A DPP platform should orchestrate trusted data from existing systems, not become another uncontrolled master-data store.

## In brief

- Define one authoritative source for each field.
- Use stable identifiers and versioned mappings.
- Make failures visible, retryable and auditable.

## Assign system responsibilities

Document whether ERP, PIM, PLM, supplier portals or service systems own each value and who approves it for publication.


## Design the interface

Use authenticated APIs or controlled jobs, idempotent updates, pagination, timestamps, units, language codes and explicit schema versions.


## Operate reliably

Monitor jobs, validate payloads, quarantine errors, retry safely and prevent a source-system update from silently changing a published release.


## Frequently asked questions

### Is real-time integration always necessary?

No. Scheduled imports are often sufficient; frequency should follow the business need and change risk.

### What is the most important technical key?

A stable cross-system product or variant identifier, supported by clear mapping rules.
