Costco Wholesale Corporation’s organizational structure (company structure) represents the functions and interconnections among retail business components, resources, and processes.
The characteristics of this company structure are based on current business operations and facilitate the implementation of retail strategies for business goals that fulfill Costco’s vision and mission.
The competitive advantages and business strengths identified in the SWOT analysis of Costco are supported and maintained through the teams, groups, offices, and departments in this company structure.
Thus, this company structure is a factor in building business competitiveness against other retailers, including Walmart, Aldi, and Home Depot, as well as Amazon and its subsidiary Whole Foods Market.
Considering retail market saturation, this organizational structure is designed to ensure the long-term viability of the business despite the competitive challenges illustrated in the Five Forces analysis of Costco.
Costco’s structure and organizational design suit business needs to overcome such challenges while supporting goals for growth and expansion involving new warehouse-style store locations, new products, and related changes in human resources and the organizational hierarchy.
Characteristics of Costco’s Organizational Structure
Costco has a matrix organizational structure. This type of organizational structure involves a strong function-based aspect and a secondary divisional aspect. The following are the main characteristics of Costco’s organizational structure:
- Hierarchy of function-based departments (primary characteristic)
- Geographic divisions (secondary characteristic)
In the function-based aspect of its organizational structure, Costco groups business components, processes, employees, and other resources according to business function, such as merchandising and finance. In contrast, in the divisional aspect, grouping is based on location or market.
Hierarchy of function-based departments. The function-based characteristic of Costco’s company structure represents basic functions for maintaining the retail business. The main function-based departments at Costco are as follows:
- Office of the CEO
- Administration
- Merchandising
- Finance
- Global Depots and Traffic
- Information Systems
- Legal
These function-based departments reflect the hierarchy in Costco’s organizational structure. Each department has a top executive. Under these executives’ leadership, strategic directives are carried out from the corporate headquarters to the organization’s divisions, groups, and teams.
These departments set goals for strategic formulation for Costco’s competitive strategies and growth strategies. Each department has its own goals and requirements that are factored into strategic decisions for the warehouse club business.
Considering fundamental business functions, each function-based department of this company structure influences various areas of Costco Wholesale’s multinational retail business organization.
For example, the Administration department approves strategic objectives that affect operations management, as well as human resource management and how Costco’s organizational culture (company culture) and its traits are integrated into the divisions of this company structure.
Geographic Divisions. Geographic divisions are an organizational structure feature that relates to the locations of the company’s retail operations. At present, the following are the main geographic divisions in Costco’s business structure:
- Northern Division (U.S.)
- Eastern Division (U.S.)
- Southwest Division (U.S.)
- International Division
Considering that majority of Costco’s warehouse-style stores are in the United States, this organizational structure has three main divisions (Northern, Eastern, and Southwest) for the U.S. retail market.
Also, these divisions have further subdivisions. For example, the Asia Division and the Europe Division are included under the main International Division of Costco’s company structure.
These geographic divisions execute strategies formulated by the function-based departments of Costco’s organizational structure. For example, at the corporate headquarters, the Finance Department sets financial goals that the geographic divisions apply in their respective operations.
In relation, the implementation of Costco’s marketing mix (4P) is adjusted according to market characteristics per region or country through the geographic divisions of this organizational structure.
Through such adjustment, Costco Wholesale Corporation optimizes the success of its marketing strategy in gaining and retaining customers, generating sales, and promoting the company and its brands.
Moreover, through these geographic divisions, Costco’s organizational structure functions as a set of channels for gathering information in market research that targets specific regions or countries where the company operates.
For example, the Eastern Division gathers data on market trends in the Eastern United States. Based on such data, strategies are formulated to ensure that the company’s operations in the region match the region’s retail market dynamics.
Thus, the geographic divisions of this company structure enable decision-makers to gather market-specific retail business information, such as on the economic trends and related external factors identified in the PESTLE/PESTEL analysis of Costco.
Advantages of Costco’s Structure
An advantage of Costco Wholesale’s organizational structure is that the function-based departments support organization-wide communication and managerial control. The company can readily implement new policies and strategies applicable to all geographic divisions.
Also, the geographic divisions of this corporate structure have the advantage of flexibility to adjust Costco’s operations management according to regional or local market conditions in order to optimize business performance.
