Test review Six Sigma

By eliminating inefficiencies, waste and errors about ______ percent of healthcare costs could be saved.

25

Which of the following represents the number of Defects Per Million Outcomes associated when a process has been designed to meet Six Sigma standards.

3.4

A Risk Priority Number, RPN, is used to determine the ____________________ .

consequences or significance of a failure

The acronym VOC refers to the voice of the ___________

customer, which in healthcare reflects the voice of the patient.

Drawing a process flow diagram is usually associated with the ____________ phase of the lean-six sigma process.

dmaic

A Value Stream Map, also called a Process Flow Chart, is used in Six Sigma to analyze the variability of a process.

false

If designed properly, no more than a single histogram would be needed to find the root cause of a problem.

false

In most healthcare processes it is possible to eliminate all variation as long as the process has been designed using best practices.

false

Once a lean culture has been established it is usually self sustaining

false

Process Maps display a more detailed view of a process than do Value Stream Maps.

false

Special Cause variation is always present to some degree in any process.

false

The use of advanced imaging technology such as MRIs or CAT scans has reduced medical costs.

false

A large city center hospital monitors complaints through social media. There are seventeen categories associated with these complaints and include such categories as bad food, not as expected, long waits, and impersonal service. When creating a chart to rank these problems, it will be best to draw a ____________________.

histogram

The Taguchi Loss Function suggests that _______________ .

process shifts farther and farther away from its target, the cost to the company grows larger and larger

To monitor variation in a process, a sample of 10 items is taken. The range is calculated, and plotted on a quality control chart. Which of the following charts is suggested.

r-chart

The Root Cause refers to the process of drilling down through data to find the fundamental or most basic cause of a problem.

true

The concept behind the use of a control chart to monitor a process mean is that sample means taken from the process vary around the process mean. If the sample mean varies too far from the process mean, the process mean may have shifted and is in need of adjustment. In other words, the process may no longer be in-control

true

An unnecessary expenditure is classified in Lean as _______________.

waste

A sample of fifty patients is taken to determine their level of satisfaction with the nursing staff. A quality control chart will be designed to display their level of satisfaction on a scale of 1-100 where 100 implies complete satisfaction. Which of the following is not absolutely necessary when designing the chart.

x-bar chart

Establishing a ______________ is necessary when creating process control charts

All of the above

The term Value-Added in Lean refers to ____________________.

Customer perspective

Which of the following tools is used to anticipate how a process might fail to meet output expectations.

Failure Mode and Effects Analysis

Minimizing waste is not one of the objectives of a Six Sigma Analysis.

False

An Ishikawa Diagram is also known as a _________________

Fish

The methodology of Lean Six-Sigma moves though five steps. Which of the following is not one of them?

Install

The administrative office at an out patient clinic has found several reasons why there has been an increasing delay in receiving payment for services. They include: wrong bill sent, charges too high, patient not covered by insurance, patient not covered for this procedure, wrong procedure code, and incorrect patient information. Which of the following can be used to display the percentage that each problem contributes to the delay in receipt of payments.

Pareto chart

Which of the following is used to identify and display inputs, suppliers, outputs, process and customers?

Sipoc

Cost of Poor Quality (COPQ) only includes those costs that can be attributed to medical errors.

Target

A process output target or centerline is positioned below the __________ on a control chart.

Upper Control Limit

Which of the following terms represents the characteristics or specifications of the healthcare service necessary to meet the needs of the patient.

VOC

Which of the following defines the relationship between process inputs and outputs?

Y = fx

One of the objectives of Lean is to minimize or eliminate _________________ .

non value active
