Wirearchy, an antidote to many management myths

In an interview with Jon Husband, a techno-anthropologist and strategy and organizational change consultant, he describes the growing phenomena of the wirearchy.

"Husband defines wirearchy as 'a dynamic two-way flow of power and authority based on knowledge, trust and credibility, which is enabled by interconnected people and technology'. A wirearchy isn't a technology or a product. You can't buy it off the shelf. In corporations, wirearchies evolve as company executives, employees, consultants, suppliers and clients, connected by the Internet, freely share information and opinions using a variety of tools from simple email to blogs or wikis."

In the interview he goes on to say;

"People will spontaneously organise for their mutual benefit or a specific purpose, and they'll route around the system if the system doesn't let them do it inside he structure it provides."

This is along the lines that I was wondering in the post "maybe why computer implementations usually fail". If people "route around the system if the system doesn't let them do it inside" then when it comes to implementing a new computer system do we do it the formal system or the way people actually work?
