How do I diagnose whether a rep needs coaching, training, or termination?

4/30/2024

TL;DR (90-second summary): Pull 4 data points before deciding - ACTIVITY (dials/meetings vs. team percentiles), CONVERSION (funnel stage rates vs. team median), TERRITORY (TAM/ICP fit + prior-rep attainment), TENURE (ramp curve + months in role). Stack the answers; do NOT decide on a single metric. Below 30th percentile activity = coaching. Above-median activity + below-median conversion = training. Two reps failing same patch = territory. >18mo flat with no growth + multiple interventions tried = termination. Bridge Group 2024 pegs replacement cost at 1.5-2x OTE ($270K-$360K for $180K OTE rep), so the math almost always favors coaching first if there's >25% probability of recovery.

The Diagnostic Framework

Firing the wrong rep costs $80K-$360K in turnover + ramp loss (Bridge Group 2024). Keeping the wrong rep costs $200K+ in unrealized quota plus the morale tax - Gallup State of the Workplace 2024 finds one disengaged rep depresses adjacent rep productivity by 11-14%. CSO Insights (Korn Ferry 2023 World-Class Sales Practices Study) reports that organizations who run formal performance diagnostics before action retain 17 percentage points more high-performers vs. those who fire reactively. Gartner's 2024 Chief Sales Officer Survey (G00800431) found 64% of CSOs believe their managers are under-equipped to diagnose performance issues - the data is there but the framework is not. Get the diagnosis right.

STEP 0: CLEAN THE DATA FIRST Before you even open the dashboard:

STEP 1: ACTIVITY (the foundation)

WORKED NUMERIC EXAMPLE - PERCENTILE MATH: Team of 10 AEs, last 30 days, dials/day: [22, 19, 17, 16, 15, 14, 12, 11, 9, 8]

Use the inclusive method (numpy.percentile or Excel PERCENTILE.INC) so all reps see consistent thresholds.

STEP 2: CONVERSION (the skill) Break the funnel into three stages:

ActivityConversionDiagnosisFix
LowHighConfidence/behavior gap30-day activity coach (cadence, time-blocking)
HighLowSkill/training gap3-week MEDDPICC or Sandler bootcamp; reassess
HighHighPerforming - developPromote, mentor, expand patch
LowLowWrong fit, low motivation, or ceilingPIP with crisp exit criteria

ACTIVITY-TO-CONVERSION REGRESSION HEURISTIC: In most healthy teams, activity and conversion correlate at r approximately 0.35-0.55 (Bridge Group, ForceManagement field data). If a rep sits more than 1.5 standard deviations off the regression line, they are either gaming activity (high A, low C) or exceptionally efficient (low A, high C). Both warrant a 1:1 - for opposite reasons.

GONG/CHORUS COACHING SCORECARD (use these dimensions):

If scorecard shows training is the gap, the fix is calibration sessions weekly, not termination.

STEP 3: TERRITORY (the fit)

STEP 4: TENURE (the runway)

EXPECTED-VALUE DECISION MODEL (the math): Let OTE = $180K, quota = $1.2M, current attainment = 58%. Three options:

In this case PIP wins by ~$75K vs keep, and beats fire by ~$639K. Always run the EV math before deciding. If the rep is at 30% attainment and tenure 24mo, fire wins. If at 70% and tenure 12mo, keep wins.

LEGAL / HR RISK CHECKLIST (DO NOT SKIP): Before terminating, run through this with HR and counsel:

The single biggest cause of wrongful termination suits in sales: inconsistent application of standards. If two reps have similar metrics and only one is fired, document why or settle for $50K-$200K later.

REP-PERSPECTIVE TRANSPARENCY FRAME: The rep should be able to answer 3 questions at any point during the diagnostic:

  1. What specific metrics am I being measured on?
  2. Where do I currently stand vs. the bar?
  3. What would I have to do, and by when, to clear the bar?

If the rep can't answer these, the manager has not communicated clearly - and any subsequent termination is procedurally weak. Document the conversation in writing, ideally email or a shared doc.

WHAT TO SAY IN THE 1:1 (verbatim opener): "I want to be direct with you about where you stand and what we're going to do about it. Your YTD attainment is 58% against an expected 80% by month 14. Activity is at 8 dials/day, which is below team 30th percentile of 11. Discovery-to-close is 12% vs. team median of 18%. I don't think this is a fit problem - I think it's a stacked activity-and-skill issue, and I think it's coachable. Here's the 60-day plan I want us to run together. If at the end of 60 days dials are at 14+ and conversion is at 15%+, we're back on track. If not, we'll have a different conversation. I want you to succeed here. What do you need from me?" Calm, specific, falsifiable, supportive. The opposite of a surprise.

REAL DIAGNOSIS EXAMPLE:

PIP LETTER SKELETON (use, don't reinvent):

  1. Specific gap: YTD attainment 58% vs. expected 80% by month 14.
  2. Specific behavioral targets: at least 14 dials/day, at least 6 discovery meetings/week, at least 15% discovery-to-close.
  3. Support offered: 2hrs/week 1:1 coaching + MEDDPICC bootcamp budget.
  4. Timeline: 60 days from [date] to meet all 3 targets.
  5. Consequence: Failure to meet targets results in separation effective [date+60].
  6. Sign + countersign + HR file.

BEAR CASE - when this framework fails you:

  1. Garbage activity data. Reps gaming CRM logs makes percentile rankings fiction. Mitigation: dialer logs only.
  2. Wrong quota. Over-allocated quota by 20%+ makes every rep look broken. Audit quota vs. TAM before diagnosing.
  3. Manager bias. HBR 2023 found managers misclassify 30% of coaching cases as termination cases when they have not ridden along on 5+ calls in the prior quarter. Mandate 5-call shadow before any termination decision.
  4. Macro headwinds. In a down quarter where 70% of the team is missing, individual diagnosis is meaningless - reset the baseline first.
  5. Comp plan misalignment. If SPIFFs reward the wrong behaviors, you are punishing reps for following the comp plan you built.
  6. Survivorship bias in your benchmarks. If you only kept top performers, your team-median is artificially high - any new hire looks bad. Calibrate against industry benchmarks (Bridge Group, Pavilion) too.
  7. Comp-cycle timing risk. Firing a rep who is 60 days from a vesting cliff or accelerator threshold creates legal exposure under wage-and-hour claims AND morale damage. Consult Finance + Legal on timing.
  8. Sample size too small. With <20 closed deals, conversion rate confidence intervals are wide enough to render the diagnosis meaningless. Use Wilson score interval or wait for more data.
