This document discusses social network analysis (SNA) and its application to analyzing relationships between organizations in the machine-to-machine (M2M) sector. It defines key SNA concepts like nodes, ties, and centrality measures. It also outlines benefits of SNA like identifying influential actors, and limitations such as difficulties collecting all relationship data. Visualizations of sample M2M networks show operators have highest degree centrality while application providers have highest closeness centrality. SNA provides a framework for describing complex networks but has limitations like not capturing relationship attributes or motives.
