1. Pressman, R. S., & Maxim, B. R. (2020). Software Engineering: A Practitioner's Approach (9th ed.). McGraw-Hill. In Chapter 16, "Software Quality Assurance," the text distinguishes Quality Control as a series of inspections, reviews, and tests used to ensure each work product meets its requirements, directly linking QC to specific products.
2. International Organization for Standardization. (2015). ISO 9000:2015: Quality management systems — Fundamentals and vocabulary. Section 3.3.7 defines Quality Control as the "part of quality management focused on fulfilling quality requirements." The application of this principle involves checking the outputs (products/services) against the requirements.
3. Galit, A. (2004). Software Quality Assurance: From Theory to Implementation. Pearson/Addison-Wesley. Chapter 1, "The Software Quality Challenge," explains that quality control activities are "focused on the detection of faults in the specific products" (p. 12), reinforcing the product-specific nature of QC.
