Most searches fail at calibration, not sourcing.
The brief is where the search is won or lost.
When a senior search drags, the instinct is to blame the market or push harder on sourcing. Usually the real problem is upstream: the brief asked for a profile that doesn't exist, or bundled three must-haves where only one was real. No amount of sourcing fixes a miscalibrated role.
The most valuable hour in a search is the calibration meeting, the one where someone pushes back on the brief and asks which requirements are genuine. It's uncomfortable, and it's exactly the part a speed-obsessed process skips. Get it right and the shortlist appears. Skip it and you search forever.
