Why this is expensive by hand
High performance is often explained through anecdotes or assumptions about what successful people have in common. Defining a hiring profile is the typical trigger — identifies characteristics associated with strong performance in the existing workforce and produces an evidence-based profile to inform hiring criteria. Keeps observed associations distinct from proven predictors of future success. Done properly it is defensible; done at pace it becomes a judgement call nobody can retrace. And "properly" usually means 1–2 weeks of manual work.
How this Skill produces it
As a Skill, the work is already sequenced. You bring the evidence, and the run produces summary of characteristics associated with high performance plus analysis of relationships between workforce factors and the defined outcome. The judgement is built in — how items are broken up, what standard they are held to, and where the run stops for a human review. Net effect: 1–2 weeks down to ~15 minutes, no drift between runs, and every conclusion traceable back to the evidence behind it.
