Full-cycle Requirements Management for complex engineering systems

Independent requirements management consultant providing full-cycle requirements engineering and Verification & Validation (V&V) support — from stakeholder elicitation and requirements definition through decomposition, allocation, traceability, compliance, change impact analysis, and Entry into Service.

10+ years
Aerospace & major rail
Audit-ready
Traceability & evidence
Large datasets
High-volume requirements

What you get

  • Clear, testable requirements (reduced ambiguity and late change)
  • Structured allocation (system → subsystem → supplier → test)
  • Traceability and compliance evidence that stands up in reviews
  • Baseline control with clear impact analysis and gap visibility
Typical deliverables: requirements specifications, allocation matrices, traceability matrices, V&V mapping, compliance packs, and clear reporting for stakeholders.

Experience that fits safety-critical delivery

Clear structure, controlled change, and evidence-based progress reporting.

Rail infrastructure (UK)

Major programme experience supporting multi-disciplinary design compliance and V&V, including coordination across multiple design organisations and route sections.

  • Large requirements & compliance datasets (150k+ items)
  • Evidence coordination across disciplines and suppliers
  • Approvals support and integration reporting

Aerospace (civil aviation)

Requirements and V&V engineering support on Airbus wing systems and structures, working within regulated development processes.

  • Requirements definition and traceability discipline
  • Verification planning and evidence thinking
  • Quality control and review support

Requirements engineering services

Engage for one stage, or for end-to-end requirements management and V&V support.

Definition & quality

Requirements elicitation, clarification, and creation of testable, unambiguous requirements.

  • Elicitation, workshops, stakeholder alignment
  • Quality rules, review checklist, wording consistency
  • Non-functional and interface requirements support

Allocation & traceability

Decomposition, allocation, and traceability from system intent to subsystem and tests.

  • Decomposition and allocation to owners/suppliers
  • Traceability matrix and coverage reporting
  • Dataset optimisation for usability and reporting

Compliance & evidence

Compliance tracking, evidence gathering, and non-compliance management.

  • Compliance definition and evidence structure
  • Non-compliance mitigation and follow-up
  • Audit-ready evidence packs

Baseline & change control

Baseline management, change impact analysis, and gap reporting (baseline vs built).

  • Baselines, deltas, and controlled updates
  • Change impact analysis and decision support
  • GAP analysis (baseline vs built)

Lifecycle coverage: concept → Entry into Service

A clear line from business intent to verified implementation and commissioning.

1

Business case & scope

Goals, constraints, assumptions, stakeholders.

2

Requirements definition

System requirements, interfaces, non-functionals.

3

Decomposition & allocation

Subsystem/supplier allocation, ownership and flow-down.

4

Compliance & V&V mapping

Acceptance criteria, methods, test links, evidence planning.

5

Verification & reporting

Coverage, gaps, evidence review, issue closure.

6

Commissioning / EIS

Final compliance pack and handover readiness.
