Causalis Limited – Making Systems Safer

Since 1998 we have offered extensive engineering services for assessing the safety and dependability of technical and sociotechnical systems. We also develop tools and methods for the development and analysis of safety critical systems.

Causalis has developed two methods in-house: Why-Because Analysis for the causal analysis of significant failures and accidents, and Ontological Hazard Analysis for safety analysis during the forward development of critical systems from requirements to software. We also apply industry-standard engineering methods for risk assessment such as Fault Tree Analysis, Event Tree Analysis, and varieties of Hazard Analysis (FMEA, HAZOP, CCA).

We offer a comprehensive software toolset to support Why-Because Analysis, Causal Control Flow Diagrams, and other analytical methods: The SERAS™ toolset. We produce computer-generated videos to illustrate critical engineering events.

Causalis personnel actively participate in international standardisation through the International Electrotechnical Commission of FMEA (IEC 60812), Root-Cause Analysis (IEC 62740), HAZOP (IEC 61882), and the functional safety of systems involving electrical, electronic and programmable electronic subsystems (IEC 61508 Parts 1-7).
