Prior to developing a process control plan as part of an overall risk management strategy, process development studies must be completed. The objective of these process development studies is to gain knowledge and understanding about how variation in process parameters explains variation in the product quality characteristics of the product.
The use of DOE methodology provides a means to identify process parameters which impact product quality (critical process parameters) and determine the functional relationship that links the process parameters to those critical quality attributes. Screening designs, such as 2k factorial and D-optimal designs, are used to determine critical process parameters. Response surface designs, such as Central Composite Designs (CCDs) and I-optimal designs, are used to model the functional relationship between those critical process parameters and the critical quality attributes.
This course will begin by presenting a primer on statistical analysis, focusing on the methods required for analysis of designed experiments. It will then present the steps to DOE, while demonstrating valuable risk management tools (Ishikawa and FMEA) which can be use pre and post DOE studies. Next, participants will learn to generate and analyze multiple screening and response surface designs; the participants will leave with an understanding of why and how each are used. Then, the participants will learn how results of the studies can be presented. Lastly, using the results of the studies, the risk management tools will then be updated.
The Global Harmonization Task Force (GHTF) Process Validation Guidance for Medical Device Manufacturers provides guidance on where design of experiments should be applied during process validation; it suggests the use of both screening and response surface designs during Operational Qualification. In addition, DOE should be used during multiple phases of design controls: design and development planning, design verification, design validation, design transfer, and design changes.
In Guidance for Industry Q8 Pharamaceutical Development (as well as the annex to Q8), suggests applying experimental design to demonstrate "...an enhanced knowledge of product performance over a range of...process parameters." Using this "...enhanced, quality by design approach..." leads to greater system understanding. That greater system understanding has two elements: identifying critical process parameters and developing a functional relationship that link those critical process parameters to your critical quality attributes (CQAs). This suggests the use of both screening and response surface designs during pharmaceutical development studies.
The need for DOE in product and process development is not only suggested, but imperative for both medical device and drug manufactures.

Heath Rushing is the cofounder of Adsurgo LLC and co-author of the book Design and Analysis of Experiments by Douglas Montgomery: A Supplement for using JMP. Previously, he was the JMP and Six Sigma training manager at SAS. He led a team of nine technical professionals designing and delivering applied statistics and quality continuing education courses. He created tailored courses, applications, and long-term training plans in quality and statistics across a variety of industries to include biotech, pharmaceutical, medical device, and chemical processing. Mr. Rushing has been an invited speaker on applicability of statistics for national and international conferences. As a Quality Engineer at Amgen, he championed statistical principles in every business unit. He designed and delivered a DOE course that immediately became the company standard required at multiple sites. Additionally, he developed and implemented numerous innovative statistical methods advancing corporate risk management, process capability, and validation acceptance criteria. He won the top teaching award out of 54 instructors in the Air Force Academy math department where he taught several semesters and sections of OR and statistics. Additionally, he taught Operations Research and simulation modeling at the Colorado School of Mines and designs and delivers short courses in statistics, data mining, and simulation modeling for SAS.
