IT has become integral to many aspects of business, from marketing and customer engagement to new product design. This requires a new way of organizing and engaging across functions.

How important is this cross-functional engagement? It's huge. Seventy-five percent of the 750 respondents to our global survey (see “The Leadership Edge in Digital Transformation," from HBR Analytic Services) say that their company's survival depends on their ability to effectively exploit IT, and almost all — 90% — said that collaboration and communication between IT and other stakeholders in the business is essential to their ability to do so.

Business leaders anticipate dramatic change in all aspects of their operations over the next three years, according to recent research from Harvard Business Review Analytic Services (you can download a copy of the report I authored, Business Transformation and the CIO Role, at the HBR website). Some companies are accelerating this change by committing to IT-enabled business innovation as a core strategy. To understand just how massive the changes will be, consider this: 70 percent of these “innovation accelerators" (about a third of respondents) expect the ways in which they engage with customers to be transformed in three years, rating it eight or higher on a 10-point change scale. That's right: 70 percent. Transformed. Sixty-four percent anticipate that same degree of change in their products and services, their business models and the ways employees work.
