Objectives
Our DoE course offers a clear, hands-on introduction to planning and analyzing experiments using Minitab. The course features four case studies presented in a completely click-through manner. All examples are set in a pharmaceutical context.
DoE theory is covered at a practical level to ensure participants understand the concepts and can accurately interpret software outputs, ultimately leading to correct conclusions.
• Day 1: Focuses on the planning stage of DoE
• Day 2: Focuses on the analysis of DoE results
The course covers a broad range of classical and modern DoE designs, including full and fractional factorial, Plackett-Burman, central composite (RSM), D-optimal and mixture designs.
Background
In the planning step, a minimal number of experiments is selected to representatively cover the experimental space. In the analysis step, a multivariate empirical model is fitted to the measurements to describe the relationship between process parameters and quality attributes of interest. This model is then used to predict product quality with the desired level of certainty and to establish operational ranges that ensure compliance with specification limits.
The importance of the DoE methodology in the pharmaceutical development is further emphasized by various regulatory guidelines, including the Quality ICH Guidelines (Q8, Q11, and the newer Q14) and, more recently, the European Pharmacopoeia (Supplement 11.7).
