About: Microsoft engineering groups

Microsoft engineering groups are the operating divisions of Microsoft. Starting in April 2002, Microsoft organised itself into seven groups, each an independent financial entity. In September 2005, Microsoft announced a reorganization of its then seven groups into three. In July 2013, Microsoft announced another reorganization into five engineering groups and six corporate affairs groups. A year later, in June 2015, Microsoft reformed into three engineering groups. In September 2016, a new group was created to focus on artificial intelligence and research. On March 29, 2018, a new structure merged all of these into three.
