Scott came to Microsoft in July 2005. Previously he held various positions at General Electric Co. (GE) for 17 years. He was recognized by CIO Magazine as one of the top 100 CIOs in 2003.
Besides being the CIO for several Microsoft divisions, Stuart also held the position of vice president and executive sponsor for Microsoft’s Operational Enterprise Risk Management.
