When you consider that Microsoft's mission is to enable people to do their best, the importance of usability is clear. This work is as much about people as it is about technology. Fostering usability draws on expertise from varied fields, including anthropology, cognitive psychology, computer science, and educational psychology. Microsoft maintains state-of-the-art facilities (more than 30 participant/observation rooms and five analysis labs) devoted to exploring how customers can better interact with our products.
