Acceptance sampling is deployed when inspecting every single item is impractical, destructive, or too costly. It provides a structured plan for evaluating a batch of raw materials or finished goods.
Application of attribute charts when quality characteristics are non-measurable (e.g., go/no-go data).
Statistical Quality Control (SQC), particularly as presented in the works of authors like M. Mahajan, represents the vital intersection of mathematical precision and industrial efficiency. At its core, SQC is the application of statistical methods to monitor and maintain the quality of products and services, ensuring they meet specified standards without the need for exhaustive, 100% inspection.

Before we dissect the file format, it is crucial to understand the authority behind the name. M. Mahajan is a revered author in the Indian academic circuit, particularly for students of mechanical, production, and industrial engineering. His books are published by Danpat Rai & Co. and are well-known for breaking down complex statistical theories into digestible, exam-oriented content.
