7 you. The need for inspection results from excessive variability in the process. The disease is the variability. easing dependence on inspection means you must understand your processes so well that you can predict the quality of their output from upstream activities and measurements. To accomplish this you must have a thorough understanding of the sources of variation in your processes and Pharmaceutical development phases Depending on inspection is like treating a symptom while the disease is killing then work toward reducing the variation. easing dependence on inspection forces you to reduce variability D. eriani Meet MINITAB, Milano 2/04/206 7

8 Pharmaceutical Development Quality Risk Management Pharmaceutical Quality System Development and Manufacture of Drug Substances (chemical/biological entities): in progress - Q8: - Q9: - Q0: - Q: Develop a harmonised pharmaceutical quality system applicable across the lifecycle of the product emphasizing an integrated approach to quality risk management and science I: International onference of armonization D. eriani Meet MINITAB, Milano 2/04/206 8

9 The aim of pharmaceutical development is to design a quality product and its manufacturing process to consistently deliver the intended performance of the product. The information and knowledge gained from pharmaceutical development studies and manufacturing experience provide scientific understanding to support the establishment of the design space, specifications, and manufacturing controls. Information from pharmaceutical development studies can be a basis for quality risk management. It is important to recognize that quality cannot be tested into products, i.e., quality should be built in by design D. eriani Meet MINITAB, Milano 2/04/206 9
