How many are there quality control inspection points? At first inspection stage, we inspect

V: Could you tell me a bit about quality control at the factory?
P: Well, there are four main quality control inspection points. We begin by visiting our suppliers to make sure we are happy with their quality control. Next, we inspect all goods in on arrival at our factory and the third inspection point is during production. And the final stage is chemical analysis of our finished goods.
V: And what do you look for at each of the four inspection points?
P: Well each stage is different. With our suppliers, for instance, we inspect their QC processes and, even more importantly, their factory hygiene. If we’re not happy with their hygiene, we’ll cancel the supply contract. At the goods in stage we make sure that order quantities are correct and the quality is OK. We also check the transport packaging. If the packaging is dam aged, the warehouse shelf-life can be reduced. V: And what quality checks do you run during pro duction?
P: We take samples to check there isn’t too much cooking oil on the snack and that each snack has the minimum amount of flavouring. We also check the size of the snacks and their crisp ness. If the snacks are too oily, they go soft.
V: So that leaves the finished goods. What do you check for at the final QC stage?
P: We check individual bags to make sure that the packet weight is above the acceptable minimum and that the packet is sealed properly. We also check the taste.
V: And how do you do that?
P: Well, we eat them. How else? We also do chemical analysis to check things like fat levels and other information that we have to put on the packets.
