The Forgotten Disposition: Why You Should Be Using “Use for Non-Production Purposes”
When a part or product fails inspection during standard manufacturing or quality control, most organizations fall back on a familiar short-list of standard dispositions:
- Scrap
- Rework
- Use As-Is
- No Defect Found
- Return to Vendor (RTV)
While these traditional options cover basic material control, relying only on them creates a massive blind spot in your Quality Management System (QMS).
There is a powerful, highly useful disposition that often gets left off the dropdown menu entirely: “Use for Non-Production Purpose.”
By failing to formalize this option, organizations unintentionally restrict their operational flexibility; or worse, drive employees toward informal workarounds that create real compliance and traceability risks.
Why “Non-Production Use” is a Game Changer
Material that fails a tight production tolerance or cosmetic spec doesn’t automatically lose all value. In fact, non-conforming parts can often serve critical operational needs elsewhere in the business without compromising product quality.
Here are a few common ways non-production dispositions add immediate value:
- Golden Units & Boundary Samples: Non-conforming parts make excellent physical training aids, visual control examples, or “go/no-go” boundary samples to train operators and inspectors on acceptable vs. unacceptable defects.
- Engineering & R&D Testing: Development teams frequently need physical material for destructive testing, fixture fitting, tool design, or stress testing where tight production tolerances aren’t required.
- Sales & Marketing Showcases: Sales representatives, trade show organizers, and demonstration teams often need real physical models to present to prospects. Using non-conforming components for display units saves prime inventory.
The Risk of Leaving It Off the Menu
What happens when an engineering or training team needs a part for testing, but your QMS only allows for Scrap, Rework, Use As-Is, or Return to Vendor?
People find a workaround.
If a process is too rigid, well-meaning employees will simply “borrow” scrap parts out of a bin, bypass inventory logging, or mark an item as “Use As-Is” just to move it across the building.
These informal workarounds lead to serious risks:
- Contamination of Production Stock: Unmarked parts floating around for “testing” can easily wind up back on the shop floor or shipped to a customer by mistake.
- Inaccurate Scrap Data: Scrapping functional material that is actually being used for engineering tests skews your cost-of-quality data and inventory accuracy.
- Audit Non-Conformances: Auditors look closely at material control and segregation. Unlabeled, untracked non-production parts sitting in an engineering bay are a major red flag during an ISO 9001, AS9100, or ISO 13485 audit.
How to Properly Implement “Use for Non-Production Purposes”
Unlocking this disposition doesn’t mean creating a free-for-all. To maintain full compliance, your non-production disposition process must include three key safeguards:
- Mandatory Physical Identification: Any part dispositioned for non-production use must be clearly and indelibly marked using permanent tags, color-coded paint, or physical labels stating: “NOT FOR PRODUCTION USE” or “FOR REFERENCE/TESTING ONLY.”
- Digital & Physical Inventory Isolation: The material must be transacted out of production inventory and moved into a dedicated, controlled location (such as an Engineering or Training location in your ERP/WMS) to prevent accidental use in end products.
- Clear Ownership and Lifecycle Tracking: Treat non-production parts as controlled assets. Define who owns the part, what it is being used for, and set an expiration date for when it should ultimately be scrapped.
Build Flexibility Without Sacrificing Control
Quality management isn’t just about enforcing rules, it’s about designing clear, controlled pathways that enable your business to run smoothly. Adding “Use for Non-Production Purpose” to your material review board (MRB) toolkit eliminates unnecessary waste, supports internal teams, and keeps informal workarounds off your shop floor.
