Question 1

In a tolerance design process,a _____ is needed to account for engineering uncertainty regarding the maximum variation allowable and compatibility with satisfactory product performance.
A)process variation limit
B)covariance factor
C)factor of safety
D)capacity variance

Accepted Answer

A factor of safety is necessary in a tolerance design process to account for any uncertainties that arise due to variations in the manufacturing process or materials. This factor provides a cushion to ensure that the final product will meet performance requirements even in the presence of these uncertainties. A covariance factor is used to take into account the correlation between two variables, and is not directly related to tolerance design. A process variation limit and capacity variance are not directly related to accounting for engineering uncertainty in a tolerance design process.

Question 2

Under QFD,all operations of a company are driven by:
A)intraorganizational consensus.
B)the voice of the customer.
C)management directives.
D)Six Sigma principles.

Accepted Answer

QFD, or Quality Function Deployment, is a methodology used to ensure that a company's products or services meet the needs and expectations of its customers. Central to QFD is the concept of the "voice of the customer," which refers to gathering and incorporating customer feedback into all aspects of a company's operations, from product design to customer service. Therefore, under QFD, all operations of a company are driven by the voice of the customer, making choice B the best option.

Accepted Answer

Quality function deployment (QFD) is a planning process that helps in the integration of the voice of the customer by guiding the design, manufacturing, and marketing of goods. It helps in identifying customer needs and expectations and translates them into specific product features and characteristics that can be measured and prioritized. QFD ensures that customer requirements are met throughout the entire product development process. The other options listed are related to quality management but not specifically focused on integrating the voice of the customer throughout the organization.

Question 10

_____ uses a type of matrix diagram to present data and information.
A)Quality function deployment
B)Concept engineering
C)DMADV
D)Concept development

Accepted Answer

Quality function deployment (QFD) uses a type of matrix diagram, known as a House of Quality, to present data and information. The House of Quality matrix is used to identify and prioritize customer needs and wants, as well as to ensure that these needs are met in the design and development process.

B)Design, Monitor, Assess, Deploy, and Verify.
C)Develop, Measure, Assess, Deliver, and Verify.
D)Define, Measure, Analyze, Design, and Verify.

Accepted Answer

DMADV stands for Define, Measure, Analyze, Design, and Verify, which is a Six Sigma method used for designing new processes, products, or services to achieve higher levels of performance and quality. Option A and B are incorrect as they include incorrect phases, and option C includes "deliver" instead of "design."

Question 12

_____ is an emerging concept that includes many design-related initiatives such as concurrent engineering,design for manufacturability,design for assembly,design for environment,and other "design for" approaches.
A)Design for optimization
B)Design for manufacturability
C)Design for environment
D)Design for excellence

Accepted Answer

The concept described in the question is commonly referred to as "Design for Excellence" (DFX). This approach seeks to incorporate various design-related initiatives, such as concurrent engineering, design for manufacturability, design for assembly, and design for environment, to improve the overall design process and product performance. Therefore, option D, "Design for excellence," is the best choice.

Question 13

The first question one must ask during concept development is:
A)What is the product (good or service)intended to do?
B)What should be the USP (unique selling proposition)of the product/service?
C)What is the profile of the target customer?
D)How can the product/service fit into existing processes?

Accepted Answer

Understanding the purpose and intended function of the product/service is the fundamental starting point for concept development. The other options are also important considerations, but they come after this initial question has been addressed.

In the QFD process,a _____ forms the basis for a quality control plan delivering those critical characteristics that are crucial to achieving customer satisfaction,as specified in the last house of quality.
A)control point
B)key process
C)quality parameter
D)key result area

Accepted Answer

A control point is a point in a process where a measurement or observation is made to ensure that the process is operating as intended. In the QFD process, control points are used to monitor the critical characteristics that are crucial to achieving customer satisfaction.

Question 20

Concept development is a highly creative activity that can be enhanced by such techniques as _____ and _____.
A)process mapping; modeling
B)IQ assessments; self-assessments.
C)training; brain-mapping
D)brainstorming ; Brainwriting

Accepted Answer

Brainstorming and Brainwriting are both techniques that encourage free-flowing ideas and creativity, which can be instrumental in concept development. Process mapping and modeling are more structured techniques that might be helpful in other aspects of development, such as project management. IQ assessments and self-assessments might be useful in understanding individual strengths and weaknesses, but may not directly contribute to creative concept development. Similarly, training and brain-mapping could be helpful in understanding concepts but are not techniques that directly stimulate creativity.
