  The CREST 2018 workshop is the third in a series of workshops addressing
formal approaches to reasoning about causation in systems engineering. The
topic of formally identifying the cause(s) of specific events - usually some
form of failures -, and explaining why they occurred, are increasingly in the
focus of several, disjoint communities. The main objective of CREST is to bring
together researchers and practitioners from industry and academia in order to
enable discussions how explicit and implicit reasoning about causation is
performed. A further objective is to link to the foundations of causal
reasoning in the philosophy of sciences and to causal reasoning performed in
other areas of computer science, engineering, and beyond.
