In a concurrent engineering approach to product design and development, an integration
team ensures that various parts of the product are compatible with the needs of the
target customer.
Economies of scope exist when multiple products can be produced at a lower cost in
combination than they can separately.

design

You are using an exponential smoothing model for forecasting. The running sum of the
forecast error statistics (RSFE) are calculated each time a forecast is generated. You
find the last RSFE to be 34. Originally, the forecasting model used was selected because
of its relatively low MAD of 0.4. To determine when it is time to re-evaluate the
usefulness of the exponential smoothing model, you compute tracking signals. Which
of the following is the resulting tracking signal?
A. 85
B. 60
C. 13.6
D. 12.9
E. 8
Which of the following is a cost impact and payoff analysis tool from the operations

Which company is mentioned in the text as a pioneering of the production line
approach to delivering on-site service?
A. Ritz-Carlton Hotel Company
B. McDonald’s Corporation
C. Prudential Insurance Company
D. Southwest Airlines
E. Citibank
Which of the following is not a suggestion for managing queues presented in the
textbook?

In the service-system design matrix, a face-to-face total customization service
encounter is expected to have which of the following?
A. Low sales opportunity
B. Low production efficiency
C. High production efficiency
D. Low degree of customer/server contact
E. None of these
Which of the following are the three major components of a queuing system?
A. The source population, how customers exit the system, and the queuing discipline
B. The number of servers, the service speed, and the waiting line
C. The source population, how the customer exits the system, and the servicing system
D. The source population and the way customers arrive at the system, the serving
systems, and how customers exit the system
E. The service speed, the queue discipline, and the waiting line

A work center has five jobs assigned to it. They are labeled, in the order of their arrival
in the shop, as jobs A, B, C, D, and E. The work center may work on only one job at a
time and must complete any job it starts before starting another job. Job A has a
processing time of 6 days and is due to the customer in 9 days. Job B has a processing
time of 2 days and is due in 16 days. Job C has a processing time of 4 days and is due in
10 days. Job D has a processing time of 3 days and is due in 7 days. Job E has a
processing time of 5 days and is due in 12 days. Using the earliest due date (EDD)
priority rule, what will be the average lateness of these orders?

As a consultant, you have been asked to generate a unit demand forecast for a product
for year 2014 using exponential smoothing. Actual demand in year 2013 was 950, but
the forecast for that year was 1,060. Using these data and a smoothing constant alpha of
0.5, what is the resulting year 2014 forecast value?
