Categorical data

Qualitative and quantitative data

Descriptive data only

Continuous data only

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

It requires statistical analysis

It is quick and easy to perform

It guarantees a solution to the problem

It categorizes causes into groups

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

Possible causes of the problem

Steps in the process

Statistical data points

Final solutions

#8. Which tool is also known as a Fishbone diagram?

5 Whys

Control Chart

Ishikawa Diagram

Pareto Chart

#9. 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

#10. Which tool is best for categorizing causes into groups?

Control chart

Fishbone diagram

Histogram

Pareto chart

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

A tool to monitor process variation over time

A method for brainstorming solutions

A diagram for organizing data

#13. In a Fishbone diagram, where is the main problem written?

At the top of the diagram

Fishbone diagram

#15. 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

#16. What is the primary output of the Analyze phase?

An improved process

Validated root causes of the problem

A detailed project charter

Baseline performance metrics

#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. What is the primary goal of the Analyze phase?

To define the project scope
