Final answer:
Acceptance sampling is used before, during, and after production to ensure quality control.
Step-by-step explanation:
The correct answer is: A) I and III only.
Acceptance sampling is a quality control technique used to determine whether a batch or lot of products meets a certain quality standard. It involves inspecting a sample from the production process to make decisions about accepting or rejecting the entire batch.
Acceptance sampling can be used at different stages of production:
- Before production (I): This is called pre-production acceptance sampling. It is used to evaluate the quality of raw materials or components before they are used in the production process. By doing so, any potential issues can be identified and addressed early on.
- During production (II): This is called concurrent acceptance sampling. It is used to monitor the quality of the products being produced in real-time. Samples are taken at regular intervals to ensure that the production process is consistently meeting the desired quality standards.
- After production (III): This is called post-production acceptance sampling. It is used to inspect the final products after they have been produced. This allows for an assessment of whether the entire batch meets the specified quality requirements before it is sent to customers.
Therefore, acceptance sampling can be used both before, during, and after production to ensure quality control.
