"What is it in your business that's not driving you to do things better, faster, cheaper?" asks Mike Zill, CIO of CareFusion. These were the questions that the large health care technology company was asking itself when it decided to add an HR cloud-based solution. By allowing for drastically increased mobility, scalability, and intuitive interfaces, CareFusion has entered the cloud and never looked back. Now the company can't help but to see SaaS in a new light.

Why wouldn't you add cloud-based SaaS solutions? Well, according to Zill, "you must be in some business that doesn't have any pressure, nothing to do with speed, nothing to do with cost, nothing to do with improvement. And I just haven't seen one of those businesses."
