What is operations management (OM)?
 OM definition
 Responsibilities of Operations Managers
 Difference between OM and PM
What is operations management ?
1-The collection of people, technology, and systems within a company that has primary
responsibility for providing the organization’s products or services.
2-The management of the direct recourses that are required to produce and deliver an
organization's goods and services .
3- A discipline and profession that studies and practices the process of planning, designing,
and operating production systems and subsystems to achieve the goals of the
organization.
4- The business function responsible for planning, coordinating, and controlling the
resources needed to produce a company’s products and services.
5- The management of the conversion process that transforms inputs into outputs in the
form of finished goods and services.

The transformation process within OM
Input-transformation-output relationships for typical systems
What is operations management ?
 Operations management is the set of activities that create value in the form of
goods and services by transforming inputs into outputs
 Value added is the net increase between output product value and input material
value (The value of the outputs is greater than the value of the inputs, resulting in
the profit or the benefit for government or non-profit organizations)
 All types of organizations, manufacturing or service, large or small, transform
inputs into outputs.
 Every organization has OM function, since all organizations provide products or
services, but the function may be formal or informal (In many smaller
organizations operations management may be done by people who perform many
other types of task such as marketing and accounting)
What's the difference between PM
and OM?
• Some thinks that they are really one and the same by different names.
• others think that production management is just a subset of operations
management because operations involve
more than just production.
• if services concept added to the production
management it can be called operations
management.
What responsibilities do operations managers
have?
• Direct responsibilities :the activities which are
directly related to producing and delivering products
and services.
• Indirect responsibilities :the activities involved in
interfacing with other parts of the organization.
• Broad responsibilities :a wider set of tasks that
involve scanning the business, social and political
environment in which the organization exists in order
to understand its context.

Importance of OM
1- Operations is an important part of every organization
2- We should know how goods and services are produced (All managers should have an
understanding the main principles and tools of OM)
3- It is responsible for the customer fulfillment aspects of an organization. Thus, it
manages customer satisfaction.
4- OM is such a costly part of an organization. (For most organizations it absorbs a huge
percentage of required capital )
Companies need to have efficient operations to survive. To succeed, a firm must have a
strong operations function teaming with the other organization functions.
5- OM responsible to increase productivity and profitability. Increasing overall
productivity leads to economic growth and a higher standard of living.
6- Operational decision-making requires a long-term perspective and requires inputs
from all business functions.
OM Decisions tend to be costly and difficult to reverse
Strategic options managers use to gain
competitive advantage
• 28% - Operations Management (+quality?)
• 18% - Marketing/distribution
• 17% - Momentum/name recognition
• 16% - Quality/service
• 14% - Good management
• 4% - Financial resources
• 3% - Other
Some definitions
• Productivity: The ration of what is produced by an operation or process to what is
required to produced it, that is ,the output from the operations divided by the input to
the input operation (ratio of output to input)
• Efficiency: producing something at the lowest possible cost
• Effectiveness: doing the right things to create the most value for the firm
• Value: quality divided by price
• Competitive advantage: competitive advantage is an advantage over competitors
gained by offering consumers greater value, either by means of lower prices or by
providing greater benefits and service that justifies higher prices
3- OM decisions
Strategic
Tactical
operational
• Where should we locate our facility
• How much capacity do we need
• What should we make, what should we buy
• What technology should we use
• How do we insure appropriate quality
• Who should we use as vendors
• How much inventory do we need
• How should we schedule our resources
Main operational decisions
Critical decisions of OM
• Product & service design.
• Quality management.
• Process design.
• Capacity & location of facilities.
• Layout of facilities.
• Human resource & Job design.
• Supply-chain management.
• Inventory management.
• Scheduling.
• Maintenance.
OM decisions
Operations managers must make decisions on three levels:
Strategic decisions
• senior management responsibility
• More broad in nature
• Determine the success of an organization's strategy,
• Very risky and hard to reverse
• Have significant long - term impact, ,and
• less frequent.
• Examples:
• How will we make the product?
• Where do we locate the facility?
• How much capacity do we need?
• When should we add more capacity?
Tactical decisions
• Medium- range decisions focus on resource needs, schedules, &
quantities to produce
• Tactical decisions are frequent, must align with strategic decisions.
• Involves resource allocation and utilization.
• Involves a moderate degree of uncertainty and risk..
• They are the link between lower and high level management
• Examples:
• How many workers do we need?
• When do we need them?
• Should we work overtime or put on a second sift?
• When should we have material delivered?
• Should we have a finished goods inventory?
Operational decisions
• Involves a short time horizon.
• Involves very little uncertainty and risk.
• Examples :
• What jobs do we work on today or this week?
• To whom do we assign what task?
• What jobs have priority?

4- OM's contributions to society
Higher Standard of Living
Better Quality Goods and Services
Concern for the Environment
Improved Working Conditions
Operations management's
contributions to society
OM's contributions to society:-
(A)- Higher Standard of Living
(B) - Better Quality Goods and Services
(C)- Concern for the Environment
(D)- Improved Working Conditions
(A)- Higher standard of living
• A major factor in raising the standard of living in a society is the
ability to increase its productivity.
• Higher productivity is the result of increased efficiency in
operations, which in turn translates into lower cost goods and
services.
• Thus, higher productivity provides
consumers with more discretionary
income, which contributes to their
higher standard of living.
(B) - Better quality of goods and services
• One of the many consumer benefits of increased
competition is the higher-quality products that are
available today.
• Quality standards are continually increasing.
• Many companies today have established Six-Sigma quality
standards (pioneered by Motorola in the late 1980s),
resulting in no more than 3.4 defects per million
opportunities.
• Such high quality standards were once considered not
only prohibitively expensive but also virtually impossible
to achieve even if cost wasn't a consideration.
• Today we know that such high quality is not only very
possible, but also results in lower costs, because firms
can reduce their waste and rework.
1-Improve productivity
3- Lower cost of goods & services
5-Higher standard of living
Higher standard of living
2- Result of increased
efficiency in operations
4- More income
(C)- Concern for the
environment
Many companies today are taking up the
challenge to produce environmentally
friendly products with environmentally
friendly processes, all of which falls
under the purview of operations
management.
• Recycling and concern for air and water
quality
(D)-Improved working
conditions
• Managers recognize the benefits of providing workers with better
working conditions.
• This includes not only the work environment but also the design of the
jobs themselves.
• Workers are now encouraged to participate in improving
operations through suggestions.
• After all, who would know better how to do a particular operation
than that person who does it every day.
• Managers also have learned that there is a very clear relationship
between satisfied workers and satisfied customers, especially in
service operations.
• (Empowerment :The concept of encouraging and authorizing
workers to take the initiative to improve operations, reduce
costs, and improve product quality and customer service.)
5- OM of service and manufacturing organizations
Importance of service now
Service nature
The affect of service nature on OM activities
OM of service and manufacturing
organizations
• Initially, operations management concepts focused almost entirely
on manufacturing.
• As countries become more developed, services continue to represent a larger
percentage of their economies.
• Now Less than 20%of all jobs are in manufacturing (and they are
declining)
• Almost 80% of jobs are in the service sector (and they are
increasing)
• Nearly half of all jobs are in POM

Manufacturing vs. service
1- Customer contact:
Service, by nature, involves a much high degree of customer contact than manufacturing.
The performance of service often occurs at the point of consumption. Manufacturing allows
a separation between production and consumption, so that manufacturing can occur away
from the consumer.
Customer are sometimes apart of the system (self-service operations-shopping +gas stations)
so tight control on process is impossible
2- Uniformity of input:
• Service operations are subject to greater variability of input than typical manufacturing
operations.
• Each patient, each client and each auto repair presents a specific problem that
often must be diagnosed before it can be remedied
• Manufacturing operations often have the ability to carefully control the amount of
variability of input and thus achieve low variability in outputs.
• Job requirements for manufacturing are generally more uniform than those for service
Manufacturing vs. service
3- Labor content of jobs:
Many services involve a higher labor content than manufacturing operations
4- Uniformity of output
Because high mechanization generates products with low variability ,
manufacturing tends to be smooth and efficient ,
service activities sometimes appear to be slow and awkward and output is
more variable. Automated services are exception to this
5- Measurement of productivity
Measurement of productivity is more straightforward in manufacturing
due to the high degree of uniformity of most manufacturing items.
In service operations , variations in demand intensity and in requirements from
job to job make productivity measurement more difficult
•Attributes of GOODS
Tangible product
- Product can be inventoried.
- Some aspect of quality are measurable.
- Selling is distinct from production.
- Site of facility is important for cost.
- Often easy to automate.
- Revenue is generated primarily from
the tangible product.
Capital intensive
Goods vs. services
•Attributes of SERVICES
• Intangible Products
- Many services cannot be inventoried.
- Many aspects of quality are difficult to measure.
- Selling is often a part of the service.
Provider, not product, is often transportable.
Site of facility is important for customer contact.
Service is often difficult to automate.
Revenue is generated primarily from the intangible
service.

6- The ever - changing world of OM
Increased global competition
Advances in technology
Linking OM to customers and suppliers
The ever-changing world
of OM
• Operations management is continuously
changing to meet the new and exciting
challenges of today's business world.
• This ever-changing world is characterized by
increasing global competition and advances in
technology. Emphasis is also shifting within the
operations function to link it more closely with
both customers and suppliers.
• Here we will consider these issues:
(A)- Increased global
competition
• Global (economy, village, and landscape): are terms used to describe how the
world is becoming smaller, and countries are becoming
more dependent on each other.
• The world is rapidly transforming itself into a single global economy, which
referred to as a global village or global landscape.
• Markets once dominated by local or national companies are now vulnerable
to competition from literally all corners of the world. For example, in the
1960s, only 7 percent of the firms in the United States exposed to foreign
competition; by the late 1980s,
• This figure exceeded 70 percent, and that percentage has continued to
grow.
• Consequently, as companies expand their business to include foreign
markets, so too must the operations management function take a more
global perspective in order for companies to remain
competitive.
• To s prosper in such a global marketplace companies must excel in
more than one dimension, which previously was the norm.

Manufacturing of the Escort
(B)- Advances in technology
• Advance in technology in recent years have had a
significant effect on the OM function:
• IT+ automation + Internet
• Competition
• Product life cycle
• New jobs
• Robots
• E-???
(C )- Linking OM to customers
and suppliers
• In the past, most manufacturing organizations viewed operations
strictly as an internal function that had to be buffered from
the external environment by other organizational functions.
• Orders were generated by the marketing function; supplies and raw
materials were obtained through the purchasing function; capital for
equipment purchases came from the finance function; the labor
force was obtained through the human resources function; and the
product was delivered by the distribution function
• Now more and more firms are recognizing the competitive
advantage achieved when the transformation process is not
isolated, as when customers are invited to view their
operating facilities firsthand
(C )- Linking OM to customers
and suppliers
companies are working more closely with suppliers.
• Firms like Toyota, have suppliers deliver product directly to the
factory floor, eliminating need for a stockroom.
• The relationship between the transformation processes of suppliers and
customer often referred to as a product's value chain.
• ( steps an organization requires to produce a good or service, regardless of where
the are performed)
• A value chain consists of all the steps actually add value to the
product. This concept helps managers to eliminate all non added steps
(such as inspections and inventory) and consequently results in a
higher of dependence among the value-added functions within the chain.
• This integration of both suppliers and customers into the transformation
process to blur the boundaries between what were previously totally
independent organizations (Virtual enterprises)
• (company whose boundaries are not clearly defined due to the integration of
customers and suppliers)
7- Make or buy?
Capacity
Expertise
Quality
Demand
Cost
Risk
Make or buy?
• Many organizations buy parts or contract out services, for a
variety of reasons. Among those factors are:
1- Available capacity:
• If an organization has available the equipment, necessary
skills, and time, it often make sense to produce an item or
perform a service in-house.
• The additional costs would be relatively small compared with
required to buy items or subcontract services.
2- Expertise:
• If a firm lacks the expertise to do a job satisfactorily, buying
might be a reasonable alternative.
Make or buy?
3- Quality consideration:
Firms that specialize can usually offer high quality than an organization
can attain itself.
Conversely, unique quality requirements or the desire to closely monitor quality
may cause an organization to perform a job itself.
4- The nature of demand:
When demand for an item is high and steady, the organization is often better
off doing the work itself.
However, wide fluctuations in demand or small orders are usually better
handled by specializations who are able to combine orders from multiple
sources, which results in a higher volume and tends to offset individual
buyer fluctuations.
Make or buy?
5- Cost:
Any cost savings achieved from buying or making must be weighted against the preceding
factors.
Cost saving might come from the item itself or from transportation cost savings.
If there are fixed costs associated with making an item that cannot be reallocated if the service or
product is outsourced , that has to be recognized in the analysis.
Conversely, outsourcing may help a firm avoid incurring fixed costs.
6- Risk:
Outsourcing may involve certain risks. one is loss of control operations. Another is the
need to disclose propriety information.
In some cases , a firm might choose to perform part of the job itself and let
others handle the rest in order to maintain flexibility and to hedge against
loss of a subcontractor .
If part or all the work will be done “ in-house”, capacity alternatives will need to
developed

Prior to 1900
Scientific Management
Other Management Pioneers (Gilbreth + Gantt)
Moving Assembly Line
Hawthorne Studies
Operations Research
OM Emerges as a Field
The Marriage of OM and IT
OM in Services
Integration of Manufacturing and Services
Historical development of OM
Prior to 1900:
• Cottage industry produced custom-made goods.
• Watt’s steam engine in 1785.
• Whitney’s standardized gun parts in 1801.
• Industrial Revolution began at mid-century.
Scientific Management (Frederick W. Taylor):
• Systematic approach to increasing worker productivity through time study,
standardization of work, and incentives.
• Viewed workers as an interchangeable asset.
Other Management Pioneers:
• Frank and Lillian Gilbreth
• Motion study and industrial psychology
• Henry L. Gantt
• Scheduling and the Gantt chart
Historical development of OM
Moving Assembly Line (1913):
• Labor specialization reduced assembly time.
Hawthorne Studies:
• Yielded unexpected results in the productivity of Western Electric plant
workers after changes in their production environment.
• Led to recognition of the importance of work design and employee
motivation.
Operations Research (Management Science):
• Outgrowth of WWII needs for logistics control and weapons-systems
design.
• Seeks to obtain mathematically optimal (quantitative) solutions to complex
problems.
OM Emerges as a Field:
• 1950–1960, OM moved beyond industrial engineering and operations
research to the view of the production operation as a system.
• 1950–1960, OM moved beyond industrial engineering and operations
research to the view of the production operation as a system
Historical development of OM
The Marriage of OM and IT:
• Integrated solutions approaches
• Business process reengineering
• Supply chain management
• Systems integration (SAP)
Operations Management in Services:
• OM concepts can apply to both manufacturing and service
operations.
Integration of Manufacturing and Services:
• Conducting world class operations requires compatible
manufacturing and service operations
Last word
• Shifts from cost and efficiency to value, from mass production to lean
production, from manufacturing technology to information technology, and from
national economy to world economy have made OM critically important
in modern business.
• Workers are different; they demand increasing levels of empowerment and more
meaningful work.
• Customers are different, their demands and expectations are much higher.
• Technology is different; computers & automation have dramatically changed the
nature of work, requiring constant learning and more abstract thinking.
• Finally the environment is different, we live in a global business environment
without boundaries .
• Such changes in business are occurring at an increasingly rapid pace, and we can
expect them to continue in the future. Operations managers clearly face
important challenges in preparing for this century.
Last word?
• “Paying attention to customers and knowing what they
want is a fundamental and important beginning.
• However, given that several competing companies pay
attention to what customers want, the key to
competitiveness then becomes production capability.
What differentiates winners from losers is that winners
are better able to consistently provide products and
services that are competitive with regard to
quality, price, time and agility

    Manufacturing vs. service 1-Customer contact: Service, by nature, involves a much high degree of customer contact than manufacturing. The performance of service often occurs at the point of consumption. Manufacturing allows a separation between production and consumption, so that manufacturing can occur away from the consumer. Customer are sometimes apart of the system (self-service operations-shopping +gas stations) so tight control on process is impossible 2- Uniformity of input: • Service operations are subject to greater variability of input than typical manufacturing operations. • Each patient, each client and each auto repair presents a specific problem that often must be diagnosed before it can be remedied • Manufacturing operations often have the ability to carefully control the amount of variability of input and thus achieve low variability in outputs. • Job requirements for manufacturing are generally more uniform than those for service
  • 44.
    Manufacturing vs. service 3-Labor content of jobs: Many services involve a higher labor content than manufacturing operations 4- Uniformity of output Because high mechanization generates products with low variability , manufacturing tends to be smooth and efficient , service activities sometimes appear to be slow and awkward and output is more variable. Automated services are exception to this 5- Measurement of productivity Measurement of productivity is more straightforward in manufacturing due to the high degree of uniformity of most manufacturing items. In service operations , variations in demand intensity and in requirements from job to job make productivity measurement more difficult

    6- The ever- changing world of OM Increased global competition Advances in technology Linking OM to customers and suppliers

    The ever-changing world ofOM • Operations management is continuously changing to meet the new and exciting challenges of today's business world. • This ever-changing world is characterized by increasing global competition and advances in technology. Emphasis is also shifting within the operations function to link it more closely with both customers and suppliers. • Here we will consider these issues:
  • 48.
    (A)- Increased global competition •Global (economy, village, and landscape): are terms used to describe how the world is becoming smaller, and countries are becoming more dependent on each other. • The world is rapidly transforming itself into a single global economy, which referred to as a global village or global landscape. • Markets once dominated by local or national companies are now vulnerable to competition from literally all corners of the world. For example, in the 1960s, only 7 percent of the firms in the United States exposed to foreign competition; by the late 1980s, • This figure exceeded 70 percent, and that percentage has continued to grow. • Consequently, as companies expand their business to include foreign markets, so too must the operations management function take a more global perspective in order for companies to remain competitive. • To s prosper in such a global marketplace companies must excel in more than one dimension, which previously was the norm.

    (B)- Advances intechnology • Advance in technology in recent years have had a significant effect on the OM function: • IT+ automation + Internet • Competition • Product life cycle • New jobs • Robots • E-???
  • 51.
    (C )- LinkingOM to customers and suppliers • In the past, most manufacturing organizations viewed operations strictly as an internal function that had to be buffered from the external environment by other organizational functions. • Orders were generated by the marketing function; supplies and raw materials were obtained through the purchasing function; capital for equipment purchases came from the finance function; the labor force was obtained through the human resources function; and the product was delivered by the distribution function • Now more and more firms are recognizing the competitive advantage achieved when the transformation process is not isolated, as when customers are invited to view their operating facilities firsthand
  • 52.
    (C )- LinkingOM to customers and suppliers companies are working more closely with suppliers. • Firms like Toyota, have suppliers deliver product directly to the factory floor, eliminating need for a stockroom. • The relationship between the transformation processes of suppliers and customer often referred to as a product's value chain. • ( steps an organization requires to produce a good or service, regardless of where the are performed) • A value chain consists of all the steps actually add value to the product. This concept helps managers to eliminate all non added steps (such as inspections and inventory) and consequently results in a higher of dependence among the value-added functions within the chain. • This integration of both suppliers and customers into the transformation process to blur the boundaries between what were previously totally independent organizations (Virtual enterprises) • (company whose boundaries are not clearly defined due to the integration of customers and suppliers)

    7- Make orbuy? Capacity Expertise Quality Demand Cost Risk
  • 54.
    Make or buy? •Many organizations buy parts or contract out services, for a variety of reasons. Among those factors are: 1- Available capacity: • If an organization has available the equipment, necessary skills, and time, it often make sense to produce an item or perform a service in-house. • The additional costs would be relatively small compared with required to buy items or subcontract services. 2- Expertise: • If a firm lacks the expertise to do a job satisfactorily, buying might be a reasonable alternative.
  • 55.
    Make or buy? 3-Quality consideration: Firms that specialize can usually offer high quality than an organization can attain itself. Conversely, unique quality requirements or the desire to closely monitor quality may cause an organization to perform a job itself. 4- The nature of demand: When demand for an item is high and steady, the organization is often better off doing the work itself. However, wide fluctuations in demand or small orders are usually better handled by specializations who are able to combine orders from multiple sources, which results in a higher volume and tends to offset individual buyer fluctuations.
  • 56.
    Make or buy? 5-Cost: Any cost savings achieved from buying or making must be weighted against the preceding factors. Cost saving might come from the item itself or from transportation cost savings. If there are fixed costs associated with making an item that cannot be reallocated if the service or product is outsourced , that has to be recognized in the analysis. Conversely, outsourcing may help a firm avoid incurring fixed costs. 6- Risk: Outsourcing may involve certain risks. one is loss of control operations. Another is the need to disclose propriety information. In some cases , a firm might choose to perform part of the job itself and let others handle the rest in order to maintain flexibility and to hedge against loss of a subcontractor . If part or all the work will be done “ in-house”, capacity alternatives will need to developed

    Historical development ofOM Prior to 1900: • Cottage industry produced custom-made goods. • Watt’s steam engine in 1785. • Whitney’s standardized gun parts in 1801. • Industrial Revolution began at mid-century. Scientific Management (Frederick W. Taylor): • Systematic approach to increasing worker productivity through time study, standardization of work, and incentives. • Viewed workers as an interchangeable asset. Other Management Pioneers: • Frank and Lillian Gilbreth • Motion study and industrial psychology • Henry L. Gantt • Scheduling and the Gantt chart
  • 59.
    Historical development ofOM Moving Assembly Line (1913): • Labor specialization reduced assembly time. Hawthorne Studies: • Yielded unexpected results in the productivity of Western Electric plant workers after changes in their production environment. • Led to recognition of the importance of work design and employee motivation. Operations Research (Management Science): • Outgrowth of WWII needs for logistics control and weapons-systems design. • Seeks to obtain mathematically optimal (quantitative) solutions to complex problems. OM Emerges as a Field: • 1950–1960, OM moved beyond industrial engineering and operations research to the view of the production operation as a system. • 1950–1960, OM moved beyond industrial engineering and operations research to the view of the production operation as a system

    Historical development ofOM The Marriage of OM and IT: • Integrated solutions approaches • Business process reengineering • Supply chain management • Systems integration (SAP) Operations Management in Services: • OM concepts can apply to both manufacturing and service operations. Integration of Manufacturing and Services: • Conducting world class operations requires compatible manufacturing and service operations

    Last word • Shiftsfrom cost and efficiency to value, from mass production to lean production, from manufacturing technology to information technology, and from national economy to world economy have made OM critically important in modern business. • Workers are different; they demand increasing levels of empowerment and more meaningful work. • Customers are different, their demands and expectations are much higher. • Technology is different; computers & automation have dramatically changed the nature of work, requiring constant learning and more abstract thinking. • Finally the environment is different, we live in a global business environment without boundaries . • Such changes in business are occurring at an increasingly rapid pace, and we can expect them to continue in the future. Operations managers clearly face important challenges in preparing for this century.
  • 62.
    Last word? • “Payingattention to customers and knowing what they want is a fundamental and important beginning. • However, given that several competing companies pay attention to what customers want, the key to competitiveness then becomes production capability. What differentiates winners from losers is that winners are better able to consistently provide products and services that are competitive with regard to quality, price, time and agility
