01Problem

A model team needed dependable human judgment on multi-step coding tasks, but ad-hoc grading produced noisy, unrepeatable signals.A model team needed dependable human judgment on multi-step coding tasks, but ad-hoc grading produced noisy, unrepeatable signals.

02Approach

1. 01

   Decomposed tasks into scoreable dimensions with worked calibration examples.

2. 02

   Ran paired grading with adjudication and tracked inter-rater agreement per dimension.

3. 03

   Built adversarial probes targeting known failure modes and regression suites.

4. 04

   Delivered weekly reports with drift analysis and rubric revisions.

03Outcome

• Agreement metrics stable enough to use as a release gate.
• Regression suite reused across successive model versions.
• Rubric adopted as the team's internal standard.
