In reply to Mike Pugh.

Leaders have different roles in a networked organization. For example:

Connectivity Network (social network) – “Weaving — Helping people make connections, increase ease of sharing information”
Alignment Network (community of practice) – “Facilitating — helping people to explore potential shared identity and value propositions”
Productivity Network (work team) – “Coordinating — helping people plan and implement collaborative action”
