When planning the release of the 2007 Microsoft Office system, formerly code-named Office "12", we took on the challenge of making the core Microsoft Office applications easier to work with. Taking into account extensive usability data and recent advancements in hardware and software, the team has delivered the most significant update to the Microsoft Office user interface (UI) in more than a decade. The result of these efforts is a user interface that makes it easier for people to find and confidently use the appropriate features they need to get the results they want.
