Flow 31 — Released Engineering BOM to controlled manufacturing BOM

Translate every exact released design BOM line once into an immutable operation-allocated manufacturing definition, require Product Engineering design approval and a separate Production release, then gate plan creation on that release.

Overview

Inventory meaning

Flow 31 creates definition and review evidence only. Net quantity comes from the released design BOM/output quantity; process scrap derives gross issue evidence. It never edits Engineering, reserves or moves stock, changes custody or creates Assembly work.

Responsible roles

Manufacturing Engineer author → different Product Engineer design reviewer → different Production Manager releaser → Manufacturing Engineer plan author → Auditor read-only

Process

1
Freeze design
Resolve one active variant, released baseline, exact assembly CI/BOM and every approved component line.
Engineering read-only
2
Translate exactly
Cover each source line once and allocate operation, supply, issue mode and process scrap.
Definition only
3
Design review
Different Product Engineer recalculates source and immutable definition fingerprints.
No Production release
4
Production release
Different Production Manager accepts or rejects the approved version.
No stock/custody action
5
Gate planning
Plan copies exact released MBOM materials and routing; stale sources fail closed.
Read-only hand-off
READ ONLY

Role handoff

Manufacturing Engineer author → different Product Engineer design reviewer → different Production Manager releaser → Manufacturing Engineer plan author → Auditor read-only

Detailed steps

1
As Manufacturing Engineer, open Manufacturing → Manufacturing BOM and select one exact active assembly CI from a released baseline. Confirm every released BOM material appears once.
2
Define unique ordered setup/assembly/test operations, allocate each material to one exact operation, declare MAKE/BUY/STOCK and KITTED/POINT_OF_USE/BULK strategy, and enter process scrap. The server derives net and gross quantities.
3
Submit v1. As a different Product Engineer, reject it and confirm the version remains immutable. Create replacement v2 and approve only after exact source and definition fingerprint verification.
4
As a different Production Manager, release approved v2. Confirm Product Engineering cannot perform Production release and Production cannot perform design review.
5
Create a Flow 27 plan from released MBOM v2. Confirm the plan payload has no ad hoc routing; the service copies exact operations and material quantities and rejects changed Engineering source evidence.
6
As Auditor, reconcile one package, two immutable versions, exact per-version line coverage, separate reviews and unchanged Engineering, current_stock, stock_ledger, custody, Assembly and physical identity witnesses.

Manufacturing Engineer

Create the MBOM

Open /manufacturing/mbom

Select the exact released PLM handoff and add manufacturing-only allocation without changing design lines.

Exact field name	Requirement	Sample value A	How to use it
Released Engineering PLM handoff	Select existing	`TRAIN-A-PLM-001 v1`	Select the current exact released handoff.
MBOM title	Required	`TRAIN-A actuator MBOM`	Use a unique controlled title.
Valid from	Required	`2026-10-01`	Start of manufacturing applicability.
Valid to	Required	`2027-09-30`	End of manufacturing applicability.
Process summary	Required	`Kitted mechanical assembly, software load and final inspection.`	Summarise the production translation.
Transformation rationale	Required	`All EBOM lines preserved once; allocations added for routing and issue control.`	Explain how design fidelity is retained.
Issue operation	Select existing	`20 · Mechanical assembly`	Allocate the design line to one exact operation.
Supply strategy	Required	`STOCK`	Choose MAKE, BUY or STOCK as governed.
Issue mode	Required	`KITTED`	Choose the approved issue method.
Process scrap %	Required	`0`	Use evidence-backed process scrap only.
Handling instruction	Required	`Preserve batch identity through assembly genealogy.`	State manufacturing handling controls.

Expected result: Product Engineering approves coverage and a third Production Manager releases the immutable version.

End state

One released MBOM retains exact released-design provenance, one-to-one material coverage, derived issue quantities, governed routing and separate Product Engineering/Production decisions, and becomes the mandatory source for new manufacturing plans without acquiring source or custody authority.
