Antecedents of Chaos Engineering

Resilience engineering

Chaos engineering draws from many other fields related to safety, reliability, and control, such as cybernetics, complex adaptive systems, and the study of high-reliability organizations. In particular, the multidisciplinary field of resilience engineering offers a rich area to explore for new directions in chaos $^{2}$. In Drift into Failure [Sid11] Sidney Dekker, one of the pioneers in resilience engineering, talks about “drift” as a phenomenon. A system exists in a realm with three key boundaries, as shown in the figure. In this context, when Dekker talks about systems, he means the whole collection of people, technology, and processes, not just the information systems.
