Failure Consequence Assessment System (FCAS) was a methodology used by the Federation for determining how and why a spacecraft might fail and what the consequences of that failure might be.

Galen Pizzorno, the deputy mission director for the SS Artemis, was trained in this system. (TNG: "The Ensigns of Command")

FCAS was mentioned in the mission summary for Artemis.
This system has been used by NASA since the 1960s.
