Course Overview

Course in a Nutshell

This course brings together important concepts that allow engineering and operations organizations to understand design of experiments approaches,capabilities, and terminology. We will explain basic statistical concepts and show how they can be used to optimize both the product’s design and its manufacturing process.

The course covers brainstorming, Ishikawa diagrams, mind-mapping, quality assurance databases, and other approaches for identifying potential key performance parameters, and then structures an organized approach for systematically and quantitatively determining which of these have significant impacts. The course utilizes real-life case studies to help you understand these technologies. At the end of the course, you will have a basic understanding of design of experiments tools, technologies, terminology, and capabilities.

An extended two-day version of this course that covers the subject in greater depth and/or includes applications specific to your organization is available.


Learn How To

  • Work together in an effective team environment to resolve product and process optimization challenges.
  • Use the technologies presented in this training to identify key product design and manufacturing process tolerances and control limits.
  • Reduce or eliminate areas of specification non-compliance.
  • Reduce or eliminate scrap and rework causes.
  • Proactively eliminate potential product and process shortfalls before they occur.
Audience / Prerequisites

Aimed At
