Back of the Napkin

Adjective Phrase · Slang & Abbreviations

Definitions

  1. Describing a rough estimate, sketch, or quick model done informally without much precision. In engineering slang, back-of-the-napkin work is useful for framing decisions early, as long as no one mistakes it for final analysis.

    In plain English: A rough, informal estimate or sketch.

    Example: "The traffic projection was just a back-of-the-napkin estimate, but it was enough to show that the current queue design would probably fall over during launch."
