Question 1

In RCA you are trying to uncover:&#10;A) The tree of relationships of causes and effects that lead to the condition or event you are studying.&#10;B) The single root cause of the event or condition&#10;C) What is the big thing you can fix?&#10;D) How would you communicate the bad effects to the team and others?

Accepted Answer

In RCA, the focus is on identifying the tree of relationships of causes and effects that lead to the condition or event being studied. This approach allows for a comprehensive understanding of the underlying factors contributing to the problem, which can inform effective solutions. The other options (B, C, D) are not the main focus of RCA.

Question 2

Why is it advantageous to have multiple points of view for a complete RCA?&#10;A) When you start you don't know the domain of the problem. It helps to have multiple expertise to uncover all the causes and effects. It also helps to have diversity to stimulate thought.&#10;B) You don't, because I mostly know best.&#10;C) They are there to make sure you don't spend the time blaming them!&#10;D) RCA is a sham process designed to make certain people look good.

Accepted Answer

Having multiple points of view allows for a more comprehensive understanding of the problem and its causes. It also brings diverse perspectives which can stimulate thought and provide different insights. The other choices are not valid as they either disregard the importance of multiple perspectives or make unfounded claims about RCA.

Question 3

In RCA who should perform the analysis&#10;A) People who have a problem and others from outside the area&#10;B) Engineers&#10;C) Managers&#10;D) People with extensive training in all forms of RCA

Accepted Answer

RCA (Root Cause Analysis) should be performed by the people who are directly involved with the problem to ensure an in-depth understanding of the issue, as well as others from outside the area to provide fresh perspectives and unbiased insights.

Question 4

In defect elimination what is it called when defects are deemed acceptable or look OK?&#10;A) Normalization of deviance&#10;B) Fundamental attribution error&#10;C) Regression to the mean&#10;D) Symbolic proto-conditioning

Accepted Answer

Normalization of deviance is the term used to describe the situation where defects are deemed acceptable or look OK, even though they are not. This happens when the team becomes accustomed to seeing defects and begins to view them as normal, rather than as opportunities for improvement. It is a dangerous situation as it can lead to a decrease in quality and an increase in defects over time.

Question 5

Lean Maintenance and Defect Elimination are.&#10;A) Closely related and often interchangeable&#10;B) Are hierarchical with DE being the parent and Lean being the child&#10;C) DE is run by operations and Lean by maintenance&#10;D) Ways to make more work

Accepted Answer

Lean Maintenance and Defect Elimination are closely related and often interchangeable. Both aim to improve efficiency and reduce waste in the maintenance process. However, Lean Maintenance focuses on the continuous improvement of processes to eliminate waste, while Defect Elimination is focused on identifying and eliminating the root causes of defects or failures.

Question 6

When making lists stay away from:&#10;A) All&#10;B) Things that require a lot of resources or depend on several people&#10;C) Issues that are personal&#10;D) Issues that have safety or MOC (management of change) consequences

Accepted Answer

All the options listed (B, C, D) are scenarios from which one should stay away when making lists, as they can introduce complications, privacy concerns, or safety risks.

Question 7

When choosing the DE or Lean project the major selection should be&#10;A) Chance of an easy success&#10;B) High visibility&#10;C) Return on investment&#10;D) Priority

Accepted Answer

The answer of When choosing the DE or Lean project...

Question 8

A good amount of DE and Lean activity as a percentage of hours is&#10;A) 1%&#10;B) 5%&#10;C) 10%&#10;D) 0%

Accepted Answer

The answer of A good amount of DE and Lean...

Question 9

If I propose a DE project to study the variation in voltage coming into the plant what would your advice be:&#10;A) That might be a great project, but it is not a DE project&#10;B) It might be good to look at the power factor too&#10;C) I'll bet the utility supplier would help&#10;D) Since we are seasonable we will have to study this for at least a year to really understand.

Accepted Answer

A DE (Data Engineering) project typically involves designing and building systems for collecting, storing, and analyzing data. Studying voltage variation is more related to electrical engineering or data analysis rather than data engineering.

Question 10

DE is primarily concerned with maintenance sources of defects.&#10;A) DE is concerned with all sources of defects.&#10;B) DE is more concerned with design issues and bad operators.&#10;C) DE doesn't care where the defect comes from as long as you eliminate it.&#10;D) DE stops where quality can take over to avoid stepping on toes

Accepted Answer

DE (Defect Elimination) is concerned with identifying and addressing all sources of defects, not just maintenance issues. This includes design flaws, operational errors, and any other factors that could lead to defects.
