Factory operating control
Control Packaging Supplier Changes Before Routine Production
A supplier change can alter material, dimensions, processing window, artwork, handling and performance even when the item name is unchanged. The factory should approve the proposed specification, risk, representative samples, line trial, quality evidence and inventory transition before normal use.
01 · Buyer or factory inputs
Information the decision needs
- Current approved item and supplier baseline
- Proposed supplier, site, material and process details
- Drawings, artwork, tolerances and declared changes
- Representative sample and trial quantity
- Line, product, warehouse and transport acceptance criteria
- Old-stock, new-stock and rollback plan
02 · Operating objective
What completion should achieve
Introduce the changed packaging without losing specification, traceability, line performance or finished-pack protection.
03 · Required controls
Turn the objective into controlled work
- 01
Open a change record before purchase or routine receipt
- 02
Compare approved and proposed specifications row by row
- 03
Qualify supplier evidence and representative production samples
- 04
Run controlled line, quality, packing and handling trials
- 05
Define first-delivery inspection and enhanced monitoring
- 06
Separate old and new stock and authorize full release or rollback
04 · Factory interfaces
What connects to this decision
- Procurement change to approved specification
- Material characteristic to machine settings
- Artwork and code to market release
- Pack performance to warehouse and distribution
- Supplier lot to customer complaint traceability
05 · Evidence to collect
Records that make review possible
- Approved change request and comparison
- Supplier qualification and sample traceability
- Production-representative trial record
- Finished-pack and handling results
- Release, monitoring or rejection decision
06 · Common failure modes
Do not confuse a pattern with a confirmed cause
1Commercial approval occurs before technical review
2Samples do not represent the proposed production process
3The trial checks one machine but not final pack or transport
4Old and new stock mix before the change is released
07 · Responsibility boundary
Name who confirms each part
| Role | Possible responsibility in this stage |
|---|---|
| Operations owner | Defines the operating condition, assigns the record and confirms that actions fit the production plan. |
| Quality owner | Defines product-status, sampling, release and escalation controls within the factory system. |
| Maintenance owner | Confirms safe technical work, equipment condition, evidence and restart requirements. |
| Supplier / Allot Tech | Reviews the documented interface or symptom and coordinates project-specific questions within the agreed scope. |
08 · Completion criteria
Evidence that the stage can advance
- The change and unchanged characteristics are explicit
- Representative evidence covers the connected line
- Inventory transition and rollback are controlled
- First deliveries receive defined checks
- Final approval has a named authority and effective date
Decision support
Questions operating teams ask
Does a matching drawing prove interchangeability?
No. Material, tolerances, surface, process variation and handling performance may still affect the line and final pack.
Can a supplier change use normal incoming inspection only?
The factory should decide whether additional qualification, trial and first-delivery controls are needed for the actual risk.
