Performance Review & Calibration Platform
Executive Problem & Decision SnapshotSanitized Demonstration
The Business Problem
Previous evaluation prototypes relied on browser-side auth and unconditional Z-Score normalization, risking unfair automatic score overrides in a small-sample organization.
The Chosen Decision & Architecture
Built weighted multi-rater assignments, immutable cycle snapshots, mandatory HR calibration rationale, and statistical signals as reference rather than automatic verdicts.
"Use data to make rating differences visible; keep formal calibration explainable and reviewable."
Key Evidence Points
- 107 verified tests across API, web, and contract layers
- Role-based visibility: Employee, Reviewer, HR, and GM approver
- Clear scope separation: Implemented Foundation vs. Designed Calibration
