A textile mill in Surat polishes the back side of fabric rolls to a mirror finish although customers never see or specify this finish. Which of the eight wastes is this?
This is over-processing waste, because effort and cost are spent on a finish the customer neither needs nor will pay for. Over-processing means performing more work or higher quality than the customer's requirement specifies, so it adds cost without adding value.
- AOver-processingCorrect
- BMotion
- COverproduction
- DTransportation
Explanation
Over-processing is doing more work, higher precision or quality than the customer requires or will pay for. Here the finish adds cost without value. Overproduction concerns quantity, not the extent of processing.
