CHAPTER 1
INTRODUCTION
LEARNING OBJECTIVES
 Describe and Explain concepts, functions and
nature of OM
 Identify current OM problems, issues and
trends.
 Describe and Explain approaches used by OM
What Is OM?

Production is the creation of goods and
services.
Operations management (OM) is the set of
activities that creates value in the form of
goods and services by transforming inputs
into outputs.
Operations management (OM) is the
management of systems or processes that
create goods and/or provide services.
Organizing to Produce
Goods and Services
Essential functions:
Marketing – generates demand
Production/operations – creates the product
Finance/accounting – tracks how well the
organization is doing, pays bills, collects the
money

WHY STUDY OM ?
one of three major functions (marketing,
finance, and operations) of any
organization.
we want (and need) to know how goods
and services are produced.
we want to understand what operations
managers do.
a costly part of an organization
WHAT OPERATIONS MANAGERS DO?
Planning
Organizing
Staffing
Leading
Controlling
Where are the OM Jobs?
Significant Events in OM
Current Trend in OM
Coordinate the relationships between
mutually supportive but separate
organizations.
Optimizing global supplier,
production, and distribution networks.
Increased co-production of goods and
services.
Current Issues in OM (cont’d)
Managing the customer’s experience
during the service encounter.
Raising the awareness of operations
as a significant competitive weapon.
New Trends in OM
Past
Causes
Future
Local or
national focus
Reliable worldwide
communication and
transportation networks
Global focus,
moving
production
offshore
Batch (large)
shipments
Short product life cycles and
cost of capital put pressure on
reducing inventory
Just-in-time
performance
Low-bid
purchasing
Supply chain competition
requires that suppliers be
engaged in a focus on the
end customer
Supply chain

Past
Causes
Future
Lengthy

development
Shorter life cycles, Internet,

communication, computeraided design, and
international collaboration
Rapid product

Job
specialization
Changing socioculture milieu;
increasingly a knowledge and
information society
Empowered
employees,
teams, and lean
production
New Trends in OM (cont’d)
Past
Causes
Future
Low-cost
focus
Environmental issues, ISO
14000, increasing disposal
costs
Environmentally
sensitive
production, green
manufacturing,
recycled materials,
remanufacturing
Ethics not
at forefront
Businesses operate more
openly; public and global
review of ethics; opposition
to child labor, bribery,
pollution
High ethical
standards and
social responsibility
expected
Productivity Challenge
Productivity is the ratio of outputs (goods
and services) divided by the inputs
(resources such as labour and capital)
The objective is to improve productivity!
 Note: Production is a measure of output only and not a measure of
efficiency
Productivity
Units produced
Productivity =
Input used
measure of process improvement.
represents output relative to input
Productivity Calculations
Labor productivity:
Productivity =
=
Units produced
Labor-hours used
1,000
250
= 4 units/labor-hour
Productivity Calculations (cont’d)
Multi-factors productivity:
Output
Productivity =
Labor + Material + Energy
+ Capital + Miscellaneous
Productivity Variables
Labor - contributes about 10% of the
annual increase.
Capital - contributes about 38% of the
annual increase
Management - contributes about 52% of
the annual increase
