In reply to Jon Mason.

"what are the metrics that determine a “strong” network" you ask, Jon.

Organizational Network Analysis (ONA) gives us the tools to determine this. From Patti Anklam's book, Net Work, some questions to start looking at value are:

Does the network have adequate resources to create value, both tangible & intangible?
Are there performance metrics for tangible value produced?
Is the network's value-producing model sustainable?
Are all stakeholders receiving the value they expect, and more?
