Scoring Methodology Overview

Framework Purpose

The Valuation Stability Standard (VSS) is an independent analytical scoring framework designed for structural durability assessment of business models. The methodology quantifies stability signals across five pillars to produce a composite stability score.

Scoring Architecture

Each pillar score is derived from weighted signal inputs. Signals are normalized and scored against defined breakpoints. The composite VSS score aggregates pillar scores using documented weight distributions.

The model applies asymmetric adjustments through the Multiple Pressure Index (MPI) to account for compounding fragility or strength signals.

Deterministic Processing

All scoring logic is SQL-native and deterministic. Given identical inputs and model version, outputs are fully reproducible. No probabilistic or machine learning estimations are applied to final scores.

Integrity Controls

Submissions undergo anomaly detection and cross-field consistency validation. Integrity flags are raised when input patterns suggest data quality issues. Severity thresholds determine certification eligibility.

Grade Classification

VSS scores map to letter grades (AAA through C) based on defined score thresholds. Grade bands are documented in the model registry and versioned with each model release.

VSS Grades represent structural durability classifications under the VSS model framework and are not credit ratings.

Benchmark Gating

Percentile positioning requires minimum verified cohort thresholds. When cohort requirements are not satisfied, benchmark data is withheld to preserve statistical reliability.
