Title: Scope of Operations Management


1
Operations and Project Management
2
Operations in different industrial sectors
  • What operations are typical of
  • Primary? Secondary? Tertiary sectors?
  • What of UK GDP does each produce?
  • What has been the shift in P -S -T emphasis
    1970-2004 in UK exports/imports?
  • What of visible trade in 2002 was made up of
    manufactures?
  • Most services incl. elements of product viz.

3
What do Operations Managers do?
  • With your partner, choose "an operation" and list
    the main activities the operations manager must
    manage.
  • role demands
  • planning
  • decisions
  • coordination
  • systems

4
What is Operations Management?
  • Core management activity - operations deliver
  • Creating, operating controlling transformation
    systems
  • inputs (resources ideas) produce outputs (goods
    and services) for customers (external internal)
  • Managing processes methods
  • production, productivity, efficiency
  • resources staff (80) physical, technical
    systems
  • Design for production, delivery, information
    control, value- added, quality
  • Concerns design, supply, capacity, scheduling,
    quality

5
Operations as a system
Demanding environment
Transformation (Conversion) Process
Goods Services
Boundary management
Boundary management
Capital
Information
Feedback (information) - control over process
inputs technology
6
Process System (Operation), Variety Volume
  • One-off jobbing - specials, design,
    build,deliver. Low volume, low standardisation
  • Project Management - large, coordinated, special
    case
  • job shop small batch production, disconnected
    flow. Low volume, multiple but similar products
  • connected flow line
  • one product - high volume,high standardisation
  • large batch - high volume,high standardisation
    across
  • many product variants
  • Continuous flow - high volume,high
    standardisation
  • Services
  • role demands
  • decisions
  • information
  • coordination
  • flexibilities
  • supply chain
  • customer interface

7
Processes Characteristics Matrix
  • Market conditions, competition
  • Capital requirements
  • Labour supply cost
  • Management skills
  • Materials supply cost
  • State of technology

Ops Mgt - a complex interfacing role
  • thinkers doers decision-takers
  • many people to be managed 70 of assets
  • largest budget areas/cost centres
  • direct costs overheads, process and
    time-oriented
  • measurable/controllable measures of progress
    outputs (product, volume, time, , wastage,
    labour).
  • work-flow and cash-flow
  • short-termism (time constraints dependencies)
  • cost of a days lost production vs. long-term
    perspectives
  • hard-edged management of product process
    technology
  • information sub-systems to control the whole
  • logistics and dispersed operations

10
A Broad Field
  • market strategic implications
  • research, design development (product
    service)
  • tactical programmes (product-service mix, variety
    value)
  • capacity management scheduling
  • facilities layout
  • information control systems
  • process design engineering, work study
    productivity
  • materials planning stock control
  • work structuring, motivation rewards
  • equipment maintenance servicing
  • QA
  • health, safety environmental care

11
The Operations Environment
Competitive External Environment
The Economy, the Society
Staff skills
Marketing
Design Engineering
Ops transformation system
Suppliers
Customers
Finance Accounting
Purchasing Logistics
Information Systems
Government
12
Linking operations to business strategy
  • strategic alternatives
  • product imitator
  • product innovator

Marketing fits easily within corporate debate.
Corporate bosses seldom have operations
experience. Assume operations will cope. "We
sell products services NOT market segments"
  • How to
  • qualify for market entry and
  • become order winners in a market.
  • Focus on how products/services win orders
  • NOW and TOMORROW

13
Operations Strategy
  • Contribution to
  • competitiveness and market leadership
  • Operations functions
  • needs clear, consistent, achievable objectives
    implementation
  • A move from safe, conservative ops to
    market/fashion leader? requires different
    better
  • responsiveness,quality, information, control,
    skills
  • production processes, supplier relationships
  • uses of technology and design applications

Who what drives ops strategy technological
innovation? Accountants, marketing, sales,
partners, innovators and inventions,
competitors, customers?
14
Beyond the Engineering Ops Mgr.
  • Traditionally busy-busy male/macho.
  • hard - reactive, fire-fighters
  • local, technically focused thinkers (not
    corporate HQ types)
  • gut-feel, get the goods out
  • lower level focus on things gt concepts, now gt
    tomorrow, trade-offs gt creativity, coping gt
    long-term
  • Need to think strategically
  • informed, systematic development
  • intelligent, visionary implementation
  • researched decision-making detailed evaluation
    planning
  • balancing constraints
  • co-ordinate people/teams, technology IT systems

How does this fit in with services? Failures on
quality price?
15
Operations Strategy Model
16
Policy Areas
Policy Examples Strategic Choices
Process
In or out Automation Process flow Job
specialisation Supervision
Make or buy, automation, routinisation. FMS, JIT
Quality Systems
QMS approach, Training, suppliers
Inspection or zero defects, technical
Managerial skills, costs of quality
Facility size, Location, investment
One big or several small facilities Near markets,
low cost, or foreign Permanent or temporary
Capacity
High or low levels, centralised or
decentralised, tight controls? Warehousing
Stock logistics
Stock levels, Distribution, Control systems
17
From the early 1980s
  • Operations gets more attention
  • Not just manufacture (declining in terms of GDP)
    but services also.
  • Main influences
  • Competition Pacific Rim industrial machine
  • Privatisation, open markets de-regulation
  • Demand for higher quality goods - cheaper
    delivered quicker.
  • Market entry and order winners.
  • home firms losing market share must improve ops.
    practices
  • learn from Japanese experience
  • Are ops. managers sufficiently focused
  • To influence value added chain as a whole?
  • Make more contribution to strategic processes?

19
Value-Added Chain
  • Ops. Managers to address every activity on the
    chain. Performance related, value-added
    objectives include
  • right, first time. Produce to target quality.
  • time compression - customer response, lead times,
    eliminate delays, bottlenecks inventory
  • predictability - control events, actions
    relationships for flexibility (new
    products/service range, volume delivery)
  • control over costs (staff, facilities/technology,
    materials)
  • NB produce in-house or buy-in(out-source).

20
Analyse each value-added stage
  • identify elements/content (I-P-O info) of each
    stage design characteristics
  • how do we ( how well do we) secure supplies
    /suppliers other inputs?
  • how effectively do we
  • manufacture components from raw materials?
  • assemble components into finished goods
    services?
  • distribute finished product to wholesalers,
    retailers end-users?
  • provide maintenance after-care?

21
Peters Waterman - In Search of Excellence
  • Core business, stick to the knitting, lean
    organisation
  • Sept 1996 British Airways consider selling off BA
    Engineering, concentrate on transporting
    passengers cargo. Out-sourcing to save 1
    billion
  • baggage handling ticket processing
  • aircraft engineering maintenance
  • in-flight catering
  • computer services
  • Profitable market leader anticipating
  • deregulation of air travel
  • lower fares new competition
  • Ops Mgr. involvt in strategic decisions?
  • Can vertically integrated firm become too lean?
  • Undermining quality/flexibility by zealous
    out-sourcing?

22
Strategy reflected in
  • policies, plans/programmes, budgets allocations
  • systems, methods, actions, behaviours,
    communications
  • Key Facets
  • product devel. PLC innovators imitators
  • self-sufficiency (vertical integration) or
    out-sourcing
  • automation technological exploitation
  • adjusting the product-service mix
  • delivering quality, price availability
    (qualifiers vs. order winners)
  • process choice improvement
  • site/branch location
  • planning information systems (transaction
    MIS)
  • people competencies commitment (competitive
    advantage)

Contributions
  • Capacity capability
  • Can we produce? How well?
  • Efficiency
  • How well is the process managed controlled?
  • The transformation indicators ratios?
  • Cost/unit, cost/patient day, profit/employee,
    sales/employee?
  • Benchmark comparisons
  • efficiencies, processes outputs
  • investment - , technical human
  • quality, systems, RD

25
Market growth profitability
  • increased capacity long term investment
    (irreversible?)
  • have we the capacity to make/offer?
  • what will be the order rate/demand?
  • will customers queue, wait, take part-orders?
  • insufficient capacity (lose market share
    difficult to catch up)
  • excess capacity ---gt higher costs, low/negative
    ROI
  • inadequate capacity, long lead times, quality
    problems, competitors advantage
  • Do we lead or follow demand? At end of PLC
    market saturation, over-capacity, price
    competition.
  • Divest or diversify?

Design for manufacture (source T. Hill)
revised design
one-piece base elimination of fasteners
Modular design More variety from a set components
(modules) to be assembled. Reduce complexity
costs of product variations
31
MTS and MTO
  • Advantages/disadvantages
  • Key performance measures
  • Information flows

32
Make or Buy Decision
  • compare costs
  • quantitative qualitative decision
  • buy
  • Poor internal capacity/facilities?
  • Less complex acquisition, less internal
    scheduling mgt
  • Specialist, volume supplier, offers expertise
    lower prices
  • make
  • Cannot buy item/service at price, quality,
    quantity or delivery
  • Increase utilisation and capacity (plant
    people)
  • Reliability, risk - not being supplied to
    quality on time etc
  • Retain autonomy/independence
