Kent Sullivan (Principal Consultant)

Kent has spent years fostering deep collaboration among team members and recognizes how hard it is to achieve this in a high-pressure corporate environment. He has coached teams through difficult changes and taught them survival skills for managing the change and thriving in the resulting new situations. Kent also has taught and coached teams on how to integrate lean, customer-centered mindsets and practices into their daily work, so that they greatly reduce the risk of producing something customers don’t need or want. Kent believes strongly that integrating insights extracted from diverse data sources (design research, market research, telemetry, social networking, etc.) greatly increases the chances of those insights being breakthrough in nature. During his long tenure at Microsoft, it was Kent’s pleasure to work on a wide variety of products, especially Windows 95, where he led the exploratory user research that produced the taskbar and Start menu, as well as the iterative research that helped nail down the details.
