Each of these trends described in this issue is powerful on its own and requires devoted study from IT planners and leaders. Taken collectively, they can be a rather large tsunami that engulfs organizations faster than they can adjust. 2012 will likely emerge as a critical transition year in which two well-established trends, social media and consumer technology, meet up with two emerging trends, Big Data and cloud computing, and transform corporate IT from the inside and the outside. There is a lot of promise and peril in these trends. To some, they represent the beginning of the end of the modern IT organization. I -- and I think our authors -- would disagree. This is merely the end of the very early phase of an important transformation that will require all the best and brightest IT leaders across the globe. New tools enable new strategies, and, boy, do we have new tools available to us in 2012! To sort this out, I encourage you to read on and learn how these trends will impact you and your organization.
