D) to block out competitors
6) How might a company benefit from its own new product?
A) by increasing product complexity
B) by increasing cost of components
C) by decreasing component commonality with their other offerings
D) by decreasing assembly time
7) If a company is capable of delivering the service over and over again in the volumes needed it is said to
have a high level of scalability.
8) The ease with which parts can be replaced, checked or evaluated is testability.
9) Robust design is the design of products to be less sensitive to manufacturing variation and misuse.
10) The operations function is more tightly coupled with new service designs than with new product
designs because the new service designs are often the operations process itself.
11) An airline specifies a wider monitor for installation on their overseas flights. The airframe
manufacturer will accommodate this order by issuing an engineering change.
12) Product design refers to the characteristics or features of a product or service that determine its ability
to meet the needs of the user.
13) All product development efforts directly benefit the consumer.
14) New products or services provide benefits to the firm.
16) ________ refers to the ease with which critical components or functions can be tested during
production.
17) The unexpected expenses associated with overhead and engineering change notices are ________.
18) What are robust design, testability, and serviceability and how are they related?
19) What are the four reasons that a company might develop new products and services?
20) Provide an example from industry of a product or service that was duplicated by a competitor. Was
this considered successful from the perspective of the first company? The competitor?
15.2 The Development Process
1) 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.
2) The feasibility of a product or service is evaluated during the:
A) planning phase.
B) evaluation phase.
C) launch phase.
D) concept development phase.
3) 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.
4) 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.
5) The concept development phase addresses the feasibility of a product or service.
6) In the planning phase, the operations and supply chain function develops initial cost estimates and
identifies key supply chain partners.
7) In the launch phase of product development it is typically the marketing department‘s responsibility to
fill the downstream supply chain.
8) The development funnel demonstrates that while initial conceptual development takes a long time,
product design can progress quickly through the final phases of development.
9) Products developed using a concurrent engineering process can be developed more quickly than those
using a sequential development process.
10) The company begins to address the feasibility of a product or service in the ________ phase of the
development process.
11) The ________ process occurs because 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?
15.3 Organizational Roles in Product and Service Development
1) The development of specifications for the manufacturing equipment needed to make the product is the
responsibility of what function?
A) engineering
B) marketing
C) accounting
D) purchasing
2) The process of preapproving suppliers for specific commodities or parts is known as:
A) screening.
B) presourcing.
C) presaging.
D) certifying.
3) In high tech firms, the group most likely to be taking the lead in being responsible for the success of a
product development process is:
A) scientists and engineers.
B) marketing.
C) consumers.
D) accounting/finance.
4) 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.

table with an automobile manufacturer through all phases of product development.
12) ABC Corporation knew that XYZ Industries could provide the casings needed for their new line of
