Hi Lorna

Actually that crossed my mind too re the SIGs too.

Thanks Sheila, that’s a really interesting and thoughtful post. Though I confess it was Wilbert’s zombie analogy that gave me that light bulb moment!

” . . . innovation tends to be spread by people who are peripheral in communities”. I think this is a key point for an Innovation Support Centre. We don’t need to be heavily involved in communities to have an impact, but we need to be able to make the right connections.

I think CETIS’ role in making connections between communities is critical to our usefulness as an Innovation Support Centre. And in some ways I think this goes right back to the network of connections, communities and individuals we originally built up through the SIGs. The SIGs may have predated twitter but I bet if we could go back in time and analyse those networks we’d see similar levels of betweeness centrality. To be able to query the data to illustrate these connections is a real step forward though. Fascinating stuff.

thanks Sheila

I will be watching this as am interested in connectedness between projects – useful for synthesis activities…
