Free Lean Six Sigma Yellow Belt Certification Assessment Questions and Answers

Question 1

What is the BEST approach to raise an automated assembly machine's operational availability if it is currently insufficient to satisfy a rise in customer demand?

Accepted Answer

Reduce breakdowns and delays

Answer

Operational availability refers to the percentage of time a machine is ready and able to perform its intended function. Breakdowns and delays directly reduce this availability, as the machine is idle and not producing. Therefore, the most effective way to increase an automated assembly machine's operational availability and meet rising demand is to minimize these interruptions, ensuring it spends more time actively producing.

Question 2

Except for, all of the following are advantages of control programs.

Accepted Answer

Helps to analyze and eliminate potential x's

Answer

Control programs in Lean Six Sigma are implemented to sustain improvements and prevent processes from regressing after a project. Their purpose is to monitor key metrics, ensure stability, and define mitigation actions when deviations occur. Analyzing and eliminating potential root causes ('x's) is typically the focus of the Analyze and Improve phases of a DMAIC project, not the ongoing function of a control program.

Question 3

Which type of muda results from working longer hours than necessary, scheduling more work than is required, or spending excessive amounts of resources?

Accepted Answer

Over-Processing

Answer

Over-Processing is one of the eight wastes (Muda) in Lean methodology. It refers to performing unnecessary work, adding features, or expending resources beyond what the customer actually requires or values. Working longer hours, scheduling excessive work, or using too many resources all fall under this category, as they consume time and effort without adding proportional value.

Question 4

Fundamentals for Your Lean Journey: Kaizen Express

Accepted Answer

By Toshiko Narusawa and John Shook

Answer

"Kaizen Express: Fundamentals for Your Lean Journey" is a well-regarded book in the Lean community. It was authored by Toshiko Narusawa and John Shook, both prominent figures associated with the Lean Enterprise Institute. The book serves as a practical guide to understanding and implementing Kaizen principles for continuous improvement.

Question 5

For the Process Owner, a Belt develops a Control Plan when she completes an LSS project. The _______________ section of the Control Plan specifies what should be done when the KPIs show signs of potentially straying outside of acceptable bounds.

Accepted Answer

Response Plan

Answer

A Control Plan is a critical document in Lean Six Sigma that outlines how to maintain process improvements over time. The 'Response Plan' section specifically details the predefined actions and steps that should be taken by the Process Owner when Key Performance Indicators (KPIs) show signs of deviating or straying outside of acceptable operational limits. This ensures prompt corrective action to maintain process stability.
