Architecture documentation for regulated industries

Financial services, insurance, healthcare and pharmaceuticals share a structural requirement: architecture has to be auditable, the audit evidence has to be current, and drift between the architecture and the documentation has to be demonstrable. NeoArc treats this as a structural property, not a quarterly exercise.

In regulated industries, compliance evidence is usually assembled retroactively. A few weeks before an audit, architects and compliance officers pull snapshots from tools that have moved on since the last review, reconcile diagrams with code, and produce a pack that describes a state the system was in at some point. Regulators accept this because the alternative is impossible with the tools most organisations have. The result is a cycle where the evidence is always a little behind the system, and nobody claims otherwise.

What regulators actually want is lineage. They want to see how a requirement became a control, how that control became a design decision, and how that design decision became a line of production configuration. And they want evidence that the control applies to the system as it is today, not as it was six months ago when the last pack was assembled.

Financial services

Trade lifecycle lineage: from order capture through execution, clearing and settlement, with every stage connected to the controls that apply to it. When a regulator asks who saw what data at which point, the answer is a traversal of the model, not a spreadsheet assembled from four systems.

Insurance

Policy administration audit trail: the path from quote to bind to endorsement to claim, with data residency, reinsurance treaty application and reserving controls attached to the specific architectural components that enforce them. Reconciliation across policy, claims and finance becomes a structural question rather than a yearly reconciliation exercise.

Healthcare

PHI boundary documentation: the explicit architectural edges at which protected health information enters, leaves or is transformed, with the controls that apply at each edge attached to the edge itself. Data protection impact assessments draw on the model directly, so reviewers see current boundaries, not last quarter's diagram.

Pharmaceuticals

GxP validated-system lineage: validated systems, their validation status, and the chain from clinical trial protocol through data capture, review and archival, captured as a graph rather than a binder. When a system changes, the validation impact is visible from the model before a single document is rewritten.
