Introduction
Post-quantum migration can involve hundreds of technical dependencies, multiple suppliers and overlapping change windows. QSD provides programme structures that connect workstreams, risk, architecture decisions, testing, procurement and executive reporting, helping organisations maintain momentum without losing control of dependencies or evidence.
2026 Delivery Context
Post-quantum transition is now recognisable as a multi-year portfolio problem: estate discovery, supplier readiness, PKI and HSM change, protocol testing, procurement, product upgrades and governance will move at different speeds. The EU and NCSC timelines reinforce the need to manage dependencies early rather than compress them into a late migration window. Programme management should therefore use risk-based waves, explicit architecture gates, supplier commitments, test evidence, exception governance and executive metrics. The objective is controlled transition velocity—not maximum technical change in the shortest possible time.
Why It Matters
- The critical path can sit outside the security team—in procurement, application ownership, suppliers or infrastructure change windows.
- Migration waves require clear acceptance criteria, rollback plans and ownership.
- Programme governance must distinguish technical progress from residual business risk.
Our Approach
- Establish programme governance and workstream structure.
- Build integrated plans, dependencies, milestones and decision gates.
- Coordinate risk, architecture, testing, supplier and evidence activities.
- Report progress, blockers and residual risk through an executive-ready cadence.
