LEAN Six Sigma Yellow Belt : Control Phase : Practice Exam

#1. What is the primary goal of the Control phase?

To implement solutions

To measure baseline performance

To sustain improvements and prevent regression

To identify root causes

#2. What is regression in the context of process control?

A reduction in process capability

An increase in customer satisfaction

A return to previous ineffective process performance

An improvement in process standards

#3. Which tool is commonly used to track performance trends over time?

Fishbone diagram

Control chart

Pareto chart

5 Whys

#4. What is the purpose of a handover in the Control phase?

To finalize project goals

To transfer ownership and accountability to process owners

To measure process variation

To identify root causes

#5. What is the main purpose of monitoring tools in the Control phase?

To analyze defects

To sustain improvements and detect deviations

To collect baseline data

To implement process changes

#6. What does ‘process standardization’ aim to achieve?

Eliminating all process defects

Reducing process variation

Ensuring consistent application of new processes

Measuring customer satisfaction

#7. What is the first step in ensuring ongoing process control?

Handover to stakeholders

Monitoring process performance

Defining process standards

Creating a project charter

#8. What is included in a project close-out report?

Root cause analysis results

A summary of improvements, lessons learned, and final metrics

A control chart

Baseline performance metrics

#9. What is a key benefit of standardizing new processes?

It eliminates the need for training

It ensures process performance remains consistent

It guarantees 100% defect-free results

It reduces customer complaints

#10. Why is it important to train employees on new standardized processes?

To ensure ongoing process adherence

To measure process performance

To identify process defects

To validate root causes

#11. Why is documentation critical in the Control phase?

To create a new project charter

To provide a reference for maintaining improvements

To identify root causes

To measure process variation

#12. Which of the following is a key element of process control?

Brainstorming improvement ideas

Regular monitoring of key metrics

Defining project scope

Creating process maps

#13. What does the lower control limit in a control chart indicate?

The target value for the process

The minimum acceptable level of process variation

The point at which the process is out of control

The total number of defects

#14. How can you prevent regression in a newly improved process?

By eliminating all defects

By implementing regular monitoring and controls

By redesigning the process

By analyzing past performance

#15. What is a control chart used for?

To identify potential root causes

To monitor process performance over time

To brainstorm improvement ideas

To implement process changes

#16. What is a key component of ensuring ongoing process control?

Analyzing root causes

Establishing feedback loops for continuous monitoring

Redesigning the process

Revisiting project objectives

#17. What is an upper control limit in a control chart?

A target value for defects

The maximum acceptable value of natural process variation

A measure of process capability

The total number of defects

#18. What is the purpose of documenting new processes?

To provide a detailed analysis of defects

To standardize changes and ensure consistency

To identify further improvement opportunities

To create process maps

#19. What does ‘closing out a project’ involve?

Continuing root cause analysis

Completing the project handover and documenting outcomes

Identifying potential improvement areas

Revising the project charter

#20. What is the purpose of an X-bar chart?

To measure process capability

To monitor the average performance of a process

To track individual defect occurrences

To identify root causes
