Moving Target
Noun · Slang & Abbreviations
Definitions
A goal, requirement, or system behavior that keeps changing while people are trying to act on it. In engineering slang, moving targets make honest estimation nearly impossible and create lots of fake failure.
In plain English: A goal or requirement that keeps changing while you try to respond to it.
Example: "The API contract was a moving target during the integration, which is why both teams kept feeling behind even when they were working quickly."
