It’s Not You, It’s Your Job: Network Evolution within Firms

People centrally located within networks enjoy a variety of benefits. Why some people achieve such advantage while others do not is not well understood. Using a novel dataset that maps the workflow network among software engineers at a Fortune 500 technology company, I trace the evolution of the position of 804 new entrants to the firm over a period of three years. Findings paint a consistent picture as to the determinants of position in this network: one’s team and one’s job at time of entry, rather than intellectual or social endowment, play the strongest roles in determining one’s subsequent centrality and autonomy.
