This page describes a designed model, not shipped behaviour. The mechanism is specified; no surface records transitions from your data yet.
What it takes to record one
A transition is recorded at 70% confidence or above. Below that it is flagged as low-confidence and routed for review, and the stage does not move. A stage that has not moved is a stage Beacon could not confirm — not a stage that stayed put. Backward moves are ordinary. An account or deal can return to an earlier stage, and that is recorded like any other transition rather than corrected away.What moves the moment it is recorded
The clock restarts. Days in stage counts from entry into the current stage, so it returns to zero at every transition. The days spent in the previous stage are kept. The comparison re-anchors. Pace is judged against a benchmark held per segment and stage. A deal entering a new stage is immediately compared against a different distribution — which is why the same 45 days can be unremarkable in one stage and a serious signal in another. The stall band recomputes. Against the median for that segment and stage: under 1.0× is not stalled, 1.0–1.5× is approaching stall, 1.5–2.5× is stalled, and beyond 2.5× is severely stalled. The percentile recomputes. Deal velocity percentile is re-ranked daily against the new stage’s distribution. A low number is fast. Progression health re-reads pace. How promptly a record moves between stages is the heaviest single input into the health score, so a transition changes the score even when nothing else about the account has changed.Where the benchmark comes from
From your own closed deals, not from an industry table — a rolling twelve months, recalculated quarterly. A segment-and-stage pairing needs at least 10 closed deals before it produces an empirical benchmark and 30 before it is treated as high confidence. Below that, Beacon uses template defaults and labels them as such. The thresholds sit on the median rather than a higher percentile on purpose: the median is what separates the half of deals moving materially slower than typical from the half that are not. A higher bar would only flag the extremes.What does not change
A transition does not change the segment, does not change the stage set, and does not retrospectively alter any figure already sealed for a closed period. Scores move because a stage moved; a stage never moves because a score did.Related
