mission-critical
Failure means disaster
Mission-critical describes systems, tasks, or functions essential to an operation's success—if they fail, everything fails.
The term originated in aerospace and military contexts, where mission-critical equipment could mean the difference between success and catastrophe.
It has spread to business and technology: The database is mission-critical; we need 99.99% uptime.
Often used to justify resources or urgency.
