The document discusses applying lean principles from GM's Global Manufacturing System (GMS) throughout the entire enterprise, including non-manufacturing functions. It outlines how GMS was expanded to offices by using value stream mapping to visualize office processes. The document also discusses standardizing the approach to GMS projects across functions, providing examples of projects in different functions like design, engineering, and finance. Leaders are encouraged to get personally involved in GMS projects to see the benefits and help integrate the process more fully.
