Designed Experiments for Medical Devices

In this one-of-a-kind workshop, learn how to apply DOE to medical device testing and manufacturing problems. We welcome scientists, engineers, and technical professionals working in this field. The design of experiments topics range from modernized factorial and fractional-factorial designs for screening and characterization, to state-of-the-art response surface methods for process optimization. Throughout this course you will explore cases that come directly from the medical device industry!

A 10% discounted Early Bird rate applies to registrations made 6 weeks prior to the workshop date. A $200/person discount is applied for 2 or more attendees registering together. Price includes a $95 fee for workshop materials which is subject to state and local taxes.

Designed Experiments for Medical Devices


Designed Experiments for Medical Devices (DEMD), $1295

Customized DOE applications for the medical device industry (developed due to popular demand!)

Optimize your Product or Process

In this one-of-a-kind workshop, learn how to apply DOE to medical device problems. We welcome scientists, engineers, and technical professionals working in this field, as well as organizations and institutions that devote the majority of their efforts to research, development, technology transfer, or commercialization of medical devices. Throughout this course you will explore cases that come directly from this industry!

During a fast-paced two days explore the use of fractional factorial designs for the screening and characterization of products or processes. Also see how to achieve top performance via response surface designs and multiple response optimization.  Practice applying all of these DOE tools while working through cases involving medical device design, pacemaker lead stress testing, and typical processes that may be used in the testing or production of these devices such as seal strength, soldering, dimensional analysis, and more.

Stat-Ease's highly experienced DOE experts will provide you with individualized guidance and support after class to help you get started on your next project—at no extra cost!

Two optional fun and easy-to-read texts, DOE Simplified and RSM Simplified, authored by Mark Anderson and Pat Whitcomb, provide supplemental background reading for all DOE topics covered.

Simulations Provide Practice

Use Design-Expert® software to practice designing and analyzing experiments throughout the workshop. The software provides easy-to-use graphical tools to find key variables and view results. You will be given USB flash drive containing all simulation and data files used in class, as well as a free fully-functional, but time-limited, copy of Design-Expert software for use during and after class.

"Nice mix of computer time and lecture with good real-life examples."

Math skills, knowledge of basic statistics, and exposure to simple comparative experiments (e.g. two-sample t-test) are recommended. As a prerequisite, take the online PreDOE course first (a $95 value you get for free! It takes 2-3 hours to complete. You can work at your own pace). Access the PreDOE here.

Before attending class, please download a trial of DX11 (if you do not already have access to it) and work through the General Multilevel-Categoric One-Factor tutorial.
