Yesterday a friend sent me the link to a great audiovisual mini-training on Product Ownership, that Henrik Kniberg just published on the CRISP blog http://blog.crisp.se/2012/10/25/henrikkniberg/agile-product-ownership-in-a-nutshell.
It is amazing. It does not only explain important aspects of the Product Owner role is an easy to understand way, but also visualizes central aspects of agile software development like fast feedback, velocity, and release forecast. And all of this in only 15 min!
The technique used reminds me of the famous "RSA Animate" 10 min science videos. One of the most remarkable maybe the one explaining Dan Pink's research about what motivates us. http://www.youtube.com/watch?v=u6XAPnuFjJc
Well done, Henrik!
