Lean Six Sigma Black Belt Practice Test

__________ 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.

A tool used to analyze a process for delays:

A cyclic process for planning and testing improvement activities prior to full-scale implementation.

Lean Six Sigma can help the healthcare system with:

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

Defines the scope of the project and breaks the work down into components that can be scheduled, estimated, and easily monitored and controlled. You subdivide a complicated task into smaller tasks, until you reach a level that cannot be further subdivided.

____________ uses a system of signal cards that is simple, yet shows someone that something in a process needs attention.

The most common type of Lean waste is:

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

The DMAIC Method.  Which stage does this identify?

Validate the practical problem by collecting data

What does GENCHI GEBUTSU mean?

The DMAIC Method

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

_______ is the variation in the operation of a process not caused by the end customer. It is the Irregular, Inconsistent, Uneven, and Unbalanced work on machines.

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

What is the definition of a stakeholder?

Six Sigma reduces costs and waste by determining 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.

What is the definition of a project?

Problem Solving Strategy: Y=f(x)

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

Six Sigma Processes:

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

What is the definition of a project manager?

A formal document used to summarize key deliverables and information for a Six Sigma project.

Which statement is true about Lean Six Sigma?

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

CTC, Critical to Cost
CTS, Critical to Safety
CTP, Critical to Process

These measures all fall under what characteristic?

Lean production was developed by:

This is used to test whether a sample is drawn from a population that conforms to a specified distribution. One of the most widely used probability distributions in inferential statistics, notably in hypothesis testing and in construction of confidence intervals.

In Lean, what is ‘Gemba’?

This review is conducted after each stage of the DMAIC process.

Problem Solving Strategy: Y=f(x)

Represents the function or process applied to the variables, by which they are modified, changed, or altered.

What is the final step of DMAIC method?

The DMAIC Method.  Which stage does this identify?

Identify and state the practical problem.

• 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?

Failure Modes & Effects Analysis (FMEA):

The value assigned to the severity and occurrence of each potential failure on scale of 1 to 10 or low to high.

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.

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

Six sigma equates to:

These identify what may go wrong in a plan under development. Once possible issues are identified, prevention controls and countermeasures can be developed to prevent the problems.

All activities that create value for the external customer.

With Lean Six Sigma, using pull philosophy results in:

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

Planning all the intermediate and final deliverables that you and your team will produce over the course of the project. Deliverables include everything that you and your team produce for the project. It is recorded in the project charter. This is called:

When building your project schedule-timeline, what should you never do?

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.

Lean helps with the following:

Lean Six Sigma can be used in which industries?

Which employees should be trained when an organization initiates a Six Sigma improvement policy?

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

________ is a term used to denote variance from the mean average of an event.

The sum of internal and external failures. It is measured differently depending on the industry.

Which plan ensures that everyone involved in the project stays up to date, and that information is shared appropriately?

Lean Six Sigma is the primary tool for achieving:

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

What stage of 5S does this statement describe:

Remove what is not needed

_____________ 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.

The DMAIC Method.  Which stage does this identify?

Confirm and test the Statistical solution

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

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.

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

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

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:
