The Basic Building Blocks of Organizational Structure

Most organizations use a diagram called an organizational chart to visually depict their structure. These organizational charts show how firms' structures are built using two basic building blocks: vertical linkages and horizontal linkages. Vertical linkages tie supervisors and subordinates together. These linkages show the lines of responsibility through which a supervisor delegates authority to subordinates, oversees their activities, evaluates their performance, and guides them toward improvement when necessary. Every supervisor except for the person at the very top of the organization chart also serves as a subordinate to someone else. In the typical business school, for example, a department chair supervises a set of professors. The department chair in turn is a subordinate of the dean.

Most executives rely on the unity of command principle when mapping out the vertical linkages in an organizational structure. This principle states that each person should only report directly to one supervisor. If employees have multiple bosses, they may receive conflicting guidance about priorities and how to do their jobs. The unity of command principle helps organizations to avoid such confusion. In the case of Jim Pattison Group, for example, the head of the Media division reports only to the president. If problems were to arise with executing the strategic move - such as joining the AMC Billboard group with the Media division - the president would look to the chief executive officer for guidance and accountability.

Horizontal linkages are relationships between equals in an organization. Operationally, such linkages take the form of committees, task forces, and teams, and in fact are where the majority of  organizational decisions are first considered for their cross-departmental or overall impact. Horizontal linkages are also important when close coordination is needed across different segments of an organization. For example, most business schools revise their undergraduate curriculum every five or so years to ensure that students are receiving an education that matches the needs of current business conditions. Typically, a committee consisting of at least one professor from every academic area (such as management, marketing, accounting, and finance) is appointed to perform this task. This approach helps ensure that all aspects of business are represented appropriately in the new curriculum.

Organic grocery store chain Whole Foods Market is a company that relies heavily on horizontal linkages. As noted on their website, "At Whole Foods Market we recognize the importance of smaller tribal groupings to maximize familiarity and trust. We organize our stores and company into a variety of interlocking teams. Most teams have between 6 and 100 Team Members and the larger teams are divided further into a variety of sub-teams. The leaders of each team are also members of the Store Leadership Team and the Store Team Leaders are members of the Regional Leadership Team. This interlocking team structure continues all the way upwards to the Executive Team at the highest level of the company". This emphasis on teams is intended to develop trust throughout the organization, as well as to make full use of the talents and creativity possessed by every employee.
