The nature of work keeps evolving. Once, work meant being in the office interacting with colleagues, face-to-face, from 9 a.m. until 5 p.m. Now work happens across corporate boundaries — anywhere, anytime, with people around the world. In the past, work tools comprised only a desk, phone, and computer. Now, work tools include multiple computers and mobile devices — both your own and the ones your company provides. Users don’t just use their own devices for work purposes, they are also turning to Software-as-a-Service (SaaS) providers to fill in functional gaps and boost their productivity.
