The gauge may change — definitions sharpen, samples grow, cutoffs move. What it may never do is change quietly. Every change to the gauge’s formula or inputs is entered here before it takes effect, with its reason, its approver, and the reading before and after — recalculated on the same week’s counts, so the size of the change itself is visible.
| Entry · Date | Change to the gauge | Reason | Approved by | Reading before → after |
|---|---|---|---|---|
| R-01 Mon Sep 21, 2026 | Gauge adopted, version 1.0: Gauge = A × D × E, read weekly on the Mon–Fri week. The unit is one claim, for one patient visit, entering charge entry and leaving as a verified, submittable claim. | The team needed one agreed number, defined once, before any improvement work began. | Dana — team lead | — → 68.4% First reading, week of Sep 14–18 |
| R-02 Mon Sep 28, 2026 | Unit clarified: a corrected claim re-entering the line counts as the same unit returning, not a new unit in. Step counts on the Gauge Sheet follow this rule from this date. | Corrected claims were being counted twice, which flattered the rolled yield and hid rework. | Dana — team lead | 68.4% → 67.9% Same week recalculated under the clarified rule |
| R-03 Mon Oct 5, 2026 | E’s audit sample doubled, from 25 claims a week to 50, drawn evenly across all five working days. | A 25-claim sample swung E by whole points on a single error; the reading needed to be steadier to be trusted. | June — verification | 67.9% → 67.9% No movement — the change bought steadiness, not a better number |
| R-04 Mon Oct 19, 2026 | A’s denominator clarified: planned hours now include the scheduled Saturday catch-up hours when a Saturday session is rostered, so A cannot be lifted by leaving planned hours uncounted. | A Saturday session in the sample week had been worked but not counted in planned hours, overstating A for that week. | Dana — team lead | 74.1% → 73.5% Week of Oct 12–16 recalculated — the current Gauge Sheet reading |

Why this register is the capstone: a year from now, anyone can open this page and answer two questions exactly — what does our number mean today, and what did it mean on any past week? A gauge whose history is written down can be trusted. One that changed quietly cannot, however good the number looks.
