Mission Popcorn

How does Design of Experiments (DoE) work?

Design of Experiments (DoE) is an efficient way to develop and improve new processes and products, as well as to minimize costs. To illustrate this complex method, employees of Sartorius Stedim Data Analytics carried out an experiment to produce the optimal popcorn using different settings on microwaves during the “Nacht des Wissens” (English: Night of Knowledge) on January 26, 2019 in Göttingen, Germany. Find out about the results below.
