A Prototype Specification is the executable blueprint produced from a reference architecture and a journey. It is how a decision moves from a pattern to something a client can build, expressed in open standards so it stays portable and vendor-neutral.
From the mission down to a system a client runs. A reference architecture and a journey produce a Prototype Specification, proven in a working model, carried out as a working specification, and built into an executable system.
We keep these distinct so a client always knows what they are looking at.
A reusable pattern for a recurring problem, such as C3. It is not specific to one bank or one journey.
The executable blueprint produced from a reference architecture and a journey. The bridge from pattern to build.
A running proof on Accountable Bank, on synthetic data, with test consumers and never real customers.
The portable artefact a client takes to any vendor, expressed in ISO 20022, BIAN, and recognised control frameworks.
What the client builds and runs from the specification, with their chosen vendor and stack.
Each carries an honest label. A demonstration genuinely runs; a blueprint is designed and specified, not yet demonstrated end to end.
A reference architecture: the Capability, Context, and Consent pattern, stable and reused across journeys. In the Architecture Library.
Our working prototype: four journeys run as interactive demonstrations; Franchise Network is a blueprint. Explore it.
The artefact a client takes to whatever vendor and build they choose. Produced from an engagement, expressed in open standards.
A prototype specification for migrating into a governed target architecture, as a sequence of commercial propositions. See the migration journey.
Provenance, stability, and claim status are separate questions. We never let one stand in for another.
The mechanism genuinely runs in the prototype.
Inputs are generated test fixtures.
Production scale and cutover are described, not executed here.
The boundary. Synthetic data. Test consumers, never real customers. Production-grade controls. Not a production banking system.
Bring the proposition and the journey. We will prove the hard parts in a working model and leave you a specification you own.
