Software Reliability Engineering -- Risks, Challenges and Chances for Product and Process Improvement

Software Reliability Engineering (SRE) refers to those software production processes that design reliable performance and functionality into information & knowledge processing systems. In short, SRE seeks to build such systems that do exactly what we want, not only once, but measurable many times. The question is whether a general risk management (which we want, including the aspects of safety, security, etc.) can be achieved and measured by the approaches used in SRE. If not, why not? If so, how?
