Challenge 1: Technology in the enterprise comes from consumers. Applications such as email and voicemail traditionally sprung from the enterprise itself, with user adoption neatly controlled by IT. Today a lot of technology is coming from consumers directly. Consumers who have been using Web 2.0 tools such as instant messaging, wikis, and discussion forums in their home and social life for years are now the employees expecting the same types of applications in the workplace. What's more, they expect the same levels of performance and ease of accessibility. Add to this the rapid pace of technology, the varied forms of Web 2.0 communications, the sheer amount of content being moved, the increasing mobility of employees, realities of a global workforce (e.g., accommodating varying time zones), and the impact all of this has on your network . . . well, the challenge becomes even greater. How do enterprises keep up with this demand?
