Red Tagging is the “action” part of Module 1: Sort. It’s the visual way to identify items that are taking up space but adding no value to the aluminum rail production.
The Red Tag Strategy
In Japanese, the word for “red” can also mean “dirt.” Red tagging is the process of identifying “dirt” in the factory—items that shouldn’t be there—and moving them to a temporary holding area for evaluation.
1. Establish the “Target” Areas
In an aluminum facility, your team should hunt for:
Excess Inventory: Bundles of rails from old projects or over-ordered extrusions.
Damaged Material: Bent or scratched rails that are taking up floor space.
Obsolete Jigs & Dies: Specialized tools for rail models that are no longer produced.
Broken Equipment: Old welding tips, worn saw blades, or leaking hydraulic hoses.
2. Set Your Red Tag Criteria
Before the team starts, define what gets a tag. A common rule is the “Next Month” rule: If it won’t be used for a production order in the next 30 days, tag it.
3. Create the “Red Tag Holding Area”
Designate a visible, taped-off zone on the shop floor where tagged items are moved.
Local Area: For items tagged at a specific workstation.
Central Area: For larger equipment or items that have sat in the local area for more than a week without being claimed
4. The Evaluation Process
Don’t throw things away immediately. Once an item is in the holding area, it undergoes a review (usually every 1–4 weeks) to decide its fate:
Keep: Move it back if it’s needed.
Relocate: Store it in a secondary warehouse if it’s “seldom used but necessary”.
Recycle/Scrap: Send aluminum offcuts and damaged rails to the recycler to reclaim material costs.
Sell/Donate: For tools or furniture that still have value but aren’t needed.
The “Fun” Rule: Cross-Department Tagging
To avoid sentimental attachments (“I might need this old jig someday!”), have the Welding Team tag the Cutting Area and vice versa. A “fresh eye” sees clutter that the daily operator has become “blind” to
