6
What Is Operations Management?
  • Production is the creation of goods and services
  • Operations management is the set of activities
    that creates goods and services by transforming
    inputs into outputs

7
Significant Events I
The origins of Operations Management can be
traced back to the Industrial Revolution (in the
late 18th and early 19th centuries )
  • Division of labor (Smith, 1776)
  • Standardized parts (Whitney, 1800)
  • Scientific management (Taylor, 1881)

Ada Smith treats the topic of the division of
labor
Eli Whitney introduced concept of standard
interchangeable parts in 1799
He described how the application of the
scientific method to the management of workers
greatly could improve productivity
8
Significant Events II
  • Coordinated assembly line (Ford 1913)
  • Gantt charts (Gantt, 1916)
  • Motion study (the Gilbreths, 1922)
  • Quality control (Shewhart, 1924)

Manufacturing process in which interchangeable
parts are added to a product in a sequential
manner to create a finished product faster than
with handcrafting-type methods
Gantt designed his charts so that foremen or
other supervisors could quickly know whether
production was on schedule, ahead of schedule or
behind schedule
From their various studies the Gilbreths
developed, the laws of human motion from which
evolved the principles of motion economy
Father of statistical quality control
9
Significant Events III
  • CPM / PERT (Dupont, 1957)
  • MRP (Orlicky, 1960)
  • CAD
  • Flexible manufacturing systems (FMS)
  • Manufacturing automation protocol (MAP)
  • Computer integrated manufacturing (CIM)

CPM Critical Path Method, is used to determine
what is the shortest time to carry out the
project PERT Program (or Project) Evaluation and
Review Technique, is a technique developed in the
mid-50, used to program and control programmes to
be carried out
Material Requirements Planning (MRP) is a
software based production planning and inventory
control system used to manage manufacturing
processes.
10
Why Study OM?
  • OM is 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 know what operations managers do
  • OM is such a costly part of an organization

11
Why do I need OM in the future?
  • Many graduates are expected to rise to senior
    management levels
  • OM is the central core function of every company
  • Regardless of whether your area of expertise is,
    the techniques and concepts of OM will help you
    in your business career
  • Knowledge of OM will allow your future company to
    offer products and services cheaper, better, and
    faster.

12
What Operations Managers Do?
  • Plan planning the schedule according to sales
    demand (defining priorities)
  • Organize ensuring effective production of goods
    and services
  • Staff motivating and monitoring
  • Lead developing and cascading the organizations
    strategy
  • Control creating and maintaining a positive flow
    of work

13
Ten Critical Decisions
  • Service, product design
  • Quality management
  • Process, capacity design
  • Location
  • Layout design
  • Human resources, job design.
  • Supply-chain management
  • Inventory management
  • Scheduling
  • Maintenance

14
Organizational Functions
  • Marketing
  • Gets customers. It includes advertising,
    distribution and selling
  • Operations
  • Creates product or service
  • Is is the activity you carry out
  • Finance/Accounting
  • Obtains funds funds for business
  • Tracks money

15
Where are the OM Jobs?
  • As we said, OM is the central core function
    of every company, so there are a great variety of
    jobs in this field
  • Technology/methods
  • Facilities/space utilization
  • Strategic issues
  • Response time
  • People/team development
  • Customer service
  • Quality
  • Cost reduction
  • Inventory reduction
  • Productivity improvement

16
New Challenges in OM
Before
After
  • Local or national focus
  • Batch shipments
  • Low bid purchasing
  • Lengthy product development
  • Standard products
  • Job specialization
  • Global focus
  • Just-in-time
  • Supply chain partnering
  • Rapid product development, alliances
  • Mass customization
  • Empowered employees, teams

17
Characteristics of Goods
  • Tangible product
  • Consistent product definition
  • Production usually separate from consumption
  • Can be inventoried thereby giving system
    designers additional degrees of freedom
  • Low customer interaction

18
Characteristics of Goods
19
Characteristics of Service
  • Intangible product. No physical form
  • Produced consumed at same time
  • Often unique
  • High customer interaction
  • Inconsistent product definition
  • Often knowledge-based. Labor intensive
    (well-trained humans)
  • Frequently dispersed

20
Characteristics of Service
  • Service transactions are repetitive. Service
    needs are continuous.
  • The arrival rate of service request is random.
  • Nature of service demand is heterogeneous.
    Customers have unique needs.
  • Cannot be inventoried. Cannot be stored.
  • Service quality is difficult to assess.
    Subjective.

21
Characteristics of Service
  • A service is defined as a transaction in which
    the customer largely perceives the dominant
    value-adding component as being the intangible
    part of the product bundle.
  • Each total product experience has a tangible
    component but their dominant component is
    intangible.

22
Examples of Services
  • Tourist Office Officers advice
    Flying tickets

23
Goods Versus Services
Goods
Service
  • Reselling unusual
  • Difficult to inventory
  • Quality difficult to measure
  • Selling is part of service
  • Can be resold
  • Can be inventoried
  • Some aspects of quality measurable
  • Selling is distinct from production

24
Goods Versus Services - Continued
Goods
Service
  • Product is transportable
  • Site of facility important for cost
  • Often easy to automate
  • Revenue generated primarily from tangible product
  • Provider, not product is transportable
  • Site of facility important for customer contact
  • Often difficult to automate
  • Revenue generated primarily from intangible
    service.

25
Development of the Service Economy
Increasing exports employment in services sector
26
The Economic System Transforms Inputs to Outputs
27
Productivity
  • Measure of process improvement
  • Represents output relative to input
  • Productivity increases improve standard of living
    and creates income.
  • From 1889 to 1973, U.S. productivity increased at
    a 2.5 annual rate

28
Factors affecting Productivity
  • Capital investments in production/technology/equip
    ment/ facilities.
  • e.g. Automatization Computerization
    (minimizes tasks performed by employees).
  • Workforce knowledge and skill
  • Social environment. Making employees comfortable
    work methods.
  • Quality of products/processes/management
  • Geographic factors

29
Measurement Problems
  • Quality may change while the quantity of inputs
    and outputs remains constant. And will affect
    productivity.
  • External elements may cause an increase or
    decrease in productivity
  • Precise units of measure may be lacking. It can
    only be measured indirectly, that is, by
    measuring other variables and then calculating
    productivity from them.

30
Productivity Variables
  • Labor - contributes about 10 of the annual
    increase.
  • Capital - contributes about 32 of the annual
    increase
  • Management - contributes about 52 of the annual
    increase

31
Jobs in the U.S
32
Productivity Growth 1971- 1992
33
Service Productivity
  • Typically labor intensive
  • Frequently individually processed
  • Often an intellectual task performed by
    professionals
  • Often difficult to mechanize
  • Often difficult to evaluate for quality
