fault-tolerant
Survives component breakdowns
Fault-tolerant describes systems designed to continue operating even when components fail.
A fault-tolerant computer might use redundant processors so that if one crashes, another takes over seamlessly.
The term appears in engineering, computing, and aerospace: The spacecraft's fault-tolerant design saved the mission.
By extension, fault-tolerant can describe any process or organization that absorbs errors without collapsing.
