instead of vegetable oil and forgets to set a timer. The cake recipe has probably been developed
using:
A) value analysis.
B) the development funnel.
C) robust design.
D) Design for the Environment.
10) A revision to a drawing or design released by designers to correct a part is called a(n):
A) engineering change.
B) part mod.
C) tweak.
D) lock-in.
11) ________ refers to the ease with which critical components or functions can be tested during
production.
12) The unexpected expenses associated with overhead and engineering change notices are
________.
13) What are the four reasons that a company might develop new products and services?
14) What are robust design, testability, and serviceability and how are they related?
Learning Objective 15-2
1) The concept development phase addresses the feasibility of a product or service.
2) In the planning phase, the operations and supply chain function develops initial cost estimates
and identifies key supply chain partners.
3) In the launch phase of product development it is typically the marketing department’s
responsibility to fill the downstream supply chain.
4) The development funnel demonstrates that while initial conceptual development takes a long
time, product design can progress quickly through the final phases of development.
5) Products developed using a concurrent engineering process can be developed more quickly
than those using a sequential development process.
6) Customers are often brought in to lend their thoughts during the:
A) concept development phase.
B) planning phase.
C) design and development phase.
D) commercial preparation phase.
7) The feasibility of a product or service is evaluated during the:
A) planning phase.
B) evaluation phase.
C) launch phase.
D) concept development phase.
8) The operations and supply chain functions develop detailed process maps of the operations
and supply chain flows and test new processes in the:
A) concept development phase.
B) planning phase.
C) design and development phase.
D) commercial preparation phase.
9) Which of the following occurs during a sequential development process?
A) Activities in different development stages overlap with one another.
B) Constant communication is required between participants at various stages in the
development effort.
C) Prototypes can begin before product characteristics are finalized.
D) The development funnel process takes place.
10) The company begins to address the feasibility of a product or service in the ________ phase
of the development process.
11) The ________ is the process whereby many ideas are considered at the concept development
phase but few ideas make it to the commercial development and launch phases.
12) ________ allows activities in different development stages to overlap with one another.
13) What are the phases of the product development process and what takes place in each?
14) What is the operations and supply chain function responsible for in each of the product
development phases?
Learning Objective 15-3
1) Presourcing is the process of preapproving suppliers for specific commodities or parts.
2) An example of black box design would be a producer of automotive brakes working at the
design table with an automobile manufacturer through all phases of product development.
3) The development of specifications for the manufacturing equipment needed to make the
product is the responsibility of:
A) engineering.
B) marketing.
C) accounting.
D) purchasing.
4) The process of preapproving suppliers for specific commodities or parts is known as:
A) screening.
B) presourcing.
C) presaging.
D) certifying.
5) In high tech firms, the group most likely to be responsible for the success of a product
development process is:
A) scientists and engineers.
B) marketing.
C) consumers.
D) accounting/finance.
6) In most firms, the group that addresses the questions of who buys the company’s product and
what they are likely to pay is:
A) scientists and engineers.
B) marketing.
C) consumers.
D) accounting/finance.
7) In most firms, the group that addresses the cost and performance information companies need
to make good business decisions is:
A) scientists and engineers.
B) marketing.
C) consumers.
D) accounting
8) In most firms, the group that tracks forecasts of prices and long term supplies of key materials
is:
A) suppliers.
B) marketing.
C) purchasing.
D) accounting/finance.
9) Your supplier works closely with you to jointly design a product in:
A) gray box design.
B) black box design.
C) white box design.
D) red box design.
10) Black box design works best when:
A) the manufacturer is the expert.
B) the supplier is the expert.
C) the design is innovative.
D) the product is simply being redesigned, not newly developed.
11) ABC Corporation knew that XYZ Industries could provide the casings needed for their new
line of typewriters as they had for the previous generations of typewriters. Therefore, they
designated XYZ as the supplier for that key element, a practice known as ________.
12) In ________, the supplier works with the customer to jointly design the product.
Learning Objective 15-4
1) Quality function deployment can be used to show linkages between customer requirements
and product characteristics.
2) The roof of the house of quality displays conflicts between the voice of the customer and
product characteristics and permits designers to rapidly identify trade-offs.
3) The output from the first QFD matrix that feeds into the second QFD matrix is the product
characteristics information.

5) Companies can reduce the time and cost of developing new products and reduce the cost of
final products by using parts standardization.
6) The oil could be changed at the push of a button without dirtying your hands or peering
underneath the new Chrysler Crepitus. This is an important achievement in their Design for Six
Sigma program.
