failure-preventing recommendations
DESCRIPTION
In this talk I gave a brief outline about my PhD work and how I plan to help software developers to avoid introducing failures into software.TRANSCRIPT
Failure-Preventing Recommendations
Adrian Schröter
Dr. Daniela Damian
Motivation
http://www.nist.gov/public_affairs/releases/n02-10.htm
The US economy lost in 2002
60 billion dollar due to software defects
Research Hypothesis
Hypothesis:“The Relation between Social and Technical Dimensions in Software
Development can be used to Create Failure-Preventing Recommendations.”
