Internal prototype · WTW Annual Salary Increase · 2026

WTW ASI 2026 prototype

Upload a roster. Watch compa ratios, EU Pay Transparency Directive cohort gaps, per-employee peer-median lag, and the merit-pool consequences of every proposal surface themselves — with a regulator-readable explanation attached to every euro.

Six operational steps. One story per employee.

Every decision in the cycle gets a paper trail — not a spreadsheet artefact, but a human-readable rationale a manager, a compensation lead, and a regulator can all read without translation.

1 Step 1 · Ingest

Upload the roster

Drop three files — the roster, a combined pay-ranges file (internal and market bands in one sheet), and an optional Beqom-style adjusted-gap export. The file type is detected from the columns present, so there is nothing to configure, and legacy split internal-only / market-only CSVs still auto-route if that is how your exports arrive. Parsing happens entirely in your browser; files never leave the device. The embedded sample (708 fabricated France + Belgium employees) loads with one click for demonstration.

2 Step 2 · Regulatory picture

Read the EUPTD cohort grid

The default view is a cohort grid grouped by (entity × country × career level) — the directive's "category of workers performing work of equal value" grain. Unadjusted and regression-adjusted gap metrics live in separate column groups so they never read as the same number. Cohorts below the n ≥ 5 per-gender disclosure threshold stay in reading order as greyed "Insufficient data" ghost rows so coverage holes remain visible in the filing.

3 Step 3 · Drill-down

Switch to Landscape, click any dot

The Landscape view plots every employee on compa ratio × performance. Magenta dots flag per-employee peer-median lag — employees who sit below their broad cohort median AND belong to a cohort whose Beqom-adjusted mean gap exceeds 5%. Click a dot or a roster row and the cohort lens floats above the roster with that person's broad peer group (entity × country × career level). A tri-band visualisation then triangulates their pay against the internal pay band, the market pay band, and the peer-cohort percentile — all on a single shared salary scale.

4 Step 4 · Reasoning

Read the reasoning card, not a paragraph

A one-line finding carries a semantic pill (Peer lag X%, Within tolerance, Above median, Insufficient peers). Beneath it, a small options table shows three remediation paths — Legal floor, Cohort median, Retention stretch — each with its FTE-adjusted cost and the residual peer-cohort gap the path leaves behind. The recommended option is tiered by performance: Exceeds and above default to Retention stretch, Meets or below default to Cohort median, and Needs Support defaults to Legal floor so the cycle doesn't reward weak performance with an above-median uplift. An expandable audit narrative holds the full methodology for the regulators who will ask.

5 Step 5 · Decision

Propose salaries, watch the budget cascade

Type a proposed salary on any roster row and tag a justification (Performance, Market correction, Equity adjustment, EUPTD remediation, Retention / Counter-offer, Promotion, Statutory). The discretionary merit pool and the off-cycle pool deplete live based on how the justification routes the uplift. A per-row reset, a running edits ribbon, and roll-up totals mean every decision is traceable before you commit — and every decision arrives with its reason already attached.

6 Step 6 · Traceability

Trace every headline back to a person

Click the Peer-lag stat chip on the cockpit and the roster isolates down to just the flagged individuals whose gaps sum to the headline total. Every euro in the off-cycle pool has a name attached. That is what a defensible filing looks like when you have to explain, line by line, what you knew and what you did about it.

Three beliefs shaped every choice.

None of these are aesthetic preferences. They are methodological commitments that make the output defensible to compensation leadership, human resources, and eventually a regulator.

Defensibility over decoration

Every number produces a sentence a regulator could read. The reasoning is the product; the numbers are the artefact. Reports are designed to be skimmed by comp heads approving decisions and later audited by legal.

Cohorts, not averages

Fairness is a peer concept. Every judgement is relative to a specific cohort — broad (entity × country × career level) for the EUPTD filing, fine (+ job function × family) for per-employee peer-lag drill-down. Never a global mean.

Two signals, clearly separated

The EUPTD unadjusted gender gap at cohort level and the per-employee peer-median lag signal are different metrics, computed differently, read differently, and reported separately. The prototype surfaces both and never lets them read as the same number.

Two gap metrics. One compliant filing.

The EU Pay Transparency Directive becomes enforceable in member states from June 2026. The prototype reports two distinct gap signals — and one separate internal fairness signal — because comp leadership, HR, legal, and regulators each read them differently.

Unadjusted gender gap

At cohort level, per (entity × country × career level). Computed as (mean_M − mean_F) / mean_M, signed, with positive values meaning women are paid less. Flagged when it exceeds 5%. Minimum 5 per gender to disclose, tunable in the app — for example, Denmark's implementing guidance reportedly uses 8 per DISCO-6 group. This is the number the directive wants on your filing.

Adjusted gender gap

Regression-controlled version of the unadjusted gap, typically produced by Beqom or an equivalent analytics vendor. A Beqom-style CSV joins the cohort grid in its own column group, separated from the unadjusted columns by a thin vertical rule so the two metrics never read as the same number. Both live side by side, in the order a regulator would ask about them.

Peer-median lag

A per-employee fairness drill-down, gated on the cohort's Beqom-adjusted gender gap. If the cohort's adjusted mean gap exceeds 5%, below-median individuals in that cohort surface as gap contributors. The gate is the published Beqom value, not a parallel raw calculation — one number, not two. Drives the Landscape's magenta dots and the Peer-lag stat chip on the cockpit. Requires an adjusted-gap export to fire flags; without one the chip is inert, which is a deliberate defer-to-Beqom stance rather than an error.

When the total off-cycle remediation exceeds the pool budget, the cockpit surfaces the overage visually — and in a production cycle the analyst can stage the plan across two or three cycles, labelled explicitly as a Remediation Plan rather than a merit increase. The distinction matters: a regulator will eventually ask whether you knew about the gap and what your plan was. Both answers deserve to be on the record.
