Right on!
As Richard alluded, I was recently in touch with @Dr-G who worked on Internews’ Open Source Software Needs Assessment toolkit – which we discussed here as a potentially relevant counterpart to the components of the Governance Guide that we’ve been (very slowly) developing. Gina has moved on from Internews but gave me a contact there with whom I can follow up.
In my mind, these components – the principles and matrix of questions, plus a needs assessment tool, and also maybe just maybe Community.Rule – could be different components that assemble into something truly valuable. A Governance Guidance Voltron.
