15% rejects. - correct answer FALSE
The house of quality is a means of integrating the voice of the customer into the product
or service development process.
Concurrent Engineering is another term for sequential development. - correct answer
FALSE
Concurrent engineering involves simultaneous product and production development.
One of the main advantages of standardization is that it increases the potential variety
of products - correct answer FALSE
Standardization reduces the variety of products.
A disadvantage of standardization is the possibility of standardizing designs too early,
which may make it difficult to modify in the future. - correct answer TRUE
Standardization locks firms into designs that aren't easily changed.
Reducing consumer choices makes service more efficient. - correct answer TRUE
Efficiency comes from the standardization that results from reduced consumer choices.
Modular design increases costs of purchasing and controlling inventory compared to
non-modular. - correct answer FALSE
Modular designs make inventory management easier and cheaper.
Product failures can be easier to remedy with modular design. - correct answer TRUE
Modular designs make it easy to change only portions of the design.
One motivation for an organization to redesign its product or service is to avoid the
alternative of downsizing the organization. - correct answer TRUE
The threat of downsizing often spurs product or service redesign.
A major benefit of Computer Aided Design (CAD) is the increased productivity of
designers. - correct answer TRUE
CAD tends to greatly increase designers' productivity.
Most of the time what is called product or service design is actually a redesign of an
existing product or service. - correct answer TRUE
Usually the core product or service remains relatively unchanged even though other
features are modified or enhanced.
,A service blueprint is quite similar to an architectural drawing. - correct answer TRUE
A service blueprint shows the basic customer and service actions involved in a service
operation.
The process of dismantling and inspecting a competitor's product to discover product
improvement is called benchmarking. - correct answer FALSE
Dismantling and inspecting a competitor's product to discover product improvement is
called reverse engineering.
To save money, it is essential that designers revise the production capabilities to meet
the requirements of the new products. - correct answer FALSE
Saving money requires designers to ensure that new products can be produced using
existing production capabilities.
Many US manufacturers are now shifting their focus from products to both product and
process improvements. - correct answer TRUE
Both product and process must be considered in the product/service design question.
Applied research has the objective of achieving commercial applications for new ideas. -
correct answer TRUE
Applied research is aimed at commercializing basic research.
Basic research is done with the expectation that discoveries will have near-term
commercial application - correct answer FALSE
Basic research is done with no clear expectations regarding commercial application.
"Design for production" takes into account the capabilities of the organization to produce
or deliver a given product or service. - correct answer TRUE
Design for production is important to ensure that product or service design decisions are
feasible.
Consumers tend to resist purchasing products containing recycled materials. - correct
answer FALSE
Consumers are beginning to respond positively when informed that their purchases
contain recycled materials.
"Concurrent engineering" brings people concerned with manufacturing into the design
phase earlier than in the "over-the-wall" approach. - correct answer TRUE
Concurrent engineering people concerned with manufacturing are actively engaged in
the design phase.
"Concurrent engineering" means that at least two engineers are involved in product
design at the same time. - correct answer FALSE
Concurrent engineering means that engineers, marketing, manufacturing and
purchasing personnel often are jointly involved in the product design.
,One approach to extending a product's life cycle is to promote alternate uses of the
product. - correct answer TRUE
Alternate uses extend product life cycles.
"Quality Function Deployment" is a structured approach that guarantees that the highest
quality product or service will be designed. - correct answer FALSE
Quality Function Deployment ensures that the voice of the customer is integrated into
the product or service design question.
Product liability means that a manufacturer is liable for any injuries and damages
caused by a faulty product because of poor workmanship or design. - correct answer
TRUE
Product liability is a serious issue for manufacturers.
The process of dismantling and inspecting a competitor's product to discover
improvement is called reverse engineering. - correct answer TRUE
Reverse engineering is a legitimate means of evaluating the competitive landscape.
Research and development (R&D) refers to organized efforts that are directed toward
increasing scientific knowledge and product (or process) innovation. - correct answer
TRUE
Product or process innovations often result from deliberate R&D programs.
Standardization refers to the extent to which there is absence of variety in a product,
service, or process. - correct answer TRUE
Standardization reduces variety and leads to greater efficiency.
Re-manufacturing refers to removing some of the components of old products and
reusing them in new products. - correct answer TRUE
Re-manufacturing is a way of increasing sustainability.
The demand for a product and the rate of technological change have significant impact
on the length of a given phase of the product life cycle. - correct answer TRUE
How long a product stays in a particular phase of its life cycle depends greatly on the
rate of technological change.
Robust design describes a product that will perform satisfactorily so long as it is used in
a very narrow range of conditions. - correct answer FALSE
Robust designs perform satisfactorily across a wide range of conditions.
Taguchi design methods involve identifying the optimal operating or environmental
conditions for a given product. - correct answer FALSE
Taguchi design methods involve designing products that are relatively insensitive to
environmental factors.
, Quality function deployment (QFD) is based on a set of standards which relate
customer requirements to company capabilities. - correct answer FALSE
QFD relates customer requirements to product designs and the capabilities necessary
to carry these designs out.
The quality function deployment (QFD) matrices are often referred to as the "House of
Quality" because, when completed, they "house" all of the customer's quality
requirements. - correct answer FALSE
QFD matrices link customer requirements with other product/process design elements.
Service design often must take into account the degree of customer contact required. -
correct answer TRUE
Customer contact is a critical service design issue.
Reliability refers to the ability of a product to perform its intended function under normal
conditions. - correct answer TRUE
Greater reliability translates into a greater likelihood of the product working in normal
conditions.
Applied research is the major R & D effort of business organizations because of the
desire for commercial applications. - correct answer TRUE
Most business organizations focus on applied rather than basic research.
Commonality of components is beneficial for manufacturing but not for services. -
correct answer FALSE
Services can benefit from commonality in service elements.
Standardization can at times lead to serious difficulties and competitive struggles,
particularly when systems are running under different conditions. - correct answer
FALSE
It is the lack of standardization that can at times lead to serious difficulties and
competitive struggles.
The term failure as applied to reliability means that a part or item does not function at
all. - correct answer FALSE
Failure means that the part or item does not function as it should.
Reliability can be defined in terms of a particular point in time or in terms of length of
service. - correct answer TRUE
Reliable designs can be counted on to work over time.
Reliability can be improved by the use of backup components. - correct answer TRUE
