Choosing Platform Realisations

Choose for the operational purpose

A platform realisation is a proposed arrangement of capabilities supporting defined architectural responsibilities. Suitability depends on the selected services, configuration, operating environment and evidence for the intended use.

Begin with the outcome, existing capabilities and constraints. Several platforms, human processes or partner services may contribute to the same responsibility. Product availability alone does not establish that the complete arrangement works.

Compare proposals using the same questions

Decision concern	Evidence to examine
Purpose and boundaries	Operational intent, users, subjects, expected outcomes, exclusions and material consequences.
Representation and meaning	Source identities, accepted definitions, semantic mappings, versions, provenance and known non-equivalence.
Context and qualification	Required inputs, freshness, quality, omissions and evidence that the resulting understanding supports its intended use.
Authority and human participation	Who may rely, decide and act; delegation limits; what a person reviews and contributes; how changes or revocation are handled.
Execution and outcome	Applicable conditions, actual execution records, failure and recovery behaviour, observed outcomes and review responsibilities.
Integration and portability	Demonstrated interfaces, supported formats, dependency limits, migration effort and retained meaning across boundaries.
Operation and obligations	Ownership, service limits, access paths, processing location, retention, resilience, cost and applicable organisational obligations.
Revision and learning	Version and change controls, impact on consumers, requalification or reacceptance requirements and preserved history.

Make the comparison concrete

For each candidate composition, record which responsibility it addresses, which component or person fulfils it, the supporting evidence and any unresolved condition. Keep documented capability, configured behaviour, observed test results and production evidence distinguishable.

Use representative scenarios to examine normal operation and material exceptions, such as stale information, an ambiguous mapping, revoked access, a changed action or a failed handoff. Define expected behaviour and acceptance criteria before drawing a conclusion.

A comparison can support retaining an existing capability, composing several capabilities, conducting a bounded trial or deferring a decision. Unresolved evidence should remain visible.

Record the decision and its limits

The Architecture of Record (AoR) can record accepted arrangements, applicability, obligations and boundaries. Include the evidence relied upon, assumptions, accountable owners and changes that would trigger review.

Qualification for reliance does not itself authorise execution. A reference mapping does not demonstrate implemented enforcement, compliance or an issued Profile.
