In this webinar attendees will learn the key concepts behind Design of Experiments (DOE) and the use of DOE for Process and Product Optimization. Also it will highlight the fractional factorial studies which are useful in the screening phase of experimentation.

Why Should You Attend:

Experimentation is frequently performed using trial and error approaches which are extremely inefficient and rarely lead to optimal solutions. Furthermore, when it’s desired to understand the effect of multiple variables on an outcome (response), “one-factor-at-a-time” trials are often performed. Not only is this approach inefficient, it inhibits the ability to understand and model how multiple variables interact to jointly affect a response. Statistically based Design of Experiments provides a methodology for optimally developing process understanding via experimentation. This webinar focuses on the use of Fractional Factorial Experiments which are invaluable when a large number of factors must be investigated.

Design of Experiments has numerous applications, including:

  • Fast and Efficient Problem Solving (root cause determination)
  • Shortening R&D Efforts
  • Optimizing Product Designs
  • Optimizing Manufacturing Processes
  • Developing Product or Process Specifications
  • Improving Quality and/or Reliability

This webinar will review the key concepts behind Design of Experiments. A strategy for utilizing sequential experiments to most efficiently understand and model a process is presented. The webinar will emphasis fractional factorial studies which are useful in the screening phase of experimentation. Several important techniques in experimental design (such as replication, blocking, and randomization) are introduced. A Case Study involving optimizing a manufacturing process with multiple responses is presented.

Learning Objectives:

Attendees will be able to:

  1. Learn a methodology to perform experiments in an optimal fashion
  2. Utilize very efficient fractional factorial designs to minimize the size of an experiment without sacrificing the ability to estimate important effects
  3. Develop predictive models to describe the effects that variables have on one or more responses
  4. Utilize predictive models to develop optimal solutions

Areas Covered in the Webinar:

This webinar will cover several DOE topics including:

  • Motivation for Structured Experimentation (DOE)
  • DOE Approach / Methodology
  • Fractional Factorial Experimental Designs
