Hello,
I did recently a webcast about MBV for the UK SOA/BPM User Group (SBUG)
Link to the video is available here : http://geekswithblogs.net/michaelstephenson/archive/2009/10/13/135448.aspx
I would like to thank Michael Stephenson for this web cast invitation which was a good opportunity for me to explain MBV goal and its usage and do some Q&A with participants !
