Full Functional Safety Lifecycle Support

Functional Safety is not a single activity at the end of development. It is a complete engineering lifecycle that must be planned, executed, documented, verified, and confirmed from the earliest concept phase through production and operation.

Root Cause Technologies supports companies across the complete automotive/rail/industrial Functional Safety lifecycle. Whether you need end-to-end ownership, temporary expert support, independent review, or support for specific work products, we help your teams apply safety engineering in a practical, structured, and standards-oriented way.

Our services cover both Functional Safety Management and Functional Safety Engineering, enabling us to support the organizational, process, and technical aspects of safety-critical development.

Functional Safety Engineering Along the V-Model

The V-Model is central to safety-critical automotive development. On the left side, safety requirements are defined and decomposed. At the bottom, the system is implemented. On the right side, verification and validation activities demonstrate that the implementation satisfies the intended safety requirements.

Root Cause Technologies provides safety engineering support at every stage of this lifecycle.
