Quality, safety and effectiveness must be built into the product. This requires careful attention to a number of factors such as the selection of quality materials/components, product and process design, control of processes, in-process control, and end-product testing. Due to the complexity of the drug products, routine end-product testing alone is not sufficient due to several reasons. Furthermore, quality cannot be tested into the finished drug product but rather be built in the manufacturing processes and these processes should be controlled in order that the finished product meets all quality specifications. A careful design and validation of systems and process controls can establish a high degree of confidence that all lots or batches produced will meet their intended specifications.The Validation Master Plan should be a summary document and should therefore be brief, concise and clear. It should not repeat information documented elsewhere but should refer to existing documents such as policy documents, SOP's and validation protocols and reports. The validation master plan should provide an overview of entire validation operation, its organizational structure & its content.
