The new SAS ADX Interface provides scientists, engineers, and statisticians with the power to explore, visualize, and model a process through designed experiments. Through the visualization provided by this graphical user interface, you gain valuable insight into the behavior of a process. Scientists convey this knowledge to colleagues and management in a manner that provides the ability to make sound scientific decisions as well as efficient business decisions. This paper describes features of the ADX Interface via a pharmaceutical industry formulation case study where six factors (fluid amount, mixing time, screen size, extruder speed, disk speed, and residence time) are examined using a twolevel factorial experimental design. The scientist’s objectives are to identify factor levels that (1) maximize yield and (2) provide a robust process.
