Lean Manufacturing

Principles of lean manufacturing are introduced that provide a systematic process for identifying and eliminating non-value activities (waste) in production processes. Students learn these principles through a series of mini-projects in the mechanical engineering shop, an all-day factory simulation workshop, and tours to local industry.
