Thanks to IT, organizations are more sophisticated and agile than ever in improving processes, developing products, and approaching customers. But for every action there is a reaction. Each of these improvements has required greater specialization, causing the IT unit to focus on cultivating greater expertise in the functions it supports. That could mean greater communication within the business unit, but more often means less communication between business units. In short, silos develop and opportunities are missed because people aren’t aware of what’s going on in other parts of the organization.
