The document discusses maximizing business value from IT. It outlines the author's journey working in the IT field since the 1980s and developing a method called BVMF® for achieving maximum business value. It describes three eras of how IT delivers business value and compares various methods. The key point is that while methods like Agile and Waterfall address parts of the problem, they are missing the "elephant in the room" which are the underlying principles for how IT leads to business value. BVMF® aims to provide this missing piece by focusing on business objectives and processes rather than software outputs.
