Sustainability of the model
● Keep good balance between business & contribution
● Avoid developer overload (super-heroe myth)● Deliver the right software at the right time :
contribution has to be well-managed
27/10/2011 Jérôme PETIT
A few things I would like to share
● Challenging core features are the best choice : they give adrenaline & credibility... if you are good :)
● Manage contribution as any other project in the company... or the inverse
● Check that developers do not forget to sleep

A few things I would like to share
● Community managers & project leaders are COOL
● Give all that you can : 100x returns guaranteed
