Method and tools to drive your open source project with a continuous loop of building measuring and learning, using the constant feedback of your community, experimenting constantly, acting over measured behaviour instead of gut feeling, being ready to accept that you are frequently wrong and should stop investing your time in features nobody wants. The whole idea is relevant for projects that are highly innovating, if you did not took the road less traveled: this talk may not apply to you. There will be a mix of strategy, methodology, organization and architecting but no code, the talk should be accessible for every audience.
