Include both management personnel as well as individual contributors on your SharePoint governance committee. This will aid in the decision making processes by providing deeper, more relevant context to the discussions.

From the management personnel, a higher level, strategic view of the business will be represented, which will serve to inform where the business is going, some of the elements that it is hoped that SharePoint will address and the path that is planned to move the organization to the next level.

From the individual contributors will come a focus on the practical application of the technology and how the user community will actually integrate SharePoint into their daily work.  When I work with organizations I often try to spend most of my time with the individual contributors, the people that focus on where the rubber meets the road.  These are the people that are planning and executing the vision set forward by management.  SharePoint is very much a ‘hands on’ technology that flourishes when stretched and molded.  It often takes the worker community a little longer to get SharePoint configured exactly the way that they want it, but once it is, beautiful things happen.
