Suppose in an organisation, when we have to evaluate the quality of incoming or outgoing products – “How we do it?” Based on certain quality characteristics – “How we make a decision whether to accept or reject the lot?”
The answer lies behind the concept of “Acceptance sampling”. It is an alternative to 100% inspection. Here, inspection is performed on a lot or batch of parts or products. We can use acceptance sampling to accept or reject a lot based on a representative sample. It plays a major role in the quality control process.
Please keep in note that acceptance sampling doesn’t improve the quality of a process but it helps to control quality to a great extent. It helps in decision making whether to accept or reject lots.
Some of the benefits are
Which method to use: Attribute sampling plan or Variable sampling plan?
It depends on which types of data we are dealing with. If it is an attribute type of data, we will go for Attribute sampling plan and if it is a variable data, we will go for Variable sampling plan.
Since we have discussed the basic concepts of acceptance sampling. Now, I would like to move a little forward and discuss the risks involved in acceptance sampling.
You must be thinking, “Why risks are involved?” Let me remind you, we are not doing 100% inspection – we are taking a sample from a lot for inspection.
There are two types of risks involved while doing it –
