| Summary≠ | Structural holes analysis, developed by Ronald Burt, measures the brokerage opportunities available to an actor by examining the gaps — structural holes — between their otherwise disconnected contacts. An actor whose contacts do not know each other bridges non-redundant sources of information and control and is said to be rich in structural holes; an actor whose contacts are all interconnected is constrained. The core measures — network constraint, effective size, and efficiency — quantify how much advantage an ego's network structure confers. | Social Network Analysis (SNA) is a structural method that maps and measures relationships and flows between people, groups, organizations, or other entities modeled as nodes connected by ties (edges). Rather than focusing on individual attributes, SNA reveals how the pattern of connections shapes behavior, influence, information flow, and outcomes within a system. |
