I'm Tris Lumley, and I've worked with charities and funders around impact measurement, research, data and decision-making since 2004. I've seen lots of progress, but been frustrated by knowledge that's siloed, used to compete, and not used for accountability.

I believe we can help create a much more effective, collaborative, powerful, equitable and accountable civil society if we harness knowledge by sharing it. And that only by becoming the open sector can we measure up to the huge challenges we face together.

Open For All is my contribution to helping create an open sector by exploring how we work openly and share knowledge better.
