Two inspectors, one doubtful cover

Our UR5e camera trial is waiting on a reference set. One inspector called a line on a polished cover a scratch. Another called it glare. Both signed the same sample sheet. I've kept the cover aside. More accurately, I've stopped it going back into the image trial until we sort the label out. What do you do with a sample that the people making the references cannot agree on?

Give it an undecided label and keep it out of the confirmed good and bad groups; do not let the last signature win.

Done. The two inspectors used different viewing angles. One was looking almost along the cover, which makes every bit of it look dramatic.

Have them use the same agreed inspection conditions on that actual cover, not argue from the pictures.

Would magnification settle it, or could that make them reject marks the normal inspection is meant to accept? I am not sure where you draw the line.

It can help establish whether a mark exists, but the acceptance method still decides whether that mark makes the cover a reject.

Who has the final say when they still disagree?

I would want that person at the viewing session, otherwise the inspectors could just produce another pair of signatures.

Our quality lead joined them. Under the agreed lighting they both saw a faint rub in one place. The bright line in the trial image was elsewhere. We've kept two separate notes against the sample.

Is the rub acceptable under your finish requirement?

Borderline. Quality is asking the product owner. Not putting it into the good set yet, even though the big bright line was a reflection.

Could be a useful difficult example later, once that decision is made.

Later, yes; I would not tune around it while its status is still being debated.

Jasper, did the product owner answer? Our own reference cupboard is filling up with undecided bits.

Hassan, are yours waiting on one decision or lots of unrelated ones?

Different finishes, different owners. A surprisingly efficient way to fill a cupboard.

Product owner accepted the rub under our existing cosmetic method. We have the reason with the sample. I also found that the trial folder contained a sharper crop of this cover labelled deep scratch. Same cover. No wonder this dragged on.

Find the other copies before the next trial, including any training or evaluation folders; changing one label will not change the rest.

Three copies found, all linked to the sample now. Thanks, Beth. I'll keep it in the difficult-example group Sofia suggested, with the signed decision. We still need consistent presentation at the camera.

Does difficult-example mean accepted but hard to image, or still uncertain? Those sound like different groups to me.

I meant accepted but tricky to image. Jasper, perhaps use those words on the folder.
