Single source of truth
A consistent requirements dataset with clear identifiers, ownership and status rules.
- Stable IDs and naming conventions
- Status definitions and review gates
- Evidence linkage rules
Lifecycle Coverage • Traceability • Compliance • V&V
Concept → Entry into Service
Requirements only work if they remain consistent across the entire delivery chain. This page shows how I structure requirements, traceability, baselines, compliance evidence and V&V mapping from early scope through commissioning and Entry into Service.
Typical lifecycle problems
- Requirements drift between stages and suppliers
- No reliable traceability (coverage unknown)
- Baselines are unclear or constantly moving
- Compliance claims lack structured evidence
Outcome: a controlled dataset, clear responsibilities, and evidence-based progress.
Lifecycle stages
A structured chain from intent to verified implementation.
1
Business case & scope
Goals, constraints, assumptions, stakeholders, boundaries.
2
Requirements definition
System requirements, interfaces, non-functionals, acceptance intent.
3
Decomposition & allocation
Flow-down to subsystems and suppliers, ownership and responsibility.
4
Baselines & change control
Freeze points, controlled updates, impact analysis and delta reporting.
5
Compliance & evidence structure
Claims tracking, evidence mapping, non-compliance management.
6
V&V mapping
Verification methods, acceptance criteria, test linkage and coverage.
7
Verification & reporting
Coverage, gaps, evidence quality checks, closure tracking.
8
Commissioning / EIS
Final evidence pack, handover readiness, closure of open findings.
What stays stable across the lifecycle
The backbone that prevents late surprises.
Traceability and coverage
Trace links that provide real coverage reporting, not decorative matrices.
- System → subsystem → supplier → test
- Coverage views and gap tracking
- Quality checks (missing links / duplicates)
Baseline control
Baselines provide delivery stability. Changes are controlled, measured, and explained.
- Release structure and freeze points
- Change impact analysis
- Delta reporting (what changed, why, and effect)
Compliance evidence
Claims must map to evidence. Evidence must be reviewable.
- Evidence structure and filing logic
- Non-compliance tracking and mitigation
- Audit-ready packs
