Programme Digital Thread from Requirement to Test Evidence

Traceability is the heart of a defence programme's evidence and the thing every tool promises and none delivers across the boundary to the next tool. Requirements management, model-based systems engineering, test management and document control each hold part of the thread, and the joins are kept in spreadsheets.

The platform does not replace those tools; it models what they hold in one ontology, requirement, function, design element, interface, test case, test run, evidence, and links the records across systems. Verification status is then a query: which requirements at this baseline have no passed test, which tests are affected if this interface changes, which evidence is missing for the customer's acceptance review. Agents can draft the compliance matrix and the review pack from the graph, and a systems engineer checks it.

Programme data is classified and export controlled by default. The model runs on the contractor's own infrastructure, applies the same markings the source systems carry, and gives the customer's review team a view scoped to what they are entitled to see.
