Software Reliability Engineering

Software-reliability engineering (SRE) stems from the needs of software users. The day-to-day operation of our society is increasingly more dependent on software-based systems and tolerance to failures of such systems is decreasing. Software engineering is not only expected to help deliver a software product of required functionality on time and within cost, it is also expected to help satisfy certain quality criteria. The most prominent one is reliability. SRE is the "applied science of predicting, measuring, and managing the reliability of software-based systems to maximize customer satisfaction" [Mus90, Lyu96.
