Abstract:

An organizational structure consists of a network where employees are connected by working and social ties. Analyzing this network, one

can discover valuable insights into information flow within the organization. We develop this idea and propose a simple network model that

is consistent with management theory, and that captures main traits of large corporations. Using a centrality-based definition of power,

we are able to identify important individuals in the network. Our model provides novel insights into a range of organizational properties.

(1) Organizations have limited hierarchy height. (2) Flattening, the process when a business changes from a tall to a flat hierarchy by

delayering, is intimately related to changes in the power of employees. (3) Informal relations significantly impact power of individuals.

(4) Leadership styles could be reflected and analyzed through understanding weights on the ties in an organizational network.
