Why another maturity model?
Existing maturity frameworks tend to focus on quality, cyber or financial dimensions in isolation. Integrity — the combination of provenance, conformance, behavior and governance — is rarely measured as a coherent capability.
This diagnostic introduces five maturity stages, from ad-hoc supplier oversight to a fully instrumented integrity program with continuous assurance.
The five stages
Stage 1 (Reactive): supplier issues handled case-by-case. Stage 2 (Defined): documented qualification and audit cadence. Stage 3 (Managed): risk-tiered oversight with measurable KPIs. Stage 4 (Integrated): integrity controls embedded in design, procurement and aftermarket. Stage 5 (Predictive): continuous monitoring with leading indicators and supplier-shared telemetry.
Each stage includes diagnostic questions, evidence requirements and typical pitfalls.
Using the model
The model is intended as a self-assessment tool rather than a certification. Programs can use it to prioritize investment, benchmark against peers and communicate integrity posture to customers and regulators.
