Focus lines · introduced in full on this site
DPP implementation
EU Digital Product Passport delivery: establish regulatory scope and data gaps first, then design product master data and traceability, implement the platform on open-dpp, and take a pilot product line all the way to publishing.
- Compliance gap assessment, delivered as a prioritised list
- Passport data model, identifier scheme and supplier collaboration flow
- Platform implementation on open-dpp, from pilot to go-live
WorkGraph - task graph
Turns a project from documents plus boards into a single task graph: dependencies, resources and progress all land on one graph, and the whole stack can run on your own machines.
- Dependencies form a graph; progress is computed on write, never aggregated on read
- Start from templates - the main feature line already runs on real projects
- One compose file brings up the stack; data and files stay inside your network
