Methodology

The Model Assurance Lab Method

One principle: before trusting an algorithmic system, try to break it — in a controlled, documented way. The internal engine is proprietary (CoreSyn); the metrics, assumptions and results are documented and reviewable.

1. System context

What the model decides, for whom, and what a failure costs.

2. Data overview

Provenance, representativeness, leakage checks and class balance.

3. Assumptions & limits

What the model is — and isn't — designed to do.

4. Performance

Discrimination and accuracy on held-out data, not the training set.

5. Calibration

When it says 80%, is it right 80% of the time? ECE / reliability.

6. Robustness

Behaviour under noise, perturbation and edge inputs.

7. Bias / fairness

Subgroup performance and disparity across protected groups.

8. Drift

Stability over time and under distribution shift.

9. Fragility

Dependence on a few features, periods or lucky cases.

10. Overfitting

Train-vs-holdout gap and out-of-sample collapse.

11. Operational risk

Latency, cost, failure modes and human-in-the-loop needs.

12. Proof Score + recommendations

One comparable 0–100 number, a verdict and prioritized recommendations.
