Waterfall Model
A demand generation framework that tracks how marketing-sourced leads flow through sequential stages -- from raw inquiries to MQLs, SALs, SQLs, and pipeline -- with clear conversion benchmarks at each step.
A Waterfall Model in Revenue Operations (RevOps) is an analytical framework that explains how pipeline and revenue targets are built and changed over a period of time. Instead of just showing how much pipeline or revenue you have at a single moment, it shows how you got there.
How a Revenue Waterfall Works
Over a quarter (or month), a revenue waterfall tracks:
- Beginning pipeline – The total pipeline already in place at the start of the period.
- Pipeline created – New opportunities added during the period.
- Pipeline pulled in – Deals originally forecasted for future periods that were accelerated into the current period.
- Pipeline pushed out – Deals that slipped from the current period into future periods.
- Pipeline lost – Opportunities that were closed-lost or disqualified.
- Pipeline reduced – Deals that decreased in value (down-sized) during the period.
- Pipeline increased – Deals that increased in value (up-sized) during the period.
- Closed-won – Revenue that actually closed in the period.
By combining these components, the waterfall reconciles how you moved from your starting pipeline to your final closed-won revenue and ending pipeline.
Why the Waterfall Model Matters
The waterfall exposes the story behind the revenue number. For example, a company might close $2M in a quarter, but the waterfall could show:
- $3M beginning pipeline
- $1.5M pipeline created
- $2M pipeline lost
- $500K pushed out
This reveals that hitting $2M required overcoming significant loss and slippage, and that some of the potential was simply delayed, not gone. This level of detail enables:
- Better forecasting (understanding what’s likely to close and when)
- Stronger pipeline management (knowing where deals are leaking or stalling)
- Clearer performance diagnosis (is the problem creation, conversion, slippage, or loss?)
Waterfall vs. Snapshot Reporting
- Snapshot reporting shows pipeline at a single point in time (e.g., “We have $5M in pipeline today”).
- Waterfall reporting shows how pipeline changed between two points in time (e.g., “From the start of the quarter to now, here’s what was added, lost, pulled in, pushed out, increased, and reduced”).
Because it captures movement and direction, the waterfall is far more diagnostic. It answers:
- What changed?
- By how much?
- In which direction (forward, backward, up, down)?
- Why did it change (loss, slippage, expansion, etc.)?
RevOps Application
RevOps teams typically:
- Build and maintain the revenue waterfall model.
- Update it weekly or monthly as a core operational report.
- Use it in:
- Pipeline reviews – to understand deal health and risk.
- Forecast calls – to validate whether the forecast is realistic based on movement patterns.
- Trend analysis – to identify recurring issues like chronic slippage, high loss rates, or insufficient new pipeline creation.
Because it connects starting pipeline, in-period changes, and final outcomes, the waterfall is one of the most powerful tools RevOps has for improving forecast accuracy and controlling the health of the revenue engine.
