Operations Strategy
and
Global Competitiveness
1-2
Overview
1-3
Two Central Themes
1. Customer satisfaction2. Competitiveness• Apple obtained a competitive advantage with
innovation, their production process, and supply chain
• Pepsi example showed that organizations that focus on a few things outperform those that lack focus
• Toyota showed how losing your focus on your strengths can damage competitiveness
1-4
A New Business Environment
• Businesses try to break down the “silos” that used to define business functions.
• Which is the most important department in an organization?
1-5
• Technological progress is moving at a tremendous rate
• There are many new products and services in addition to old ones
• Rapid change is the norm

International Marketplace
• Consumers purchase their products from the providers that offers them the most value for their money
• Many of our products are produced overseas
• Most of our services are provided domestically
1-7
Operations
• Heart of every organization
• Organizations exist to create value
• Operations are the tasks that create value
• Operational innovation can provide organizations with long-term strategic advantages
1-8
The Production System
Figure 1.1
1-9
Operations Defined
• Production system: the conversion process• System: a purposeful collection of people,
objects, and procedures for operating within an environment
• Operations: concerned with transforming inputs into useful outputs according to an agreed-upon strategy and thereby adding value to some entity
1-10
Operations Management
Operations Management – The planning, scheduling, and control of the activities that transform inputs into finished goods and services.
Figure 1.1
1-11
Operations Management
– “The management of resources used to create saleable products and services.”
– The management of an organization’s productive resources or its production system, which converts inputs into the organization’s products and services.
1-12
Systems Perspective
• Inputs• Transformation System
– Alter– Transport– Store– Inspect
• Outputs• Environment
1-13
Inputs
• Inputs include facilities, labor, capital, equipment, raw materials, and supplies.
• A less obvious input is knowledge of how to transform the inputs into outputs.
• The operations function quite frequently fails in its task because it cannot complete the transformation activities within the required time limit.
1-14
Transformation System Transformation System
• The part of the system that adds value to the inputs.
• Four major ways 1. Alter: changed structurally
2. Transport: located somewhere else
3. Store: kept in a protected environment
4. Inspect: understand its properties
1-15
Outputs
• Two types of outputs commonly result from a production system– Services (physical goods) – Products (abstract or nonphysical)
• Any physical entity accompanying a service that adds value is a facilitating good
• Pure service: if there is no facilitating good• Services are bundles of benefits
– Some are tangible and others intangible– May be accompanies by a facilitating goods

Services
Intangible Product or Service
Location, Exchange, Storage, Physiological, Information
Key decisions:
How much customer involvement?
How much customization?

Characteristics of Products and Services
Table 1.1
1-22
Goods, Services, and Products?
• Goods - Tangible products that customers can see, hear, smell, taste, or touch
• Services - Intangible tasks that satisfy the needs of consumers and business users
• Product - Bundle of physical, service, and symbolic attributes designed to satisfy a customer’s wants and needs
• Goods–services continuum - Spectrum along which goods and services fall according to their attributes, from pure good to pure service

Customer Value
• Value = perceived benefits / costs• Perceived benefits can take a wide
variety of forms• Costs…
– Upfront monetary investment– Life cycle costs, such as maintenance– Hassles involved in obtaining the product or
service
1-33
Customer Value (Continued)
• Efficiency = output / input• Productivity: output per worker-hour
– This is a partial factor measure of productivity
– Only includes one productive factor
• Multifactor productivity: uses more than a single factor
• Total factor productivity: uses all the factors of production
1-34
Four Performance Dimensions
Quality
Time
Flexibility
Cost
1-35
Four Performance Dimensions
• Quality– Performance Quality – The basic operating
characteristics of the product or service.
– Conformance Quality – Was the product made or the service performed to specifications?
– Reliability Quality – Will a product work for a long time without failing?
1-36
• Time– Delivery Speed - The ability for the
operations or supply chain function to quickly fulfill a need once it has been identified.
– Delivery Reliability – The ability to deliver products or services when promised.
– Delivery Window
Four Performance Dimensions
1-37
Four Performance Dimensions
• Flexibility– Mix Flexibility – The ability to produce a
wide range of products or services.
– Changeover Flexibility – The ability to produce a new product with minimal delay.
– Volume Flexibility – The ability to produce whatever volume the customer needs.
1-38
Four Performance Dimensions
• Cost
– Labor costs
– Material costs
– Engineering costs
– Quality-related costs
1-39
Quality Dimensions
1. Conformance to specification– Extent to which the product matches the
design
2. Performance– Customers equate quality with
performance
3. Features– Options that a product or service offers
1-40
Quality Dimensions Continued
4. Quick response– Time required to react to customers’
demands
5. Reliability– Probability that a product or service will
perform as intended for a period of time
6. Durability– How tough a product is
1-41
Quality Dimensions (Continued)
7. Serviceability– Ease with which maintenance can be
performed
8. Aesthetics– Factors that appeal to human senses
9. Humanity– How the customer is treated
1-42
Quality’s Benefits
• Customers are more pleased with a high-quality product or service
• More likely to encourage friends to patronize the firm
• Gives firm a good reputation• Allows firm to charge a premium price• Increases market share• Makes follow-up products more attractive
1-43
Quality’s Costs
1. Prevention costs– Including planning, training, design, maintenance
2. Appraisal costs– Measuring, testing, test equipment, inspectors,
reports3. Internal costs of defects
– Extra labor and material, scrap, rework, interruptions, expediting
4. External costs of defects– Ill-will, complaints, correction, warranties,
insurance, recalls, lawsuits
1-44
Customization
• Customization: offering a product or service exactly suited to a customer’s desires– Low customization is called standardization
• Customization demands flexibility• Flexibility: the ability to change or react
with little penalty in time, effort, cost, or performance
1-45
Continuum of Customization
Figure 1.5
1-46
Competitive Advantages of Flexibility
• Faster matches to customers’ needs• Closer matches to customers’ needs• Ability to supply needed items as markets
develop• Faster design-to-market time• Lower cost of changing production• Ability to offer a full line without large
inventories• Ability to meet market demand even with
production delays
1-47
Mass CustomizationMass Customization
• Seek to produce low-cost, high-quality outputs in high variety
• Not all products lend themselves to being customized– Sugar, gas, electricity, and flour
• Is applicable to products characterized by short life cycles, rapidly advancing technology, or changing customer requirements
1-48
Four Mass Customization Strategies
1. Collaborative customizers– Help customers articulate their needs
2. Adaptive customizers– Offer a standard product that customers can
modify themselves3. Cosmetic customizers
– Produce a standard product but present it differently to different customers
4. Transparent customizers– Provide custom products without customers
knowing they are customized

Global Trends
• US imports have grown for more than 30 years
• Exports have increased, but not as fast as imports
• Resulted in exploding trade deficient• US now largest debtor nation in the
world• Cumulative deficit is about ½ GDP

Definitions Corporate Strategy
Business Strategy - The strategy that identifies a
firm’s targeted customers and sets time frames and
performance objectives for the business.
Functional Strategy - A strategy that translates
a business strategy into specific functional areas.
1-54
Vision and Mission Statements
• Vision statements used to express organization’s values and aspirations
• Mission statements express organization’s purpose or reason for existence
• Some organizations may choose to combine the vision and mission statements into a single statement
1-55
Definitions
Mission Statement - Explains why an
organization exists and what is important to the
organization (its core values) and identifies the
organization’s domain.
1-56
The Life Cycle
• Strategies often tied to product life cycle
• Length of life cycles shrinking
• Business strategy should match life cycles stages
1-57
Categories of Business Strategies
1. First-to-market
2. Second-to-market
3. Cost minimization (late-to-market)
4. Market segmentation
Slide on each of these
1-58
First-to-Market Strategy
• Products available before competition
• Strong applied research capability needed
• Can set high price to skim market or set lower price to gain market share
1-59
Second-to-Market Strategy
• Quick imitation of first-to-market companies
• Less emphasis on applied research and more emphasis on development
• Learn from first-to-market’s mistakes
1-60
Cost Minimization or Late-to-Market Strategy
• Wait until market becomes standardized and large volumes demanded
• Compete on basis of costs instead of product features
• Research efforts focus on process development versus product development
1-61
Market Segmentation
• Serving niche markets
• Applied engineering skills and flexible manufacturing processes needed
1-62
Order Winners, Losers, and Qualifiers• Order qualifiers are those dimensions that are necessary
for a firm’s products to be considered for purchase by customers– Features customers will not forego
Order Losers are performance dimension that repel particular customers.
• Order winners are criteria used by customers to differentiate the products and services of one firm from those of other firms– Features that customers use to determine which product to
ultimately purchase

Reasons to Produce OffshoreReasons to Produce Offshore
• Circumvent governmental regulations
• Avoid effects of currency fluctuations
• Avoid fees and quotas
• Placate local customers
1-64
Core Capabilities
• Core competencies: the collective knowledge and skills an organization has that distinguish it from competition
• Core capabilities: organizational practices and business processes
• Should be used to gain access to a variety of markets
• Should be strongly related to key benefits provides by products or services
• Should be difficult to imitate
1-65
Outsourcing
• Subcontracting out production of parts or performance of activities
• Activities and parts fall on a continuum ranging from strategically unimportant to strategically important
• Activities not strategically important are candidates to be outsourced
1-66
Hollowed Out
• The extent that most of a firm’s complex parts and production are outsourced
• Often when complex parts outsourced, engineering talent follows
• Supplier may become competitor
1-67
Productivity Measurement
2-67
Productivity is a measure of how well resources are used
Productivity =Productivity is a relative measure
Must be compared to something else to be meaningfulOperations can be compared to each otherFirms can be compared to other firms
Partial productivity measures compare output to a single input
Multifactor productivity measures compare output to a group of inputs
Total productivity measures compare output to all inputs
1-68
Measures of Productivity (Financial Standpoint)
• What is Net Income?
• Profit Margin – how much profit is generated per dollar of sales
• Return on Assets (ROA) – profit per dollar of assets
• Return on Equity (ROE) – profit per dollar of equity
1-69
• Net income:Net Sales – Cost of Goods sold – Selling and Administrative
Costs - Depreciation – Interest - Taxes
Challenge of Net Income “My business made $50,000 last year” How did I do???
Consider the amount invested to generate the profit:• If I used $10,000 • If I used $1,000,000 • If I used $10,000,000
Net Income
1-70
• Profit Margin
– Income/sales - Profit generated per dollar of sales.– Low costs efficient use of operations resources in processes– High sales high levels of value created by those processes
Evaluating Profitability
1-71
• Return on Assets (ROA)– Net Income/Total Assets– Profit per dollar of assets– Efficient use of resources reduces asset needs– Relevant because operations managers control so many
valuable assets
• Return on Equity (ROE)– Net Income/Total Equity– Productivity of stockholder investment– Less directly applicable to operations managers because ROA
measures the assets themselves• But ultimately how the company is judged by investors
Evaluating Profitability
1-72
• Resource categories:– Inventory– Capacity – Workforce– Facilities– Customer relationships
• Productivity measures for resources are often like local profitability measures.

Exhibit 2.2 Daily orders vs MonthlyOrders to Meet 100 unit/Month Demand
Inventory
• Products and components of products sold
• Average inventory level is basis for productivity measurement.
• Inventory turnover is most common productivity measure.
1-74
Beginning Inv. + Ending Inv.2
Inventory• Inventory turnover is the most common
inventory productivity measure
Inventory Turnover = Net Sales /Average Inventory
• Average inventory level is basis for productivity measurement
1-75
Example 2.1
Deliveries of 800 cases weekly (assume all are consumed evenly during a five-day week)
Cases are valued at $265
• Financial consequences of inventory turnover
Average investment in inventoryWeekly: $106,000Daily: $21,200-------------------------Difference: $84,800
• What is average level of inventory?
• What is average level of inventory if we change from weekly to daily delivery?
Inventory

• Capacity is the capability to produce output in a given amount of time.
• Utilization: Comparison of time spent actually working against theoretical time available to work• Actual running time/time available
Capacity: Utilization
1-77
Capacity: Efficiency• Efficiency
– Efficiency is the comparison of what actually happened to what “should have” happened
– Actual output/ Standard output
Standard = 5400/hour
1-78
• Often the greatest resource
• Often the most difficult resource to manage
• Productivity measurement depends on the objective and the behavior desired.
