Competitiveness and Globalization:
Concepts and Cases
2. What is strategy?
Provisional definition:
“a coordinated series of actions which involve
the deployment of resources to which one has access
for the achievement of a given purpose.”
2
3. The Strategic Management Process
Involves the full set of:
Commitments Decisions Actions
which are required for firms to achieve:
Strategic Competitiveness
Sustained Competitive Advantage
Above-Average Returns
3
4. Strategic Competitiveness
Achieved when a firm successfully formulates and
implements a value-creating strategy
Sustained Competitive Advantage
Occurs when a firm develops a strategy that competitors are not
simultaneously implementing
Provides benefits which current and potential competitors are
unable to duplicate
Above-Average Returns
Returns in excess of what an investor expects to earn from
other investments with similar risk

6. Challenge of Strategic Management
Only 16 of the 100 largest U.S. companies at the start of the
20th century are still identifiable today!
In a recent year, 44,367 businesses filed for bankruptcy and many
more U.S. businesses failed
Competitive success is transient...unless care is taken to
preserve competitive position

The Industrial Organization model
suggests that above-average returns for
any firm are largely determined by
characteristics outside the firm.
This model largely focuses on industry
structure or attractiveness of the
external environment rather than
internal characteristics of the firm.

44. Bargaining Power of Suppliers
Supplier power increases when:
Suppliers are large and few in number.
Suitable substitute products are not available.
Individual buyers are not large customers of suppliers and there
are many of them.
Suppliers’ goods are critical to the buyers’ marketplace success.
Suppliers’ products create high switching costs.
Suppliers pose a threat to integrate forward into buyers’
industry.
44
45. Bargaining Power of Buyers
Buyer power increases when:
Buyers are large and few in number.
Buyers purchase a large portion of an industry’s total output.
Buyers’ purchases are a significant portion of a supplier’s annual
revenues.
Buyers’ switching costs are low.
Buyers can pose threat to integrate backward into the sellers’
industry.
Buyer has full information.
45
46. Threat of Substitute Products
The threat of substitute products increases when:
Buyers face few switching costs.
The substitute product’s price is lower.
Substitute product’s quality and performance are equal to
or greater than the existing product.
Differentiated industry products that are valued by
customers reduce this threat.
46
47. Intensity of Rivalry Among Competitors
Industry rivalry increases when:
There are numerous or equally balanced competitors.
Industry growth slows or declines.
There are high fixed costs or high storage costs.
There is a lack of differentiation opportunities or low
switching costs.
When the strategic stakes are high.
When high exit barriers prevent competitors from leaving
the industry.

50. Strategic Groups
Strategic Group Defined
A set of firms emphasizing similar strategic dimensions and
using similar strategies
• Internal competition between strategic group firms is
greater than between firms outside that strategic group.
• There is more heterogeneity in the performance of firms
within strategic groups.
o Similar market positions
o Similar products
o Similar strategic actions
50
51. Strategic Groups
Strategic Dimensions
Extent of technological leadership
Product quality

51
52. Competitor Analysis
Competitor Intelligence
The ethical gathering of needed information and data that
provides insight into:
• A competitor’s direction (future objectives)
• A competitor’s capabilities and intentions (current strategy)
• A competitor’s beliefs about the industry (its assumptions)
• A competitor’s capabilities
52
54. Complementors
Complementors
The network of companies that sell complementary products or
services or are compatible with the focal firm’s own product or
service.
• If a complementor’s product or service adds value to the
sale of the focal firm’s product or service, it is likely to create
value for the focal firm.
• However, if a complementor’s product or service is in a
market into which the focal firm intends to expand, the
complementor can represent a formidable competitor.
54
55. Ethical Considerations
Practices considered both legal and ethical:
Obtaining publicly available information
Attending trade fairs and shows to obtain competitors’
brochures, view their exhibits, and listen to discussions about
their products
Practices considered both unethical and illegal:
Blackmail
Trespassing
Eavesdropping
Stealing drawings, samples, or documents
55
56. What Are the Key Factors for Competitive
Success?
KSFs are competitive elements that most affect every industry
member’s ability to prosper in the marketplace
Specific strategy elements
Product attributes
Resources
Competencies
Competitive capabilities
KSFs spell difference between
Profit and loss
Competitive success or failure
56
57. Identifying Industry
Key Success Factors
Answers to three questions pinpoint KSFs
On what basis do customers choose between competing
brands of sellers?
What must a seller do to be competitively successful -- what
resources and competitive capabilities does it need?
What does it take for sellers to achieve a sustainable
competitive advantage?
KSFs consist of the 3 - 5 really major determinants of
financial and competitive success in an industry
57
58. KSFs for Beer Industry
Utilization of brewing capacity -- to keep
manufacturing costs low
Strong network of wholesale distributors -- to
gain access to retail outlets
Clever advertising -- to induce beer drinkers to
buy a particular brand
58
59. KSFs for Apparel Manufacturing Industry
Fashion design -- to create
buyer appeal
Low-cost manufacturing
efficiency -- to keep selling
prices competitive
59
60. Example: KSFs for Tin and Aluminum Can
Industry
Locating plants close to end-use customers -- to keep
costs of shipping empty cans low
Ability to market plant output within economical shipping
distances
60
61. Strategic Management Principle
A sound strategy incorporates efforts to
be competent on all industry key
success factors and to excel on at least
one factor!

Strategic Management
Competitiveness and Globalization:
Concepts and Cases
64. Competitive Advantage
Firms achieve strategic competitiveness and earn
above-average returns when their core competencies
are effectively:
Acquired.
Bundled.
Leveraged.
Over time, the benefits of any value-creating strategy
can be duplicated by competitors.
2
65. Competitive Advantage (cont’d)
Sustainability of a competitive advantage is a
function of:
The rate of core competence obsolescence due to
environmental changes.
The availability of substitutes for the core competence.
The difficulty competitors have in duplicating or imitating
the core competence.
3
66. External Analyses’ Outcomes
Opportunities
and threats
By studying the external environment, firms identify what they
might choose to do. 4
67. Internal Analyses’ Outcomes
Unique resources,
capabilities, and
competencies
(required for sustainable
competitive advantage)
By studying the internal environment, firms
identify what they can do
5
68. The Context of Internal Analysis
Global Economy
Traditional sources of advantages can be overcome by
competitors’ international strategies and by the flow
of resources throughout the global economy.
Global Mind-Set
The ability to study an internal environment in ways
that are not dependent on the assumptions of a single
country, culture, or context.
Analysis Outcome
Understanding how to leverage the firm’s bundle of
heterogeneous resources and capabilities.
6
69. FIGURE 2.1 Components of Internal Analysis Leading to Competitive
Advantage and Strategic Competitiveness
7
70. Creating Value
By exploiting their core competencies or competitive
advantages, firms create value.
Value is measured by:
Product performance characteristics
Product attributes for which customers are willing to
pay
Firms create value by innovatively bundling and
leveraging their resources and capabilities.
Superior value Above-average returns
8
71. Creating Competitive Advantage
Core competencies, in combination with
product-market positions, are the firm’s most
important sources of competitive advantage.
Core competencies of a firm, in addition to its
analysis of its general, industry, and
competitor environments, should drive its
selection of strategies.
9
72. The Challenge of Internal Analysis
Strategic decisions in terms of the firm’s
resources, capabilities, and core
competencies:
Are non-routine.
Have ethical implications.
Significantly influence the firm’s ability to
earn above-average returns.
10
73. The Challenge of Internal Analysis (cont’d)
To develop and use core competencies,
managers must have:
Courage
Self-confidence
Integrity
The capacity to deal with uncertainty and
complexity
A willingness to hold people (and themselves)
accountable for their work

92. Value Chain Analysis
Allows the firm to understand the parts of its
operations that create value and those that do
not.
A template that firms use to:
Understand their cost position.
Identify multiple means that might be used to
facilitate implementation of a chosen business-
level strategy.
30
93. Value Chain Analysis (cont’d)
Primary activities involved with:
A product’s physical creation
A product’s sale and distribution to buyers
The product’s service after the sale
Support Activities
Provide the assistance necessary for the primary
activities to take place.
31
94. Value Chain Analysis (cont’d)
Value Chain
Shows how a product moves from the raw-
material stage to the final customer.
To be a source of competitive advantage, a
resource or capability must allow the firm:
To perform an activity in a manner that is superior
to the way competitors perform it, or
To perform a value-creating activity that
competitors cannot complete
32
98. The Value-Creating Potential of Primary Activities
Inbound Logistics
Activities used to receive, store, and disseminate
inputs to a product
Operations
Activities necessary to convert the inputs provided
by inbound logistics into final product form
Outbound Logistics
Activities involved with collecting, storing, and
physically distributing the product to customers
36
99. The Value-Creating Potential of Primary Activities (cont’d)
Marketing and Sales
Activities completed to provide the means
through which customers can purchase products
and to induce them to do so.
Service
Activities designed to enhance or maintain a
product’s value
Each activity should be examined relative to
competitor’s abilities and rated as superior,
equivalent or inferior.
37
100. The Value-Creating Potential of Primary Activities:
Support
Procurement
Activities completed to purchase the inputs
needed to produce a firm’s products.
Technological Development
Activities completed to improve a firm’s product
and the processes used to manufacture it.
Human Resource Management
Activities involved with recruiting, hiring, training,
developing, and compensating all personnel.
38
101. The Value-Creating Potential of Primary Activities:
Support (cont’d)
Firm Infrastructure
Activities that support the work of the entire value
chain (general management, planning, finance,
accounting, legal, government relations, etc.)
• Effectively and consistently identify external
opportunities and threats
• Identify resources and capabilities
• Support core competencies
Each activity should be examined relative to
competitor’s abilities and rated as superior, equivalent
or inferior.
39
103. Outsourcing
The purchase of a value-creating activity from
an external supplier
Few organizations possess the resources and
capabilities required to achieve competitive
superiority in all primary and support activities.
By performing fewer capabilities:
A firm can concentrate on those areas in which it
can create value.
Specialty suppliers can perform outsourced
capabilities more efficiently.
41
104. Outsourcing Decisions
A firm may outsource all or only
part of one or more primary
and/or support activities.

Helps a company focus on broader business
issues by having outside experts handle
various operational details.
Providing access to world-class
capabilities
The specialized resources of outsourcing
providers makes world-class capabilities
available to firms in a wide range of
applications. 43
106. Strategic Rationales for Outsourcing (cont’d)
Accelerating re-engineering benefits
Achieves re-engineering benefits more quickly by
having outsiders—who have already achieved
world-class standards—take over process.
Sharing risks
Reduces investment requirements and makes firm
more flexible, dynamic and better able to adapt to
changing opportunities.
Freeing resources for other purposes
Redirects efforts from non-core activities toward
those that serve customers more effectively. 44
107. Outsourcing Issues
Seeking greatest value
Outsource only to firms possessing a core
competence in terms of performing the primary or
supporting the outsourced activity.
Evaluating resources and capabilities
Do not outsource activities in which the firm itself
can create and capture value.
Environmental threats and ongoing tasks
Do not outsource primary and support activities
that are used to neutralize environmental threats
or to complete necessary ongoing organizational
tasks. 45
108. Outsourcing Issues (cont’d)
Nonstrategic team resources
Do not outsource capabilities critical to the
firm’s success, even though the capabilities
are not actual sources of competitive
advantage.
Firm’s knowledge base
Do not outsource activities that stimulate
the development of new capabilities and
competencies.
46
109. Cautions and Reminders
Never take for granted that core competencies will
continue to provide a source of competitive
advantage.
All core competencies have the potential to become
core rigidities—former core competencies that now
generate inertia and stifle innovation.
Determining what the firm can do through
continuous and effective analyses of its internal
environment will increase the likelihood of long-term
competitive success.

123. Những khó khăn
của việc quản trị chiến lược
Ngày nay chỉ còn 16/100 các công ty lớn nhất
của Mỹ kể từ đầu thế kỷ 20 là còn giữ được vị
trí của mình.
Trong những năm gần đây, 44,367 doanh nghiệp
nộp đơn xin phá sản và ngày càng nhiều doanh
nghiệp Mỹ thất bại.
Thành công trong cạnh tranh không phải là vĩnh
hằng… trừ khi chúng ta biết cách giữ được vị
trí đó. 6
124. Những khó khăn của việc quản trị chiến lược
Mục tiêu đạt được lợi thế chiến lược cạnh tranh và đạt
lợi nhuận trên mức trung bình là rất khó khăn.
Hoạt động của một công ty không chỉ là để vượt qua
được những khó khăn về mặt chiến lược

Lợi thế cạnh tranh của một quốc gia chỉ có thể đạt được bằng
quá trình tích hợp lợi thế cạnh tranh chiến lược của từng
công ty thuộc quốc gia đó trong nền kinh tế toàn cầu.
Một quốc gia có lợi thế cạnh tranh tốt sẽ giúp người dân
nước đó có mức sống cao hơn.
