This post is the definitive operational manual for Odoo 20 PLM (Product Lifecycle Management) (mrp_plm) and Quality Control (quality, quality_control). It details feature deep-dives, operational UI navigation paths, enterprise workflows, and explicit screenshot placement instructions.
Executive Summary: The 8 Landmark Advancements in Odoo 20 PLM & Quality
Feature Deep-Dives & Screenshot Instructions
1. Apply an Engineering Change Without Forcing a New Version (mrp_plm)
Feature Overview: Previously, approving an Engineering Change Order (ECO) always forced a new BoM version increment (e.g. v1.1 -> v1.2). In Odoo 20, engineers can apply minor revisions directly to the active version of a Bill of Materials without cluttering version history.
Operational Path: PLM ▸ Engineering Change Orders ▸ [Select ECO] ▸ Apply Changes ▸ Select "Apply to Current Version".

2. Unified BoM Change & Cost Difference Report (mrp_plm)
Feature Overview: Inspecting the financial impact of an engineering change previously required separate revision diff and cost structure reports. Odoo 20 unifies component revision diffs and financial cost deltas into a single side-by-side report.
Operational Path: PLM ▸ Engineering Change Orders ▸ [Select ECO] ▸ Smart Button "BoM Changes & Cost Impact".


3. Quality Admin Transfer Validation Bypass (quality_control)
Feature Overview: If a non-blocking quality check was pending on an incoming shipment, warehouse operators were previously blocked from validating the stock transfer. In Odoo 20, Quality Managers (quality.group_quality_manager) can bypass pending checks and validate transfers directly.
Operational Path: Inventory / Barcode ▸ Transfers / Receipts ▸ Select Transfer ▸ [Logged in as Quality Manager] ▸ Click "Validate" ▸ Confirm Admin Override.

4. Set a Failure Location When a Quality Check Fails (quality)
Feature Overview: Quality Control Points now feature dedicated Failure Locations (failure_location_ids). When an inspection check fails, Odoo 20 automatically updates the destination location of the failed stock item to the designated Quarantine bin.
Additionally, after confirmation, no backorder is created for the failed quantity, unlike in previous versions.
Operational Path: Quality ▸ Quality Control Points ▸ [Select Point] ▸ Set "Failure Location" (e.g. WH/Output/Quarantine) ▸ Run Quality Check ▸ Select "Fail".

Enterprise Operational Workflows
Conclusion
Odoo 20 makes engineering change and quality control faster and safer. Engineers no longer have to bump a version number for every small edit, they can see cost and component differences in one report, and failed inspections move stock to quarantine without manual handling.
The main takeaways:
PLM adds version-free minor ECOs, a unified change and cost report, flexible approval matrices with delegation and inline revision diffing.
Quality adds a manager validation bypass, failure location routing to quarantine, IoT-triggered alerts and mobile inspections with worksheets.
Workflows for minor documentation updates and defective goods quarantine give teams a repeatable, step-by-step starting point.
A good way to start is with one of the two workflows described in this post, then expand to approvals, IoT alerts and mobile inspections. Use the screenshot placement notes to build your own training material as you roll each feature out.

quality.group_quality_manager) can bypass pending non-critical quality checks. Log in as a Quality Manager, open the transfer, click Validate and confirm the admin override.failure_location_ids). When an inspection fails, Odoo automatically updates the destination of the failed stock to the designated location, such as WH/Output/Quarantine, so failed items are isolated from active inventory.
