Operational Nightmare

Noun · Slang & Abbreviations

Definitions

  1. A system or design that may look acceptable in development but becomes miserable to run, support, and recover in real life. In engineering slang, operational nightmares are why architecture cannot be judged on code elegance alone.

    In plain English: A system that is extremely difficult and painful to operate in practice.

    Example: "The design was clever on paper and an operational nightmare in reality, requiring brittle handoffs and undocumented recovery steps at exactly the worst moments."
