We’re planning to integrate Qualio’s change control module with our PLM system to streamline engineering change orders. The goal is to sync approval workflows so engineering changes in PLM automatically trigger quality change requests in Qualio.
I’m looking for best practices around approval step mapping between the two systems, how to handle rejection scenarios where one system rejects but the other approves, and maintaining audit traceability across both platforms.
Our engineering team uses a 4-step approval workflow in PLM, while quality uses a 6-step process in Qualio. How do others handle workflow alignment when integrating change control systems? What are the gotchas to watch for?
Watch out for approval loops. If both systems trigger updates in each other, you can get infinite approval cycles. We had an incident where PLM approval triggered Qualio update, which triggered PLM notification, which triggered another Qualio update. Implement idempotency checks and state comparison before triggering cross-system updates. Only sync when actual state changes occur, not on every notification.
Rejection handling is tricky because the two systems need to stay in sync. We implemented a “master system” approach where PLM is source of truth for engineering decisions and Qualio is source of truth for quality decisions. If PLM rejects, the change stops in both systems. If Qualio rejects, it creates a quality hold that blocks PLM progression. Clear ownership prevents approval conflicts.
We faced the exact same workflow mismatch issue. Don’t try to force one-to-one step mapping. Instead, define key decision points that exist in both systems - like “Engineering Review”, “Quality Review”, “Final Approval”. Map those decision points across workflows even if the intermediate steps differ. This gives you synchronization points without forcing artificial workflow alignment.
For audit traceability, you need bidirectional links between change records. Each Qualio change should reference the PLM ECO number, and each PLM ECO should link to the Qualio change ID. During audits, inspectors want to trace a change from initiation through implementation across all systems. We maintain a “change correlation table” that maps related records across PLM, Qualio, and our ERP system. Makes audit preparation much easier.
