Validation means making sure every step in a manufacturing process is planned properly and carried out exactly as intended, with clear documentation. It is an essential part of CGMP because it helps guarantee the quality and safety of the final product. Validation and quality assurance always support each other to maintain consistent product standards. In this article, we explain what validation is and why it is important. We discuss different types of validation, including process, equipment, cleaning, and analytical method validation. When each step of production is validated, we can trust that the final product will meet high-quality requirements. Process validation focuses on checking each stage of manufacturing to ensure it works correctly. Since different dosage forms are produced in different ways, each one needs its own specific validation method. The purpose of this review is to give a clear and detailed overview of validation with special emphasis on its role in maintaining product quality.
