Lean Six Sigma Black Belt Practice Test

_____________ is a concept in quality that means mistake-proofing. It can be electrical, mechanical, procedural, visual, human or any other form that prevents incorrect execution of a process step. It helps people and processes work right the first time.

What is the definition of a stakeholder?

Which of the following actions is not so typical for the lean process?

Six sigma equates to:

The amount of measurement variation introduced by a measurement system. It consists of the measuring instrument itself and the individuals using the instrument.

The DMAIC Method.  Which stage does this identify?

Identify and state the practical problem.

The number of defect-free units produced divided by the number of total units going into the process.

__________ is a sampling from a population in which the selection of a sample unit is based on chance, and every element of the population has a known, non-zero probability of being selected.

Defining a process:

The most common tool to help define a process is called a _______. It helps team members determine process activities, stakeholders, and boundaries.

Lean Six Sigma uses an improvement method called:

Change Management
Define this type of change:

A radical change and a significant shift away from the way currently things are done.

The quality plan specifies the control limits of a process; the size of the range between those limits is the:

_________ is a measure of the distance between the actual value and the average value of a part. It occurs when the survey sample does not accurately represent the population.

Data that cannot be broken down into smaller units. Only a finite number of values are possible. It has one set of values such as pass or fail or yes or no.

Problem Solving Strategy: Y=f(x)

Represents the desired outcome, result, or goal you want to achieve.

The total cost when you add up the cost of all the prevention and inspection activities you are going to do on your project.

Six Sigma Processes:

This is the single individual or group with responsibility for the end-to-end process.

Defined as “A measure of the changes in the output of a process over a period of time.”

When variation is produced by the system itself it is known as:

What can unmanaged expectations cause?

Five S (5S): Sort, Straighten, Shine, Standardize, and Sustain

What stage of 5S does this statement describe:

Make sure a regular cleaning and maintenance schedule is in place

What does this image represent?

• Define the problem statement
• Define the project scope and reference data
• Identify and confirm the project stakeholders, team members, and timeline for the project

These are all part of what document?

Which belt-level training should this employee receive:

This employee will have no direct contact with a project. They will not be providing any assistance to the team and have only worked for the organization for 90 days.

Part of the project charter, this identifies the money that can be saved and helps establish how the project aligns with the organization’s strategies. It also states how the six sigma project will help the organization reach its goals.

A statistical technique for analyzing experimental data. It subdivides the total variation of a data set into meaningful component parts associated with specific sources of variation in order to test a hypothesis on the parameters of the model or to estimate variance components.

With Lean Six Sigma, using pull philosophy results in:

This project team member guides the team, provides organizational support, resources, and removes roadblocks.

Six Sigma is all about finding those few significant changes that can impact outcomes of production.  ___________ help you determine if a factor is trivial or significant.

What does the “M” in the SMART acronym stand for?

In Lean, what is ‘Gemba’?

Used to understand the effects of the factors and interactions that affect the output of a process.

What is the first phase of Kaizen?

The DMAIC Method.  Which stage does this identify?

Validate the practical problem by collecting data

The demand rate of your external customer for your products. It signifies how fast you have to make products to meet your customer demand.

The DMAIC Method.  Which stage does this identify?

Convert the statistical solution to a practical solution

Used to determine the strength of a relationship between data output and input.

A common mistake is trying to improve a process by adjusting it when it does not need adjustment. The term for this mistake is called:

These Six Sigma project members participate as subject-matter experts (SMEs) in their area of work.

Used in Six Sigma to screen for potential causes of a problem. The test calculates the probability that an observed difference between two or more sets of data can be explained by random chance alone and not a fundamental difference between the underlying sample populations that the samples came from. The p-value is most often used to represent this.

Change Management
Define this type of change:

Change evolves slowly and follows a clear path. The changes are minor and people can cope with them.

The most common type of Lean waste is:

Sometimes improvement projects fail. It’s often because they are too focused on:

Concept that means items are processed and moved directly from one processing step to the next, one piece at a time.

Six Sigma reduces costs and waste by determining the:

Six Sigma requires _________ across the business and its leadership for the project to make changes based upon measurements.

This analysis is looking at how much your quality activities will cost, versus how much you will gain from doing them.

____________ is a comparison and cross-referenced review of similar processes within associated businesses.

At the Six Sigma level, a business process produces only 3.4 defects per million opportunities. How many errors are produced at the Five Sigma level?

What is the final step of DMAIC method?

The DMAIC Method

This stage is where the starting point metrics are recorded to baseline the current performance level.

In project management, what does “resources” mean?

Lean Six Sigma is the primary tool for achieving:

Six Sigma Statistics
There are 3 types of averages most commonly used in statistics: the mode, median, and mean average.

What is the median of this number set?

10, 10, 20, 40, 70

During the planning phase of a project, who defines the scope, time, cost, and quality?

Lean production was developed by:

Activities that do not create value to the external customer but are required to maintain business operations.

What is the definition of a project manager?

Lean Six Sigma can help the healthcare system with:

This process is different from DMAIC as it is used for designing a completely new product or process that meets customer specifications.
