SNA metrics for characterizing the supply network structure

Supply network characteristic	Metric	Implications of a high score for the procurement context
Node centrality	Degree centrality in transactional relationships	Coordinator role: To reconcile differences of network members and align their opinions with the greater supply network goals
	Closeness centrality in transactional relationships	Navigator role: To explore, access, and collect various information with greater autonomy in the supply network
	Betweenness centrality in transactional relationships	Broker role: To mediate dealings between network members and turn them into an advantage
Network centralization	Centralization in transactional relationships	Lack of interactions between central and peripheral firms in a supply network. Decoupled relationships between firms at different tiers
Network complexity	Complexity in transactional relationships	More firms involved in transferring information Active interactions at a local level Slow relaying of communications from downstream to the final assembler
