#382: Design of Experiments - How and When to Use DOE
Perry Parendo, founder of Perry Solutions, explains how Design of Experiments (DOE) serves as a strategic tool for understanding systems and reducing risk in medical device R&D and manufacturing. He details the practical application of DOE, emphasizing the use of fractional factorial designs to manage 3-7 variables effectively, and warns against common pitfalls like using pass/fail metrics or relying solely on software tutorials without practical training. Parendo advocates for a phased approach—starting with small 'play' experiments, moving to structured DOE, and ending with verification tests—to ensure robust process stability and product performance before validation.
