Exam 13: Six Sigma Management and Lean Tools

The define, measure, analyze, design, and verify methodology pertains to ________.

Tolerance design occurs before parameter design and is used to manipulate variables.

DMAIC is very similar to Deming's PDCA cycle.

In the Six Sigma equation, Y = f(X), the variable X represents output or key business objectives.

When defining objectives in the analyze phase, you are attempting to determine what characteristics of the process need to be changed to achieve improvement.

A measurement systems analysis (MSA) is used to determine if measurements are consistent.

A Taguchi experiment is to be performed on the effects of lift, bore, stroke, and compression on engine performance with horsepower as the outcome variable. The factors were tested at each of the following levels in hopes of improving engine horsepower. Lift (L) 2.75 2.90 Bore (B) 0.10 0.30 Stroke (S) 0.50 0.60 Compression (C) 8.50 12.00 The following experiment was used and the results of all trials are as follows: Determine the best levels for each factor and state your conclusions.

The Pitman arm on a car costs $105 to repair. Compute the quality loss function for losses incurred as a result of deviation from a target where a tolerance of 10 plus or minus 0.8 is required and the root mean squared deviation (V) from the target is 0.25.

The XY matrix identifies ________ from a project you have mapped.

Which key player in Six Sigma is trained in basic quality tools and works in teams to improve quality on less critical projects?

Two important measures that are monitored in the process map are ________.

The Taguchi constant for flooring materials is known to be $13.33/cm sq. and the tolerance is 15 plus or minus 0.4. What is the cost to repair the flooring?

The Pitman arm on a car costs $105 to repair. Compute the quality loss function for losses incurred as a result of deviation from a target where a tolerance of 10 plus or minus 0.125 is required and the root mean squared deviation (V) from the target is 0.33.

Solution selection, solution implementation, control charts, and best practices are the tools used in the ________ stage of the DMAIC process.

The Taguchi constant for flooring materials is known to be $50/cm sq. and the cost to repair them is $300. What is the tolerance interval?

In Taguchi terms, ideal quality refers to an unattainable state of being.

________ get information from a variety of sources such as the voice of the business, the voice of the customer, and the voice of the employee for potential project ideas.

Noise factors are under the control of management.

The goal with a process map is to identify the sequence of steps in a process.

What is the Taguchi constant for a device that costs $250 to repair and a tolerance of plus or minus 2 mm with a mean squared deviation from the target of 0.2?
