must be exposed to modern approaches for
doing this effectively.

can be in direct supervision of operations
or in staff position in operations
management specialties such as supply
chain management and quality assurance.

How is operations relevant
to my major?
• Accounting
• Information

• Management
• “As an auditor you must
understand the fundamentals
of operations management.”
• “IT is a tool, and there’s no
better place to apply it than in
operations.”
• “We use so many things you
learn in an operations class—
scheduling, lean production,
theory of constraints, and
tons of quality tools.”
How is operations relevant
to my major?
• Economics
• Marketing
• Finance
• “It’s all about processes. I live
by flowcharts and Pareto
analysis.”
• “How can you do a good job
marketing a product if you’re
unsure of its quality or delivery
status?”
• “Most of our capital budgeting
requests are from operations,
and most of our cost savings,
too.”
OM Across the Organization
• Most businesses are supported by the
functions of operations, marketing, and
finance
• The major functional areas must interact to
achieve the organization goals
• Marketing is not fully capable of meeting
customer needs if they do not understand
what operations can produce
• Human resources must understand job
requirements and worker skills
OM Across the Organization
• Finance cannot judge the need for
capital investments if they do not
understand operations concepts and
needs.
• Information systems enables the
information
flow
throughout
the
organization.
• Accounting
needs
to
consider
inventory
management,
capacity
information, and labor standards.

Business Information Flow
Types of OM Decisions
• Part 1 : Strategic Choices: Operations
managers help to determine the company’s
global strategies and competitive priorities
and how best to design process that fit with
its competitive priorities.
• Part 2 : Process: Process are fundamental
to all activities that produce goods or
services. Operations managers make
process decisions about the types of work
to be done in house, the amount of
automation to use, and methods of
improving existing systems.
Types of OM Decisions
• Part 3 : Quality : Quality issues underlie all
process and work activity. Operations managers
help establish quality objectives and seek ways to
improve the quality of the firm’s products and
services.
• Part 4 : Capacity, Location, Layout: The types of
decisions in this category often require long-term
commitments. Operation managers help determine
the system’s capacity (Capacity); the location of
news facilities including global operations
(Location); and the organization of departments
and a facility’s physical layout (Layout)
Types of OM Decisions

Differences between
Manufacturing and Service
Organizations
• Services
• Intangible, perishable
product
• Service cannot be
inventoried
• High customer
contact
• Short response time
• Labor intensive
• Manufacturing
• Physical, durable
product
• Product can be
inventoried
• Low customer
contact
• Longer response
time
• Capital intensive
Differences between
Manufacturing and Service
Organizations

• Small Facilities
• Quality not easily

• Local Markets
• Large facilities
• Quality

• Regional, national
or
international

The Range From Services to
Products
Similarities between Services
and Manufacturing
• All use technology
• Both have quality, productivity, &
response issues
• All must forecast demand
• Each will have capacity, layout, and
location issues
• All
have
customers,
suppliers,
scheduling and staffing issues
Service - Manufacturing
• Manufacturing often provides services
• Services often provides tangible goods
• Some organizations are a blend of
service/
manufacturing/
quasimanufacturing (QM) organizations
• QM characteristics include
– Low customer contact & Capital Intensive
Trends in OM
Several business trends are currently
having a great impact on operations
management. These are
 Growth of the service sector
 Productivity Changes
 Global Competitiveness
 Quality, time and technological change
 Environmental, ethical and diversity
issues
Trends in OM
• Service sector growth: The service
sector of the economy is significant.
Services may be divided into three main
groups. These are
 Government
 Wholesale and retail sales
 Other
services
(transportation,
utilities, communication, health etc)
public
The share of the workforce in service
jobs is well above 60 percent in Britain,
Canada, France and Japan.
Trends in OM
• Service sector growing to
50-80% of non-farm jobsSee
Global
competitiveness
• Demands
for
higher
quality
• Huge
technology
changes
• Time based competition
• Work force diversity
Trends in OM
• Productivity Changes: Productivity is
the value of outputs (goods and
services) produced divided by the value
of input resources (wages, costs of
equipment and the like) used. The value
of output can be measured by what the
customer pays or simply by the number
of units produced or customers served.
The value of inputs can be measured by
their costs or simply by the number of
hours worked.
Trends in OM
• Global Competitiveness: Strong
global competition affects industries
everywhere. Most products today
are global composites of material
and services from throughout the
world. Polo Shirt is sewn in
Hondurus from cloth cut in the
United states.
Trends in OM
• Competition based on quality, time
and technology: Another important
trend is that more firms are competing
on the basis of time; filling orders
earlier
than
the
competitors,
introducing new products and services
quickly, and reaching the market first.
Another increasing important factor in
operations management is accelerating
technological change.
Trends in OM
• Ethical, workforce diversity and
environmental issues: Business face
more ethical quandaries than ever
before, intensified by an increasing
global
presence
and
global
technological change. Environment
issues, such as toxic wastes, poisoned
drinking water, poverty, air quality and
global warming are getting more
emphasis.
Today’s OM Environment
• Customers demand better quality, greater
speed, and lower costs
• Companies implementing lean systems
concepts – a total systems approach to
efficient operations
• Recognized need to better manage
information using ERP and CRM systems
• Increased
cross-functional
decision
making
Achieving Cross-Functional
Coordination
• A unified strategy should be
developed by management as a
starting point, giving each department
a vision of what it must do to help
fulfill the overall organizational
strategy.
• The organizational structure and
management hierarchy can be
redesigned
to promote crossfunctional coordination.
Achieving Cross-Functional
Coordination
• The goal-setting process and reward
systems
can
encourage
crossfunctional coordination.
• Improvements to information systems
also
can
boost
coordination.
Information must in part be tailored to
the needs of each functional manger.
Achieving Cross-Functional
Coordination
• Informal social systems are another
device that can be used to encourage
better understanding across functional
lines.
• Employee selection and promotion
also can help foster more crossfunctional coordination by encouraging
broad perspective and common goals.
Productivity
Productivity is a common measure on
how well resources are being used. In
the broadest sense, it can be defined as
the following ratio:
Outputs
Inputs
Factors Affecting
Productivity
Capital
Quality
Technology
Management
Measures of Productivity
• Partial measures
– output/(single input)
• Multi-factor measures
– output/(multiple inputs)
• Total measure
– output/(total inputs)
Total Measure Productivity
Total Measure Productivity = Outputs
Inputs
or
= Goods and services produced

policies in a week. They work 8 hours per
day, 5 days per week.
• A team of workers make 400 units, which
is valued by its standard cost of Tk.10
