Functional safety consulting focuses on system behavior under single or multiple fault conditions.
"Functional safety is part of the overall safety that depends on a system or equipment operating correctly in response to its inputs." (IEC)
The reasons a system or device does not behave correctly may have several causes:
- Random faults of components or subsystems
- Systematic faults in hardware, software or architecture (i.e. software bugs, timing problems)
- Incorrect operation or maintenance
- Incorrect or incomplete definition of system behavior during design and testing
The functional safety of any system depends on proper hazard identification and mitigation, correct implementation and thorough verification and validation. System Safety, Inc. assists during all steps of the design lifecycle to achieve a functionally safe design and implementation.
