A legacy system does not need to be rewritten before AI can create value. It does need accessible data, controlled capabilities and enough observability to understand what an integration does. Age is less important than the quality of the boundaries.

A legacy stack is AI-ready when its relevant data is governed, business capabilities are available through stable interfaces, identity is enforced end to end and changes can be observed and reversed.

The assessment should identify the smallest useful workflow, not produce a generic maturity score.

Start with the business job

Choose a task such as retrieving policy, classifying service requests or drafting a project update. Map the current sources, decisions and consequences.

Avoid connecting an AI assistant broadly to “all company data.” Narrow scope improves evaluation, security and time to value.

Define the baseline and severe failure before architecture.

Assess data fitness

Identify systems of record, owners, quality, update frequency and access. Check whether documents are duplicated, permissions are attached and deletion propagates.

For structured data, inspect identifiers, missing values and business definitions. For unstructured knowledge, identify authoritative versions and metadata.

AI will amplify ambiguity in source systems. Fix the material data path rather than launching a company-wide cleansing programme.

Create stable interfaces

Expose needed capabilities through APIs or controlled services. Avoid direct model access to production databases. Use business-level contracts, validation and rate limits.

Where APIs are missing, build an adapter around one bounded capability. Contract tests protect behaviour while the implementation evolves.

Extend identity and permission

Apply the user’s identity through retrieval and tool execution. Test object-level authorization. Give service accounts the minimum permission and rotate credentials.

Separate customer, environment and sensitivity boundaries. Do not rely on the model to decide whether information is allowed.

Review vendor data paths, retention and regional requirements.

Add observability

Trace a request across source, retrieval, model, tool and outcome. Record versions and errors while minimising sensitive logs. Establish current performance before adding AI.

Monitor business outcomes such as correct resolution or completed workflow, not only model latency. Create rollback and fallback to the existing process.

Without observability, an integration can create plausible errors that remain invisible.

Evaluate integration economics

Include adapter development, data maintenance, model use, evaluation, security, human review and support. A seemingly cheap model feature may depend on expensive legacy reconciliation.

Use a pilot to test the highest-risk integration. If value is confirmed, the same boundary can become a modernisation seam.

Score readiness for one workflow

Rate source authority, data permission, API stability, identity propagation, evaluation coverage, observability, rollback and operating ownership. Any critical red score becomes work before release.

The Vinove standard asks whether technology works where people depend on it. AI readiness follows that practical test: can this workflow improve without making the underlying operation less explainable?

Legacy modernisation and AI adoption can reinforce each other. Use the AI workflow to justify a valuable boundary, and use the boundary to reduce long-term coupling. Do not wait for a perfect platform; do not connect around controls that are not ready.

Example assessment output

For a legacy ticketing platform, the assessment may find that ticket text is accessible but customer permissions exist only inside the application, resolution codes are inconsistent and no correlation identifier connects requests to outcomes. The AI idea should not proceed directly to a broad assistant.

The first investment can expose a read-only permissioned search API, standardise several high-volume resolution codes and add tracing. A grounded drafting pilot can then operate on one support queue with human approval.

This sequence creates immediate AI evidence and a reusable modernisation boundary. The readiness assessment becomes a roadmap tied to a workflow, not a score that labels the entire legacy estate unprepared.

Questions for the readiness decision

Can the workflow access authoritative data without bypassing permission? Is the relevant business capability available through a controlled interface? Can the team trace an AI output back to sources and versions? Is fallback to the current process possible? Who operates the integration?

If one answer is no, translate it into a bounded engineering task. Readiness is not a label; it is the set of conditions required for this use case to proceed safely.
