22 Factory Physics Concepts Factory Physics is study of laws governing behavior of manufacturing systems. Both Factory Physics and Six Sigma focus on process variation reduction, and thus are highly complementary. The authors of the book Factory Physics state, Factory Physics is a systematic description of the underlying behavior of manufacturing systems. Understanding it enables managers and engineers to work with the natural tendencies of manufacturing systems to: (1) Identify opportunities for improving existing systems, (2) Design effective new systems, and (3) Make the tradeoffs needed to coordinate policies from disparate areas. In this course, we will see that the manufacturing and healthcare systems are similar in many ways, and the same laws govern the behavior of healthcare systems also. Some specific concepts/tools covered are: 1.Effect of process time variability on performance 2.Sources of variability in process time 3.How variability propagates from one stage to the next 4.Pooling of resources to reduce effect of variability Reference: Wallace J. Hopp and Mark L. Spearman, Factory Physics, Irwin McGraw-Hill, 2001 22
