more intellectual. A knowledge society implies that work is
more intellectual and therefore harder to measure. Because the
U.S. and many other countries are increasingly “knowledge”
societies, productivity is harder to measure. Using labor-hours as

CASE STUDY
UBER TECHNOLOGIES, INC.
1. The market has decided that Uber and its immediate competi-
tors are adding efficiency to our society. How is Uber providing
that efficiency?
First, some drivers (maybe most) may not require a wage that
equals those fully engaged in the “taxi” business. It truly could
be a supplemental income. . . . “I’m going that way anyhow
so let’s make a few dollars while on the way.” Similarly, the
capital investment cost approaches zero as the car is going that
direction anyhow. These are idle or underutilized resources.
From society’s perspective, Uber and its like competitors are
desirable because both idle or wasted labor and capital resources
are being utilized. At the same time, as a bonus, Uber is reduc-
ing traffic and auto pollution while speeding up the transport of
2. Do you think the Uber model will work in the trucking
industry?
Perhaps a business model similar to Uber’s can be applied to the
trucking industry. An estimated 30% of trucking backhauls are
3. In what other areas/industries might the Uber model be used?
Perhaps the Uber model can be used for package delivery, docu-
ments, and everything from flowers to groceries. Airbnb
VIDEO CASE STUDIES
FRITO-LAY: OPERATIONS MANAGEMENT
IN MANUFACTURING
This case provides a great opportunity for an instructor to stimulate
a class discussion early in the course about the pervasiveness of the
10 decisions of OM with this case alone or in conjunction with the
Hard Rock Cafe case. A 7-minute video filmed specifically for
this case is available from Pearson.
1. From your knowledge of production processes and from the
case and the video, identify how each of the 10 decisions of OM
is applied at Frito-Lay.
◼ Product design: Each of Frito-Lay’s 40-plus products
must be conceived, formulated (designed), tested (market
studies, focus groups, etc.), and evaluated for profitabil-
ity.
◼ Supply-chain management: Frito-Lay, like all other pro-
ducers of food products, must focus on developing and
auditing raw material from the farm to delivery.
◼ Inventory: Freshness and spoilage require constant effort
to drive down inventories.

2. How would you determine the productivity of the production
processes at Frito-Lay?

3. How are the 10 decisions of OM different when applied by the
operations manager of a production process such as Frito-Lay
than when applied by a service organization such as Hard Rock
Cafe?
HARD ROCK CAFE: OPERATIONS
MANAGEMENT IN SERVICES
There is a short video (7 minutes) available from Pearson and
filmed specifically for this text that supplements this case.
1. Hard Rock’s 10 decisions: This is early in the course to discuss
these in depth, but still a good time to get the students engaged in
the 10 OM decisions around which the text is structured.
◼ Process: The process can be discussed from many
perspectives: (a) the process of processing a guest, to
their seat, taking the order, order processing, delivery of
the meal, payment, etc., (b) the process of how a meal is
prepared (see, for instance, how one would make a Hard
Rock Hickory BBQ Bacon Cheeseburger (Figure 5.9) or
a Buffalo Chicken Mac & Cheese (Figure 14.9) or use
the Method Analysis tool discussed in Chapter 10, or (c)
some subset of any of these.
◼ Location: Hard Rock Cafes have traditionally been located
in tourist locations, but that is beginning to change.
◼ Layout: Little discussion in the case, but students may be
very aware that a kitchen layout is critical to efficient
food preparation and that a bar is critical in many food
◼ Scheduling: Because most Hard Rock Cafe’s sales are
driven by tourists, the fluctuations in seasonal, daily, and
hourly demands for food are huge. This creates a very
interesting and challenging task for the operations
served cold must be done. Bar equipment and point-of-
sale equipment must also work.

2. Productivity of kitchen staff is simply the output (number of
meals) over the input (hours worked). The calculation is how many
meals prepared over how many hours spent preparing them. The
3. Each of the 10 decisions discussed in Question 1 can be
addressed with a tangible product like an automobile.
◼ Product design: The car must be designed, tested, and costed
out. The talents may be those of an engineer or operations
manager rather than a chef, but the task is the same.
◼ Quality: At an auto plant, quality may take the form of
measuring tolerances or wear of bearings, but there is still
a quality issue.
◼ Process: With an auto, the process is more likely to be an
assembly-line process.
◼ Location: Hard Rock Cafe may want to locate at tourist
destinations, but an auto manufacturer may want to go to a
location that will yield low fixed or variable cost.
◼ Layout: An automobile assembly plant is going to be
