Please help me to sort out this issue by providing the acceptance criteria for visual defects

So you want us, people who do not know anything about your product, what market segment you served, which/what clients you served and what product you manufacture to provide acceptance criteria to you for something very subjective? Doesn't make sense isn't?

Such criterias should normally come from your customer. If not then you need to set one yourself (within your organization) - make sure you do it in consultation with people who are experienced enough to know the market in general as well as what others are doing.

If you already had one, do you have customer complains on this issue? If so, you may need to tighten. If not, why do you need to change it since you mentioned that it does not affect performance.

Rameshs,

Find a couple of people to work with you on this. THey need experience & especially must know what 'good' things should look like and what 'bad things' might look like.

Go through a number of items (eg, stuff already accepted), and get them to talk aloud about what makes each thing/s 'good/OK to accept'. You may need to ask them specific questions to prompt them.

Once you've got that list of criteria, then turn attention to the opposite. Ask them to give you examples / identify 'bad ones' that should not be accepted or that require review.

One good way to do this may be to take pictures (digital cameras make this easy) and use them as illustrative examples (eg, post on wall in inspection place). If/next time something is accepted that shouldn't have been, find out why and add that to the pics/list.

It will take you a little while, but you need to develop these criteria internally. Plus it gets people involved, which is always a good thing.

Rameshs,
You're welcome. Don't ignore customer perception either as Harry points out.

Even if something doesn't affect performance (I don't know what, because I don't know the product, but suppose it was fine scratches on what's normally a smooth surface), if your customers don't like the look, & thus get a perception that what you produce 'isn't good' - even if it works perfectly, they'll not be happy.
