Yves is an avid member of the Agile and Lean community. This is quite public because he speaks at conferences, blogs and tweets a lot, but to me smaller, less obvious traits are more important:
– Yves is a FirstFollower. He has the passion and curiosity to identify potential movements and support them. Best example: When Marc Löffler and Marcin Floryan started the discussion on LinkedIn to have an Agile Lean Europe conference, Yves stepped ahead and gave it a name (ALE2011) that inspired discussion and organisation up until it actually happened.
– Yves offers life-time support for everything he does. No questions asked.
Yves is a true linchpin, changing the world one step at a time.
