Indeed. Journalistic leeway aside: I work close to manufacturing, and at our scale we measure things in DPPM (Defective Parts Per Million (manufactured)). In my line of work, defect rates in the tens to low hundred DPPM (10 - 100 / 1000000) is noise, high hundreds is cause for attention.
When failures approach the Per Cent-age rate, that's equivalent to ~10k DPPM, and that's daily stand-up territory.
- user_7832 3y agoCould you share in terms of defective parts per day (or hour), how much would that be? Or roughly how many parts were being made daily? (Reason for asking is that this metric could be partially extrapolated to high-quality low-scale manufacturing as well.)
- hef19898 3y agoDPMO lives from large numbers, extrapolaiting it to low scale manufacturing would extend measurement periods to point the KPI becomes useless.
- user_7832 3y agoIt might not be very helpful in many cases, but can still be an "ideal" reference/target especially from the point of view of someone manufacturing at a a small scale.
