Corporate Implementation of Social Networks - Is there a methodology?

A recent blog post (here) discussed the costs associated with corporate implementation of social networking applications. The post went on to indicate that corporate adoption is an ongoing issue and the price of implementation is 75% process related and 25% technology. This imbalance is common with software implementations so I am not surprised.

I wonder if social networking application platforms are implemented using a specific type of methodology. Success of these systems is based upon user adoption, informational value and the productivity gains touted by the vendors of these systems. Theoretically, the incredibly low price of procuring these systems should provide companies with easy justification using ROI and payback period estimations. But how do these companies promote usage and adoption of their product? Mature organizations are usually managed by personnel reluctant to adopt web 2.0 functionality. Some still view the computer as a cost center that provides no business benefit.

If anyone has heard of a social network implementation methodology to facilitate user adoption I would like to know about it. Until then the return on investment is reflective in the procurement price of these systems = low.
