What is Lean Production?
      Lean production means doing more work with fewer 
         resources
      Adaptation of mass production in which work is 
         accomplished in less time, smaller space, with fewer 
         workers and less equipment
      Based on the Toyota Production System
           The term "lean production" was coined by researchers 
            at Massachusetts Institute of Technology

                  Activities in Manufacturing
     1. Actual work - activities that add value to the product
     2. Auxiliary work - activities that support the value-adding 
          activities
     3. Muda (waste) - activities that neither add value nor 
          support the value-adding activities

                  Muda (Waste)
     Taiichi Ohno’s seven forms of waste:
     1.    Production of defective parts
     2.    Production of more parts than needed (overproduction)
     3.    Excessive inventories
     4.    Unnecessary processing steps
     5.    Unnecessary movement of people
     6.    Unnecessary handling of materials
     7.    Workers waiting

                  Keys to Eliminating Waste
     1.    Just-in-time production
     2.    Autonomation (automation with a human touch)
     3.    Worker involvement
