Statistical design of experiments identifies and removes quality deficiencies

This article presents a user-friendly PC-based software system enabling experimenters to apply statistical design and analysis of experiments in their routine work independently of a statistician. A project by the pharmaceutical industry - the production of child-resistant blister packages - serves to illustrate the advantages.
In various branches of the process industry, efficient planning and analysis of experiments is of paramount importance to quality improvement. Aimless trial-and-error is harmful in more than just one way: on the one hand, valuable resources are blocked by redundant experiments; on the other hand, insufficient experiments may even cause greater damage if they lead to poor process parameter settings.
