Measuring Intervention Impact

Every intervention needs a measurement plan defined before it launches. What metric will improve? By how much? By when? Without a predefined success criterion, the intervention lives forever — consuming resources and attention without evidence that it is working. The measurement plan is the accountability mechanism that keeps remediation efforts honest.

Intervention Measurement Plan

Intervention: Mandatory discovery checklist before Proposal stage
Root Cause: Reps proposing before confirming pain, budget, and timeline
Target Metric: Discovery → Proposal conversion rate
Baseline: 42% (February average)
Target: 55% (return to January levels)
Timeline: 6 weeks from deployment
Measurement: Weekly conversion rate for post-intervention cohort

Week 1:  44% (+2)  — Early, expected noise
Week 2:  47% (+5)  — Directional improvement
Week 3:  49% (+7)  — Sustained trend
Week 4:  52% (+10) — Approaching target
Week 5:  54% (+12) — Within range
Week 6:  56% (+14) — Target exceeded ✓

Verdict: Intervention successful. Codify into permanent process.
