What’s Needed for Accurate Revenue Forecasting?
Standardized stages and data, clear forecast categories, a model + judgment approach, and RevOps governance that audits changes and reviews KPIs.

Forecasting Rollout (Copy This Plan)
| Step | What to do | Output | Owner | Timeframe |
|---|---|---|---|---|
| 1 | Publish stage definitions, exit criteria, and field dictionary | Data & stage standards | RevOps lead | 1–2 weeks |
| 2 | Clean pipeline hygiene; lock weekly change windows | Trustworthy pipeline | Sales Ops + Managers | 2–3 weeks |
| 3 | Define forecast categories & default probabilities | Forecast policy v1 | RevOps + Finance | 3–5 days |
| 4 | Stand up model (time series + stage win rates) in BI | Model baseline + dashboards | RevOps Data | 2–4 weeks |
| 5 | Embed rep/manager submissions in CRM with audit trail | Workflow + approvals | Platform/RevOps | 1–2 weeks |
| 6 | Backtest and calibrate monthly; review in MBR/QBR | Error report + adjustments | RevOps + Finance | Ongoing |
Forecast Accuracy KPIs
| Metric | Formula | Target/Range | Stage | Notes |
|---|---|---|---|---|
| Forecast accuracy | 1 − |Actual − Forecast| ÷ Actual | Trending up | Plan | Track by region/segment |
| Coverage ratio | Weighted pipeline ÷ goal | ≥ 3–4× early; ≥ 1× late | Run | By month/quarter |
| Slippage rate | Deals moved out ÷ scheduled | ↓ quarter over quarter | Improve | Signals deal quality |
| Stage win rate | Won ÷ (won+lost) by stage | Stable, calibrated | Analyze | Feeds weighting |
| Forecast variance mix | % error from new biz vs. slip vs. loss | Known & shrinking | Govern | Drives action plan |
Why These Elements Drive Accuracy
Forecasts are only as good as stage discipline and data hygiene. Shared definitions and field controls ensure every deal’s probability reflects reality. A blended approach—statistical baselines from time series and stage win rates, plus rep/manager judgment—captures both historical signal and current context. Governance closes the loop: audits catch sandbagging, backtests calibrate weights, and MBR/QBR reviews adjust assumptions and upstream processes (pricing approvals, contracting SLAs) that create slippage.
TPG POV: We operationalize forecasting as a RevOps program—standards, models, and submission workflows—so leaders gain confidence in the number and teams know how to hit it.

Frequently Asked Questions
Use both: weighted pipeline for early-quarter signal and category submissions for late-quarter commits with accountability and audits.
In CRM with approvals and traces—no side spreadsheets—so changes are auditable and roll up automatically.
Monthly backtests; adjust stage probabilities and category definitions quarterly or when variance patterns shift.
Slippage from poor stage discipline (inflated dates/amounts). Fix with exit criteria, contracting SLAs, and executive deal reviews.
Lean on judgment and analogous win rates, widen confidence bands, and collect fields that quickly improve the baseline.
