AI Engineering Maturity Index

Seven capability domains, five levels, scoring rules and the evidence each level requires — plus the roadmap that converts a score into the next three moves.

AIMI is our own instrument. Its credibility with a technical buyer comes from being explicitly mapped to published research rather than asserted — present it that way, and never imply it is an industry standard.

A worked example. The overall level is the lowest domain, not the average — an average hides the constraint.

The seven domains

#DomainWhat it coversMapped to
D1Stance & governanceA communicated position on what AI may be used for, on what data, with what approval and audit trailClear AI stance; AI governance
D2Context & data accessibilityWhether standards, ADRs and interfaces are discoverable and machine-accessible to assistantsAI-accessible internal data
D3Engineering fundamentalsVersion control discipline, batch size, test strategy, rollback capabilityVersion control practice; small batches
D4Verification & reviewReview capacity, SLOs, depth, provenance-aware review, automated gatesThe verification tax
D5Platform & pipelinePipeline reliability and speed, environment access, self-serviceQuality internal platforms
D6Measurement & valueBaselines, telemetry contract, counter-metrics, attribution, cadenceValue stream management
D7Skills & user-centricityRole-differentiated capability, explain-before-accept, atrophy controlsUser-centric focus

The five levels

Level 1

Ad-hoc experimentation

Individuals use AI; no shared stance, no measurement. Shadow usage; nobody can state the policy; no baseline exists.

Level 2

Standardised tooling

Licences, policy and access standardised; usage reported. Seat dashboards exist; value still unmeasured; review process unchanged.

Level 3

Measured workflows

Baselines and counter-metrics in place; AI provenance captured; the constraint is known and named.

Level 4

Governed, audited delivery

Guardrails enforced by the system; provenance audited monthly; evidence available to auditors; workflows redesigned around verification.

Level 5

Continuous optimisation

Value stream managed continuously; interventions hypothesis-driven; the capability runs without external help.

Scoring rule

A team scores a level only when every domain meets that level. Report the limiting domain alongside the level — "Level 2, limited by D4 and D6" is the sentence that sells the next phase, and it is also the honest one. A domain cannot be scored above 2 on interview evidence alone.

From score to roadmap

CurrentDo next, in orderWhy
1 → 2Publish a stance; consolidate tooling; capture a retrospective baseline before any further rolloutYou cannot amplify what you cannot see
2 → 3Telemetry contract, baseline per team, counter-metrics, provenance taggingUsage reporting is the trap — adoption is an input
3 → 4Verification system redesign, platform SLOs, automated guardrails, provenance auditThe J-curve dip is dominated by verification and pipeline adaptation
4 → 5Value-stream management, hypothesis-driven intervention, internal ownership of the cadenceWhat converts individual gains into organisational performance
