Paranoia has long been part of the CIO job description. Of course, to quote an old saw, even paranoids have enemies.\n\nToday, the enemy is IT itself. More specifically, it\u2019s the way IT is changing.More on CIO.com\nLet the Business Drive IT Strategy\n\nIT's Third Epoch...and Running IT at Google\n\nNot so long ago, CIOs designed, bought, implemented and controlled IT. Today, as IT permeates every level of the enterprise, as the IT sophistication of users rises, the idea that any one person can control it is becoming increasingly untenable. And that\u2019s bound to make CIOs more paranoid than ever.\n\nFor example, in a survey published last month, more than 600 U.K. IT leaders said their role is becoming less strategic; more than half thought they\u2019d be out of a job within two years. The survey also found that half of their CFOs viewed IT as a support function and as such didn\u2019t believe the CIO needed to occupy a seat on the board.\n\nWell, CFOs have never liked CIOs (CFOs don\u2019t really like anyone) so let\u2019s not worry about them. Let\u2019s worry instead about a recent survey by The Conference Board of 769 CEOs worldwide who said that their top challenge was getting \u201cexcellence of execution\u201d and their third greatest concern was \u201ckeeping consistent execution of strategy by top management.\u201d\n\nSo how\u2019s your execution? It\u2019s hard to execute, isn\u2019t it, when every other employee is downloading his or her own apps off the Web. And it\u2019s hard to enforce a consistent strategy, isn\u2019t it, when business leaders are developing their own based on software-as-a-service offerings that beat your enterprise IT hollow.\n\nSo what\u2019s the answer?\n\nWell, everyone is still working on that. In \u201cLet the Business Drive IT Strategy,\u201d Chris Potts, director of an IT strategy consultancy, suggests that \u201cthe CIO\u2019s challenge is to capture and channel the energy of individuals\u2019 personal strategies for exploiting IT.\u201d That is, be a business facilitator.\n\nIn \u201cIT's Third Epoch...and Running IT at Google,\u201d Google CIO Douglas Merrill basically says that CIOs should play to their technology strength, urging them to have faith in Moore\u2019s Law and \u201cthrow off the shackles of today\u2019s perspective and build the world that we want to live in.\u201d\n\nIn other words, the answer is yet to be determined. But the CIO role isn\u2019t going away. The job is just getting harder to define, harder to do. So what else is new?\n\nEditor David Rosenbaum can be reached at email@example.com.
