Demonstrator
Requirement-to-release traceability model
A tool-neutral demonstrator joining requirements, risks, design items, source/configuration, tests, defects, deviations and released versions.
Evidence baseline
What is represented
- Representative requirement, design, repository, test and release identifiers.
- Bidirectional links and exception states represented in a controlled report.
- No customer audit or inspection outcome is claimed.
Constraints
What shaped the engineering model
- Links require competent interpretation; identifier matches can still be wrong.
- Versions across tools must be reconstructable at the release date.
- Approved gaps must remain distinct from accidental omissions.
Responsibility boundary
Who owns which decision
Named ownership prevents a technical work package from silently expanding into product, site, safety, quality or release authority.
Responsibility 1
Axiotech: the engineering method, scoped technical artefacts and stated verification evidence.
Responsibility 2
Customer/OEM: intended use, site constraints, acceptance authority and information supplied.
Responsibility 3
Other competent parties: safety, mechanical, process, quality or infrastructure decisions outside the stated scope.
Lifecycle proof
Decision gates used by the evidence model
The case does not equate activity with acceptance. Each gate has authority, inputs, evidence and unresolved-item visibility.
- G0Scope authorityOutcome, boundaries, roles, assumptions and commercial basis agreed.
- G1Baseline acceptedKnown installed/source state, dependencies, constraints and unknowns recorded.
- G2Design approvedRequirements, interfaces, risks and acceptance evidence ready for implementation.
- G3Release candidateBuild reviewed, verified, versioned and accompanied by defect disposition.
- G4Site acceptanceCommissioning evidence, deviations and release decision recorded.
- G5Handover acceptedSource, configuration, records, recovery and residual risks transferred.
Requirement-to-evidence assurance matrix
A compact proof structure
Public result statements remain deliberately bounded. Project-specific values require approved evidence.
| Need / requirement | Design control | Evidence | Public result status |
|---|---|---|---|
| Coverage visibility | Bidirectional link model | Orphan and status report | Demonstrator report generated |
| Version integrity | Immutable baseline refs | Release reconstruction | Control model demonstrated |
| Approved gaps | Disposition workflow | Exception examples | No customer audit claimed |
Measurable acceptance
What a real engagement would measure
These are acceptance measures, not published customer results.
- Required records without forward/backward links
- Links whose referenced versions cannot be reconstructed
- Open gaps by risk, owner and release disposition
Deliverable manifest
What makes the decision reviewable
- Identification/link model
- Affected-item impact record
- Bidirectional trace report
- Gap/deviation disposition
- Release coverage summary
Limitations
What this evidence does not establish
- Traceability demonstrates relationships and coverage, not correctness by itself.
- Tool integrations and electronic-record controls depend on the chosen environment.
Residual risk
What still requires ownership
- Manual link quality requires sampling and review.
- Emergency changes need disciplined later reconciliation.
Apply the method
Start with a bounded assessment or engineering work package.
Project facts, responsibilities and acceptance measures are confirmed before any outcome is promised.
