Network weavers are the people who bring disparate groups together and provide the spark for collaboration, creating a web of connections until a network is formed. Maps that look like constellations pick out the connections forming and show how strong the network is. This poster shows how social network maps change shape as networks develop.
A guide by Network Impact and Center for Evaluation Innovation teaches us that three things matter for effective network functioning, making each an important focus for evaluation: connectivity, health and results. Check out their site which also has a casebook of case studies putting these impact measurement tools into practice.
