The information, insight and errors on measuringusability.com are provided and updated by Jeff Sauro unless otherwise noted. Jeff is a Six Sigma Black-Belt trained Human Factors Engineer at Oracle (formerly PeopleSoft) in Denver, CO, USA. Jeff has been pushing the limits of both usability engineering and Six Sigma for a few years now in the hopes of moving toward more objective implementations of user data. Before Oracle, Jeff was a Human Factors Engineer at Intuit. He received his Six Sigma training at Intuit and at both GE Medical Systems and GE Power Systems. Later he began applying the DMAIC methodology to software development and usability engineering. Education Jeff received his Masters in Learning, Design and Technology from Stanford University. Prior to Stanford, he received his B.S. in Information Management & Technology and BS in Television, Radio and Film from Syracuse University. While at Syracuse he completed a two-year thesis study on web-usability.
