Methodology

How we evaluate AI systems

A repeatable process that turns open questions about model quality into evidence your team can act on.

Process

Five stages, every engagement

  1. 01

    Define

    Agree on the decision you need to make, the use cases in scope, risk areas, success criteria and the data we may access.

  2. 02

    Design

    Build test sets, golden sets or task suites and write a scoring rubric with clear definitions and worked examples.

  3. 03

    Calibrate

    Evaluators score a shared pilot set. We compare results, resolve disagreements and refine the rubric before full runs.

  4. 04

    Execute

    Run human, comparative or adversarial evaluation with ongoing sampled review and agreement monitoring.

  5. 05

    Deliver

    Report findings by failure category with evidence, severity and prioritized recommendations — plus the underlying data.

Quality controls

How we keep results reliable

Rubric design

Each score level has a written definition and examples so results mean the same thing across evaluators.

Evaluator calibration

Evaluators are trained and checked on calibration sets before they score live work.

Reviewer agreement

Overlap samples are scored by more than one person; disagreements are adjudicated and tracked.

Quality checkpoints

Sampled second-pass review at defined points, with acceptance criteria agreed upfront.

Traceable findings

Every finding links back to the inputs, outputs and scores that support it.

Confidentiality

NDA-ready scoping; access is limited to the people working on your project.
