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. If specifications are too wide, the risks of inadequate product performance and product failures increase. If specifications are too tight, the costs to ensure conformance increase. 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.  Appropriate product specifications are critical to achieving adequate and reliable product performance.
