The IT Governance Institute has this excellent webcast – The Challenge of Value .An overview of Val IT 2.0, and an introduction to the challenge of value, the role of IT governance and the challenges of applying Val IT 2.0.
It is presented by John Thorp one of the leading lights as regards the development of ValIT.
John Thorp wrote the Information Paradox a book published in the late 1990s and well worth reading.
I found this webcast well worth listening and watching. There is some excellent material in it.
