Certified Production & Operations Manager (POM) Practice Exam

What is the primary purpose of acceptance sampling?

1. To ensure all products meet design specifications.

2. To determine whether to accept or reject a lot of material based on sample evaluation.

3. To monitor production efficiency over time.

4. To eliminate all defects in production.

The correct answer is: To determine whether to accept or reject a lot of material based on sample evaluation.

Acceptance sampling serves as a crucial quality control technique in production and operations management. Its primary purpose is to assess the quality of a batch or lot of items by inspecting a representative sample. The key aspect is that decisions regarding acceptance or rejection of the entire lot are based on the evaluation of this sample. This approach acknowledges that it may not be feasible or cost-effective to inspect every single item in a large batch, especially when dealing with high volumes or extensive production runs. By utilizing acceptance sampling, organizations can effectively manage quality control without incurring the full costs of 100% inspection. This method allows for a balance between minimizing the risk of accepting defective items (false acceptance) and avoiding the unnecessary rejection of good lots (false rejection). It’s a strategic tool ensuring that products meet acceptable quality levels while optimizing resource use. Other options reflect different aspects of quality management but do not accurately capture the core function of acceptance sampling. For example, ensuring that all products meet design specifications would require much more exhaustive quality control methods than acceptance sampling alone can provide. Monitoring production efficiency pertains to operational metrics rather than specifically targeting product quality assessment. On the other hand, efforts to eliminate all defects in production go beyond mere acceptance sampling and involve comprehensive quality management practices like Total Quality Management (
