| Abstract: | A survey of the relevant literature reveals that a plethora of network analytic facets, such as degree, eigenvalue, density, block, cluster, have been developed and employed to further our understanding of network structures. To extend our understanding of network systems, additional dimensions need to be identified that shed light on the dynamic processes among individual member nodes within network structures. Specific to the context of networked systems, this paper proposes a new concept of fragility. Specifically, it develops and empirically tests a mathematical model of fragility from the standpoint of how ties among network members significantly influence corporate performance, thus uniquely contributing to extant knowledge. Using data drawn from two well-known network organizations, Mazda and Toyota, this research attempts to shed light on the relationship between degree and fragility, to confirm the validity of the new concept as well as enabling a contrast of Mazda and Toyota's network structures. [RM1]Based on the findings, the managerial implications are discussed, the study limitations are identified and directions for further research are suggested. |
