SYSML16 — Lightweight representations of faults, failures, hazards and off-nominal conditions and behavior

There is a critical need to model off nominal conditions and behavior associated with faults, failures, and hazards. However, there currently is no standard way to represent this in the SysML model. This issue is intended to provide some lightweight and standardized and light-weight capability for this type of modeling, such as a trigger on a state machine with the stereotype failure or a fault stereotype to represent a fault condition. There is a separate profile (not standardized) that was developed by Bruce Powell Douglass that provides a broader more comprehensive capability that could be leveraged as source material.

Out of scope

Architecture of SysML20 will address if libraries will be a concept supported by it.
Such a library/profile is a perfect candidate for SysML20.
Although closer to Systems Engineering, it might also be a candidate for UML.

Trace it to SysML20.
