What does ‘wood behind the arrow’ mean?

Wood behind the arrow is operational jargon — especially in sales and engineering — for putting concentrated resources behind a single strategic initiative rather than spreading effort thinly across many. The metaphor refers to the wooden shaft that gives an arrow its mass and force on impact.

Phrased as ‘we need more wood behind that arrow’, the term signals that an initiative is under-resourced relative to its strategic importance. Discipline in ‘wood-behind-the-arrow’ allocation distinguishes focused executives from those running too many parallel bets.
