# Coach on 1-2 specific peer-relative metric gaps per rep, generic coaching produces generic results

## Claim
Sales managers should run data-driven coaching: for each rep, identify 1-2 specific metrics where they underperform relative to peers (not relative to absolute targets), and build monthly coaching plans around those gaps. Generic coaching ("you're doing well, keep it up" / "do better on discovery") wastes manager time and produces no measurable improvement. Narrow, peer-relative, metric-anchored coaching compounds.

## Mechanism
Coaching has three failure modes that the formula corrects: (a) coaching on too many things at once dilutes effort; (b) coaching against absolute targets confuses motivation problems with skill problems; (c) generic coaching is unmeasurable, so neither manager nor rep can tell if it worked. Narrowing to 1-2 metrics per rep concentrates the coaching effort where it matters. Using peer-relative comparison ("you close at 18%, the team median is 26%, top quartile is 32%") gives the rep a concrete target and exposes whether the gap is a skill issue (the rep can't do what others do) vs. a motivation issue (the rep won't do it). Building a monthly plan with specific actions and a measurable check-in makes the coaching legible to both parties.

## Conditions
Holds when:
- The team has enough reps that peer benchmarks are statistically meaningful (typically 8+ reps).
- Metrics are reliable enough that gaps are real, not artefacts of measurement noise or territory differences.
- Managers have time and skill to run focused 1:1s; this can't be a checkbox exercise.

Fails when:
- Small teams where peer baselines are noisy.
- Metrics are gamed (territory inflation, deal-stage manipulation) and gaps are misleading.
- Managers don't have the analytical fluency to identify the right gap or design the right intervention.

## Evidence
> "The Management Formula uses data-driven coaching where managers identify 1-2 specific metrics where each rep underperforms relative to peers and build monthly coaching plans around those gaps."

## Signals
- Manager 1:1 docs include a specific metric gap and a specific monthly action plan, not generic encouragement.
- Aggregate team metrics improve over quarters as gap-closing produces measurable lift.
- Managers' own performance is evaluated on cohort-level success rate, not only individual-rep attainment (per `ins_skok-sales-rep-failure-rate`).

## Counter-evidence
Pure metric-driven coaching can ignore qualitative dimensions, relationship quality, deal narrative, judgment in ambiguous situations, that don't show up in the dashboard but matter for high-ACV deals. The most senior reps in any org typically need coaching that goes beyond peer-relative metrics; the framework is sharpest for ramping reps and median performers.
