Useful Statistical Methods for Defining Product and Process Specifications

Scientists, Design Engineers, and Manufacturing/Process Engineers must develop product and process specifications that ensure that products delivered to customers perform their intended functions over time.

Scientific and engineering theory, knowledge, and principles play an important role in developing specifications, but usually this must be combined with testing and data analysis to verify appropriate specifications.

This webinar covers useful and important statistical methods that assist scientists and engineers in the development of appropriate product and process specifications.

Why you should Attend: The information gained in the webinar will allow you improve your ability to develop appropriate and defensible specifications.

This manages the risks of overly liberal specifications and the costs associated with overly conservative specifications.
