(OPINION) I believe that understanding this work helps people to
understand the difference between Systems engineering and Industrial
engineering. Although closely linked, there are major differences.
The study of Lean is NOT industrial engineering. It is systems
engineering. Although much of what is believed to be Lean certainly
falls within the realm of the industrial engineer, there is an entire
body of study outside traditional industrial engineering which is only
appropriate within the study of Systems engineering. Hence, I
believe, the statement of Jim Womack in 2008 that Lean does not equal
industrial engineering.
