- Finance (Disbursements, Credits, Receivables, Payables, General Ledger, Funds Management, Money Market, International Exchange, Capital Requirements, Stock Issue, Bond Issue)
- Marketing (Sales promotion, Advertising, Sales, Market Research)
What is Operations Management?
- Production is the creation of goods and services.
- Operations Management (OM) is a set of activities that generate value by transforming inputs into outputs.
Why Study OM?
- OM is one of the three major functions (alongside marketing and finance) in any organization.
- Understanding how goods and services are produced is crucial.
- Operations managers play a key role in the organization.
- OM is a significant cost component for organizations.

- Ethics
Characteristics of Goods
- Tangible
- Production usually separate from consumption
- Can be inventoried
- Low customer interaction
Characteristics of Services
- Intangible
- Produced and consumed simultaneously
- Often unique
- High customer interaction
- Often knowledge-based
Goods Versus Services
- Attributes of Goods (Tangible) : Resellability, Inventory, Measurable Quality, Production distinct from selling, Transportability, Key is facility location, Automation potential, Revenue from tangible goods
- Attributes of Services (intangible) : Reselling is unusual, Difficult to inventory, Quality is difficult to measure, selling is part of service, Provider vs Product, Key is facility location and customer contact, Difficult to automate, Revenue from intangible products

- Consistency (Professionalism, Task Changes)
History of Operations Management
- Major Thrust of the Industrial Revolution (1850 - 1890)
- Industrial Revolution Details (factories small, total control by boss, little regard for workers)
- Production Manager Position (1890 - 1920)
- Scientific Management (Frederick Taylor)
- Complexity Increases (inventory, purchasing, scheduling, quality control)
Global Competition
- Global competition is intense.
- Factors favor certain countries or industries, such as Germany for printing & chemicals, Switzerland for pharmaceuticals & chocolate, Sweden for heavy trucks, US for computers etc., Japan for automobiles & consumer electronics.
Competitive Advantage
- A company has a competitive advantage when its profit rate exceeds the industry average.
- A sustained competitive advantage is maintained over several years.
Porter's Thesis
- Competitive advantage determinants (Factor conditions, Demand conditions, Related & supporting industries, Firm strategy, structure, and rivalry).
- Illustrative examples (e.g., German technological prowess, Japanese management style).
How Firms Differentiate
- Low-Cost Leaders (e.g., Korean automakers, some computer manufacturers)
- High-Quality Leaders (e.g., Mercedes Benz, Rolex)
Nature of Differentiation
- Tangible Differentiation (Observable characteristics: size, color, materials, etc.)
- Intangible Differentiation (Unobservable or subjective characteristics: image, status, identity)
Factors Driving Differentiation
- Unique product features
- Unique product performance
- Exceptional services
- New technologies
- Exceptional skill or experience
- Detailed information
Keys to Successful Differentiation
- Understanding customer needs
- Commitment to customers
- Knowledge of company capabilities
- Innovation
- Competitive advantage calculation formulas (Revenue - Expenses = Gross Margin)
Competitive Advantage Means
- Calculation formulas (Your Company's Revenue - Expenses = Gross Margin; Your Competitors' Revenue - Expenses = Gross Margin)
Best-Cost Provider Strategy
- Margin Components (Value for the client, Margin, Cost)
- Comparing competitors with and without competitive advantage
Low-Cost and Differentiation Strategy
- Margin Components (Value to client, Margin, Cost)
- Comparison of competitors with and without competitive advantage
Building Competitive Advantage

- S-shaped curve
- Annual sales at each stage
Product Life Cycle Considerations
- Introduction (strong R&D focus, increased market share)
- Growth (critical to change price or quality image, strengthening)
- Maturity (competitive costs are critical, defending market share)
- Decline (focus on cost control & driving-through options, may include reduced capacity in terms of products or number of options)
Technology Selection Criteria
- Factors determine choice of technology (technical, market, environmental)
- Firms and countries have specific aspects affecting the choice.
- The more information on alternative technologies and markets, the better the selection.
The S-Curve of Technological Progress
- Stages (New invention, Improvement, Mature)
Learning and Experience Curves
- Describes how efficiency improves with experience
- Measures the reduction in labor hours per unit
- Typical exponential relationships
Example 1 Learning Curve
- Numerical example shows cost reduction with increased production
- Data analysis and calculation methods (e.g., with cumulative numbers of units and hours per unit)
Prices of Integrated Circuits (1964 - 1972)
- Graph showing the price per unit of integrated circuits
- Indicates the relation between price & industry experience (years of production)
Capacity Strategy
- Fundamental Issues (Amount, Timing, Type)
Three Approaches to Capacity Strategy
- Policy A: Maintain excess capacity
- Policy B: Match capacity to demand forecasts
- Policy C: Maximize capacity utilization
Determinants of Capacity Strategy
- Type A: highly competitive industries with product shortages
- Type B: use where power is held by manufacturer
- Type C: for products that quickly become obsolete
Mathematical Model for Timing of Capacity Additions
- Formula to calculate the optimal timing
- Method to balance the cost of operation with the capacity to produce
Mathematical Model (Continued)
- Cost function f(y) depends on k and a showing proportionality and ratio of incremental and average cost per unit
The Function f(u) = u / (e^u - 1)
- Graphing function shows the optimal usage given the relation between u & a
