Who are our good suppliers and how many should we have?
Inventory, material requirements planning,
How much inventory of each item should we have?

CHANGING CHALLENGES FOR THE OPERATIONS
MANAGER
Past
Causes
Future
Local or
national
focus
Batch (large)
shipments
Low-bid
purchasing
Lengthy
product
development
Low-cost, reliable worldwide
communication and
transportation networks
Cost of capital puts pressure on
reducing investment in
inventory
Quality emphasis requires that
suppliers be engaged in product
improvement
Shorter life cycles, rapid
international communication,
computer-aided design, and
international collaboration
Global Focus
Just-in-time
shipments
SC partners, ERP
Rapid product
development,
alliances,
collaborative
designs

CHARACTERISTICS OF GOODS
Tangible product
Production usually
separate from
consumption
Consistent product
definition
Low customer interaction
Can be inventoried
17
CHARACTERISTICS OF SERVICE
Intangible product (Intangibility)
Produced & consumed at same
time (simultaneity)
Inconsistent product definition
(Heterogeneity)
High customer interaction
Often unique
Often knowledge-based
Frequently dispersed
18
GOODS CONTAIN SERVICES / SERVICES CONTAIN GOODS
Automobile
Computer
Installed Carpeting
Fast-food Meal
Restaurant Meal

THE SERVICE PACKAGE
Supporting Facility: The physical resources that must be
in place before a service can be sold. Examples are
golf course, hospital, hotel.
Facilitating Goods: The material consumed by the buyer
or items provided by the consumer. Examples are food
items, legal documents, golf clubs, medical history.
Information: Operations data or information to enable
efficient and customized service. Examples are patient
medical records, seats available on a flight, customer
preferences, location of customer to dispatch a taxi.
THE SERVICE PACKAGE (CONT.)
Explicit Services: Benefits readily observable by the
senses. The essential or intrinsic features. Examples are
absence of illness after treatment, smoothly running
vehicle after tune up, on-time departure.
Implicit Services: Psychological benefits or extrinsic
features which the consumer may sense only vaguely.
Examples are privacy of loan office, security of a well
lighted parking lot, staff courtesy.
PRODUCTIVITY
Measure of process improvement
Represents ratio of output to input
Productivity
Units produced
= Input used
Only through productivity increases can our
standard of living improve
23
MULTI-FACTOR PRODUCTIVITY
Productivity
=
Output
Labor + material + capital + energy + Misc
24
MEASUREMENT PROBLEMS
Quality may change while the quantity of inputs and
outputs remains constant
External elements may cause an increase or decrease in
productivity
Precise units of measure may be lacking
25
SERVICE PRODUCTIVITY
Reasons for low productivity in services
Frequently
Often
individually processed
an intellectual task performed by professionals
hence often difficult to mechanize
Growth
of low productivity activities e.g. food
preparation, laundry, house cleaning
26
TACO BELL - IMPROVING SERVICE PRODUCTIVITY
Revision
of menu to include meals that are easy to
prepare
Substantial
portion of food preparation shifted to
suppliers e.g. pre-cooking, predicing, etc
Efficient
design of layout and automation of
operations
Training
and empowerment of management to
increase competence – reduce labor
