Waste Walk (7 Wastes)

What it is and when to use it

Waste hides in plain sight because everyone on the floor has stopped seeing it — the extra trip to fetch a part, the stack of work-in-process waiting between two steps, feels normal because it's always been there. A waste walk is a structured pass through the process, category by category — overproduction, waiting, transport, overprocessing, inventory, motion, defects, and unused talent — that names each instance on the spot instead of relying on memory back in an office. It turns a vague sense that “we could be more efficient” into a specific, countable list ranked by what's actually costing the most.

What goes on the sheet

1. Area/process walked, date, who walked it (ideally cross-functional, not one person alone)
2. One row per waste category (the 7 wastes, plus unused talent as the 8th)
3. Specific instance observed per category: what, where, how often
4. Estimated impact: time, distance, or units affected, with the basis for the estimate noted
5. Photo or sketch evidence for each instance, where practical
6. Priority ranking across all instances found, by estimated impact
7. Owner and next step assigned to the top few, not the entire list

In a business like yours

• Tire shop: timing the walks between rack, bay and parts room shows the minutes lost every shift.
• Restaurant: extra steps between prep, line and walk-in counted during a real service.
• Office: forms printed, signed, scanned and typed again — the same waste, on paper.
