Lean Six Sigma Yellow Belt Flash Cards

The total number of defects in a sample is 100 and the total number of units sampled is 1000. The DPU is ______ percent

10 because 100/1000=.10 or 10 percent.

A Six Sigma process will deliver no more than ________ defectives per million opportunities or outcomes.

3.4

The number of defective units produced by a machine beyond plus and minus six standard deviations from the mean would be fewer than ______ per million outcomes or opportunities .

3.4

The percent of outcomes that would be expected to occur above and below two standard deviations from the mean would be ______________.

5 percent

When setting an appropriate quality control level, a balance has to be established between quality and ____________ .

Cost

Six Sigma is a hard and fast rule for achieving quality.

False

There is no difference between Lean and Six Sigma.

False

In most situations higher quality output is associated with lower operational costs to the organization.

False - Higher quality, in most situations, cost more. Consider the Ben and Jerry's cas. Their high quality ice cream cost more to produce and sells for more in the supermarket.

Lean focuses on quality and consistency.

False - It focuses on the minimization of waste and delays.

A Four Sigma process would be expected to produce fewer than 3.4 defects per million opportunities.

False - It would produce significantly more than 3.4 defects per million opportunities.

Higher quality is always preferred, so every process must be designed to achieve a six sigma quality level at a minimum?

False - Quality at this level could be too costly to deliver given the price that could charged for the product or service.

Restaurants should set a Six Sigma standard for customer satisfaction.

False - This would mean 3.4 dissatisfied customers per million meals served. This would be a very costly goal to achieve.

The concept of Lean can be traced back to Motorola.

False It can be traced back to Toyota

A Fishbone Diagram is used to identify the Critical to Quality, characteristics of a product or service.

False is used to find the root cause of the problem.

In general, most organizations set their quality targets at ___________ Sigma.

Four

Lean is primarily limited to manufacturing processes.

It applies to all functional areas of business.

Which of the following is true about establishing a Six Sigma standard for a process.

It could be costly to achieve this level of quality

A well designed process should not produce output that varies around a process target. All output should be positioned exactly at the target.

Output variability is inevitable in all processes.

The likelihood that a process will complete all of the required steps without any failures or rejects is called _______________ .

Rolled Throughput Yield

Kaizen is a Japanese word suggesting _______________ .

continuous improvement

Sigma is a statistical term that measures ______________ .

variation

The Voice of the Customer is the same as the Voice of the Business.

They are different

A Six Sigma standard, at a minimum, would be appropriate for establishing controls in a nuclear power station.

True

If 100 units were processed through a manufacturing process but only 90 were completed, the First Time Yield would be 90 percent.

True

Lean primarily focuses on improving process efficiency.

True

Products and Services are delivered through processes.

True

The objective of Six Sigma is to deliver near-perfect products and services.

True

Value Added is defined from the customer's point-of view.

True

When the Cost of Poor Quality is zero, the product or service has achieved near perfection.

True

A process can be described mathematically as _________ .

Y=f(x)

Which of the following assures that the objectives of the organization are achieved when undertaking a Lean Six Sigma project?

Voice of the Business, VOB
