This session will present the results from Microsoft Research and Fraunhofer IESE that leverage empirical software engineering. The first talk presents an analysis to investigate various myths in software development. It looks at results from a wide spectrum of studies ranging from testing, cross –project software quality analysis to socio-technical systems. It also presents various aspects of the different software repositories at Microsoft some of which are not obvious and their implications on software development and productivity. Then second talk is on empirical evaluations of human-based software engineering methods which create the scientific basis for “engineering” software and reduce risks of software technology transfer.
