Hierarchical Levels of Strategy

Strategy can be formulated on three different levels:

corporate level
business unit level
functional or departmental level.

While strategy may be about competing and surviving as a firm, one can argue that products, not corporations compete, and products are developed by business units. The role of the corporation then is to manage its business units and products so that each is competitive and so that each contributes to corporate purposes.

Consider Textron, Inc., a successful conglomerate corporation that pursues profits through a range of businesses in unrelated industries.
Textron has four core business segments:

Aircraft – 32% of revenues
Automotive – 25% of revenues
Industrial – 39% of revenues
Finance – 4% of revenues.

While the corporation must manage its portfolio of businesses to grow and survive, the success of a diversified firm depends upon its ability to manage each of its product lines. While there is no single competitor to Textron, we can talk about the competitors and strategy of each of its business units. In the finance business segment, for example, the chief rivals are major banks providing commercial financing. Many managers consider the business level to be the proper focus for strategic planning.

Corporate Level Strategy

Corporate level strategy fundamentally is concerned with the selection of businesses in which the company should compete and with the development and coordination of that portfolio of businesses.

Corporate level strategy is concerned with:

Reach – defining the issues that are corporate responsibilities; these might include identifying the overall goals of the corporation, the types of businesses in which the corporation should be involved, and the way in which businesses will be integrated and managed.
Competitive Contact – defining where in the corporation competition is to be localized. Take the case of insurance: In the mid-1990’s, Aetna as a corporation was clearly identified with its commercial and property casualty insurance products. The conglomerate Textron was not. For Textron, competition in the insurance markets took place specifically at the business unit level, through its subsidiary, Paul Revere. (Textron divested itself of The Paul Revere Corporation in 1997.)
Managing Activities and Business Interrelationships – Corporate strategy seeks to develop synergies by sharing and coordinating staff and other resources across business units, investing financial resources across business units, and using business units to complement other corporate business activities. Igor Ansoff introduced the concept of synergy to corporate strategy.
Management Practices – Corporations decide how business units are to be governed: through direct corporate intervention (centralization) or through more or less autonomous government (decentralization) that relies on persuasion and rewards.

Corporations are responsible for creating value through their businesses. They do so by managing their portfolio of businesses, ensuring that the businesses are successful over the long-term, developing business units, and sometimes ensuring that each business is compatible with others in the portfolio.

Business Unit Level Strategy

A strategic business unit may be a division, product line, or other profit center that can be planned independently from the other business units of the firm.

At the business unit level, the strategic issues are less about the coordination of operating units and more about developing and sustaining a competitive advantage for the goods and services that are produced. At the business level, the strategy formulation phase deals with:

positioning the business against rivals
anticipating changes in demand and technologies and adjusting the strategy to accommodate them
influencing the nature of competition through strategic actions such as vertical integration and through political actions such as lobbying.

Michael Porter identified three generic strategies (cost leadership, differentiation, and focus) that can be implemented at the business unit level to create a competitive advantage and defend against the adverse effects of the five forces.

Functional Level Strategy

The functional level of the organization is the level of the operating divisions and departments. The strategic issues at the functional level are related to business processes and the value chain. Functional level strategies in marketing, finance, operations, human resources, and R&D involve the development and coordination of resources through which business unit level strategies can be executed efficiently and effectively.

Functional units of an organization are involved in higher level strategies by providing input into the business unit level and corporate level strategy, such as providing information on resources and capabilities on which the higher level strategies can be based. Once the higher-level strategy is developed, the functional units translate it into discrete action-plans that each department or division must accomplish for the strategy to succeed.

Strategy Safari organizes the seemingly disconnected aspects of strategic management into 10 different schools

of thought. For example, the basic strategic planning model that was popular in the 1970’s is part of The Planning

School, and Michael Porter’s theories are part of The Positioning School. Strategy Safari provides an overview of

each school and presents a balanced view of each, including advantages and disadvantages. Because of its comprehensive and insightful approach, Strategy Safari presents an excellent overview of the field of strategic management.
