This course is intended for employees in development, quality control laboratories, process engineering and quality assurance who currently use DoE or plan to apply it in the future. It is also suitable for GMP auditors, inspectors and validation personnel involved in reviewing DoE studies or regulatory submissions. A basic understanding of statistics is helpful, but no advanced statistical knowledge is required.
Remark: The number of participants is limited to ensure effective hands-on training.
This DoE course offers a clear, hands-on introduction to planning and analyzing experiments using Minitab. It features four pharmaceutical case studies presented in a fully guided, step-by-step format.
DoE theory is covered at a practical level, enabling participants to understand the key concepts, interpret software outputs correctly and draw sound conclusions from experimental data.
- 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
Design of Experiments (DoE) is a key statistical methodology in Quality by Design (QbD). It supports the systematic investigation of process parameters and quality attributes, helps identify critical factors and provides a scientific basis for defining robust operating ranges and Design Spaces in line with regulatory expectations.
