# DPP implementation: an 8-step readiness plan

> From legal scoping to scaled rollout — the sequence that works.

## Key takeaways

- Start with scope and data ownership, not software.

- Supplier data is usually the longest lead-time item.

- Pilot with real missing-data cases before you scale.

## The eight steps

- 1. Confirm legal scope — product families, markets, applicable laws and dates.

- 2. Assign the responsible operator, programme owner and data owners.

- 3. Map existing data in ERP, PLM, PIM, LCA tools and supplier files.

- 4. Run a field-level gap assessment and plan supplier collection.

- 5. Decide granularity, identifiers, carriers and access policies.

- 6. Pilot representative products, including missing-data cases.

- 7. Test scans, permissions, updates, exports and lifecycle handovers.

- 8. Scale with monitoring, evidence retention and exit/continuity provisions.

## Typical timeline

| Phase | Duration (indicative) |

| --- | --- |

| Scoping & gap analysis | 1–3 months |

| Supplier data collection | 3–12 months |

| Pilot | 1–3 months |

| Rollout | 3–9 months |

## Lesson from batteries

Volvo and Circulor's EX90 battery passport took more than five years of development — publishing a passport is quick; establishing the supply-chain visibility behind it is not.
