Leverage Design of Experiments (DoE) in Early Stability Study Planning

Understanding the Tip: What is DoE in the context of stability studies: Design of Experiments (DoE) is a structured, statistical approach to determine the relationship between input factors and measured responses. In early-stage stability studies, DoE allows scientists to systematically explore how variables such as temperature, humidity, packaging type, and formulation composition affect product stability….

Use Bracketing and Matrixing Effectively in Stability Studies for Product Variants

Understanding the Tip: What are bracketing and matrixing: Bracketing and matrixing are scientifically justified designs used to reduce the number of stability tests required when dealing with multiple strengths, fill volumes, or packaging sizes of a single product line. Bracketing tests only the extremes (e.g., lowest and highest strengths), while matrixing staggers time point testing…
