Fail Fast

In system design, a fail-fast system is one which immediately reports at its interface any condition that is likely to indicate a failure. Fail-fast systems are usually designed to stop normal operation rather than attempt to continue a possibly flawed process. https://en.wikipedia.org/wiki/Fail-fast

• The term has been widely employed as a metaphor in business, dating back to at least 2001,[1] meaning that businesses should undertake bold experiments to determine the long-term viability of a product or strategy, rather than proceeding cautiously and investing years in a doomed approach. It became adopted as a kind of "mantra" within startup culture, i.e. "Fail fast, fail often."
