The article studies corporate evolution by performing a longitudinal analysis of Unisys Corporation and its alliance network, using interviews, questionnaires and archival data sources to identify four phases of evolution. The article states that little is known about the evolution of interconnected firms that are embedded in alliance networks. The article details the four phases that were formed by the coupling of corporate strategy and the alliance network. The study finds that the adaptation of the Unisys' network configuration followed corporate strategy, but was gradual and emergent.
