The document discusses the "consumerisation of IT" where trends and technologies originating from consumer markets are increasingly being used in business settings. This is driven by factors like improved mobile devices, cloud services, and changing user expectations of consumer technologies in their personal and professional lives. While this poses risks to corporate IT like security and manageability issues, it also presents opportunities if IT can understand and adapt to these trends rather than fight them. The document provides examples of consumer technologies entering businesses and survey results on the extent companies are seeing this occur independently of IT strategy. It also outlines a balancing act for IT in addressing concerns while embracing opportunities and tips for policies, processes and skills to help manage the consumerisation of IT.
