The Lean and Agile Mindset - Yves Hanoulle and Oana Juncu 2011 « Most of the books and presentations on agile, are about how do we do this or that. That is focusing on HOW. Most people come to me with HOW questions. Yet the solution to their problems is usually in their answers of why they come to me. This presentation is about the why. Why do we do agile. »
