Review on Introduction of Validation

The process validation was developed in the 20th century in order to improve the quality of pharmaceutical products. The validation concept has expanded over the last 50 years from analytical methods used to control pharmaceutical substances to analyses of computerized systems. Validation is nowadays successfully used in most areas. The validation of a method aims to ensure the effectiveness of the method from the point of view of some statistical parameters during each stage of production and not only at the end of the process. By validation, scientific evidence is established that a process is capable of consistently delivering quality products. It is also recognized internationally that validation of a product is required in any production process of a new product. This study presents the validation of the proposed method/system/instrument to assess its accuracy, reliability, and applicability. Validation was conducted by comparing the outcomes against established standards and reference data using appropriate statistical and analytical techniques. Key performance metrics, including validity, consistency, and error rates, were evaluated across multiple test conditions. The results demonstrate that the proposed approach meets the predefined validation criteria and shows strong agreement with benchmark methods. These findings confirm the suitability of the method for its intended application and support its use in both research and practical settings.
