Speed-to-first-impact = time to ship usable assets into TA workflows and see conversion move.

It’s the time between starting and seeing movement in real hiring metrics. You get there by shipping, not polishing: a clear position for priority roles, proof points, templates (job posts/outreach), and interview + close talk tracks—plus lightweight training so teams actually use them. Speed-to-first-impact is shorter when you narrow scope (one or two role families), avoid committee cycles, and review funnel conversion weekly so you can iterate fast.
