— USE CASES

What people use Performance review synthesis for

Preparing for rating calibration

Identifies gaps between manager ratings and objective evidence, alongside self-versus-manager differences. Highlights unsupported ratings and cases with missing ratings or evidence for focused calibration discussions.

Examining manager rating patterns

Compares average ratings and distributions across managers and departments, making potential leniency, severity and skew visible without treating those patterns as proof of bias.

Understanding year-on-year movement

Shows rating movement from the prior year alongside current goal attainment and supporting commentary, helping reviewers assess whether changes have a clear evidential basis.

Interpreting written performance evidence

Connects commentary themes and tone to the behaviours being described, using the organisation’s performance framework or a standard framework. Gives reviewers a structured view of qualitative evidence alongside ratings.

What it works from

  • Performance review records with individual references, departments, managers and levels
  • Objectives set and met, with objective scores
  • Self, manager, calibrated and prior-year ratings
  • Written manager commentary on performance and behaviours”

What you get back

  • Performance review synthesis report with reference-only individual identification
  • Goal attainment measures and rating-versus-evidence gaps
  • Self-versus-manager rating differences and prior-year movement
  • Manager average ratings and distribution comparisons by manager and department”

— HOW IT BEHAVES

How Performance review synthesis produces its result

The mechanics behind this specific template — what it reads, what it calculates, and where a human stays in the loop.

Every row of the market being watched

Each row of your export is processed on the same basis, so no signal is skipped however long the table is.

The pattern charted

Movement across the market being watched is visualised from the computed data, so the trend is legible at a glance.

Composed as work product

Findings on the market being watched are written up as a document that reads like professional output, with each claim tied back to a signal.

Roll-up alongside signal-level detail

Detail rows are summarised into the grouped view of the market being watched without losing the underlying signals.

Why this is expensive by hand

Year-end performance reviews combine numerical ratings with commentary that varies in detail, tone and evidential support. In practice it shows up as preparing for rating calibration: identifies gaps between manager ratings and objective evidence, alongside self-versus-manager differences. Highlights unsupported ratings and cases with missing ratings or evidence for focused calibration discussions. It is the kind of work that decides whether a recommendation survives scrutiny — and the kind that quietly eats 3–4 weeks of senior time whenever it comes round.

How this Skill produces it

As a Skill, the work is already sequenced. You bring the evidence, and the run produces performance review synthesis report with reference-only individual identification plus goal attainment measures and rating-versus-evidence gaps. The judgement is built in — how items are broken up, what standard they are held to, and where the run stops for a human review. Net effect: 3–4 weeks down to ~40 minutes, no drift between runs, and every conclusion traceable back to the evidence behind it.

Who it's for

  • CHROs and talent management leads
  • Succession and leadership development teams
  • Executive assessors and coaches
  • Consultants running talent reviews
