Module 4Slide 2 of 23 WHO - EDM Validation Objectives l To review the definition and types of validation l To understand the requirements for documentation and key stages in the process of validation l To consider models for process validation

Module 4Slide 3 of 23 WHO - EDM Validation Definition l Validation is the documented act of proving that any procedure, process, equipment, material, activity or system actually leads to the expected result

Module 4Slide 4 of 23 WHO - EDM Validation Essential Part of GMP l Predetermined protocols l Written reports l Processes and procedures l Periodic revalidation l Specific attention: ä processing ä testing ä cleaning

Module 4Slide 5 of 23 WHO - EDM Annex 6 Validation WHO References l Good manufacturing practices: guidelines on the validation of manufacturing processes l Validation of analytical procedures used in the examination of pharmaceutical materials
