An I.T. exec who effectively outsourced himself out of a top job at a huge consumer-packaged-goods company seemed more surprised than annoyed by his old firm’s digital strategy.

"They’ve outsourced everything they think isn’t core," he observed. "The problem is, a lot of the stuff the CEO and the management committee says isn’t core, the business units and brand managers do."

The result? This executive, who’s taken early retirement, anticipates a return to the bad old days of "black market" and "gray market" departmental IT budgets. "You just watch," he predicts, "when corporate IT won’t provide them with the system they think they need, the business units are going to go out and build it or buy it themselves. They’re going to do what they think is best for their business regardless of whether headquarters thinks it’s core or not."

Welcome to the dirtiest not-so-little secret surrounding the rise of recentralized IT management and relentless outsourcing: The P&L businesses will build or buy IT anyway. They may do so with their own IT budgets, bootlegged budgets, slush funds, "consultants," college interns, hackers, geeks, toothpicks and sealing wax, but they will get it. Line managers frequently?and understandably?have radically different perceptions than the executives at the corporate pinnacle of what process, products and programs are at their business core.

If corporate history, human nature and Machiavellian enterprise politics are any guide, they’ll also build or buy these systems and apps without either the knowledge or approval of the CIO. This is IT innovation done despite?or in spite of?the CIO. Why? Because CIOs in this era of recentralization, cost-cutting and outsourcing are unambiguously perceived more as managerial overhead than value-added partners. If coordinating with the CIO to deploy a CRM initiative is more costly than beneficial, then the CIO is an enemy, not a business ally.

The result? For a growing segment of P&L executives, the "CI" in CIO no longer stands for "Chief Information"?it’s become the acronym for "Centralized Infrastructure." Centralized infrastructures are more about managing cost than spurring top-line growth and profitability. In other words, business units have powerful incentives to cut the CIO out of the loop. That’s bad news. "The CIOs I know are way too busy putting out fires, cutting costs and supervising SLAs to focus on the particular needs of a particularly entrepreneurial divisional leader," asserts one KPMG managing director. "Line executives who actually want to grow their business are operating in ’better to seek forgiveness than ask permission’ mode. If they think their CIO will help, they’ll ask. Otherwise, they have this attitude of ’Screw ’em....’
