variance-analysis（方差分析）

Revenue Variance Analysis Skill

When to Use

• Preparing forecast reviews or board updates that require variance explanations.
• Investigating misses/exceeds across segments, products, or channels.
• Prioritizing remediation plays tied to specific variance drivers.

Framework

1. Driver Taxonomy – classify deltas into volume, conversion, price/mix, churn, expansion, currency.
2. Attribution Logic – define formulas for each driver and maintain consistent baselines.
3. Root Cause Layer – connect drivers to operational issues (pipeline quality, capacity, enablement, macro).
4. Action Mapping – translate each root cause into specific plays with owners and expected impact.
5. Feedback Loop – update forecasting assumptions once variance is understood.

Templates

• Variance waterfall chart setup instructions.
• Driver worksheet (metric → delta → driver → root cause → owner → due date).
• Remediation tracker with status and forecast impact.

Tips

• Keep a glossary so stakeholders interpret drivers consistently.
• Combine quantitative attribution with qualitative context from GTM leaders.
• Feed learnings back to forecast-modeling to tighten assumptions next cycle.
