noun
swift decision and action; deciding and acting on the spot
A yojijukugo emphasizing both quick judgment and immediate execution. Often used in business or leadership contexts to praise decisiveness.

リーダーには即断即決が求められる。

即断 means prompt judgment, but 即断即決 combines it with 即決 to stress both deciding and acting quickly.
A yojijukugo composed of 即断 (immediate decision) and 即決 (immediate settlement/action). The exact historical origin is uncertain, but it follows a common pattern of combining two two-kanji compounds with similar meanings for emphasis.
