Work
Krackhardt developed and showed the consequences of “cognitive social structures”, which capture how networks are perceived in a social environment. He created the E-I index, which describes the extent to which an organization is either silo-like or integrated in its informal structure and demonstrated how these structures affect an organization’s ability to deal with crises. He also developed a set of graph theory-based measures of informal organizations for assessing an organization’s ability to confront a variety of strategic issues. In social network theory, perhaps he is best known for his concepts of “Philos ties” and the “Simmelian tie”, which underscore the importance of, respectively, tie content and the local context in which network relations occur. Methodologically, his major contribution has been the development of the Multiple Regression Quadratic Assignment Procedure (MRQAP), a non-parametric approach to statistical analysis of network data.
