## Probability Weighting Prevents Pipeline Inflation **Direct:** Assign deal-stage win rates to opportunities, discount pipeline by actual conversion likelihood rather than counting all deals equally. ### Operator Detail Probability weighting fixes the "assume everything closes" problem that inflates forecasts. Instead of counting a $100K deal in early stage the same as a $100K deal in final negotiation, weight each deal by stage-specific historical win rate. **How it works:** - **Assign win rates by stage:** Prospecting 10%, Qualification 25%, Proposal 60%, Negotiation 85%, Commitment 95% - **Calculate true value:** ($100K deal in Qualification) × 0.25 = $25K weighted value - **Aggregate by confidence level:** Build commit, best-case, and pipeline forecasts from individual deal weights - **Validate against historical close rates:** **Pavilion** and **Bridge Group** research shows reps who weight deals by stage cut forecast error by 30-40% ### Why Traditional Counting Fails Without weighting, a pipeline of 10 early-stage deals ($100K each) = $1M forecast. Reality: at 10% win rate, only $100K closes. Probability weighting reveals the true $100K capacity. ### The CRO Win **OpenView** data shows companies adopting per-stage weighting reduce forecast miss variance by **$200K-$500K** per quarter on million-dollar pipelines. Board reporting becomes credible, not optimistic fiction. ```mermaid graph LR A["Deal: $100K
