What parts led to more efficient production of goods

I would say that technology and machinery has led to more efficient production of goods.  Technology and machinery help produce items faster, which means items can be sold at a higher rate.  New manufacturing processes then take place.  Just think of the Industrial Revolution.  Each time we take a step forward with technology and machinery, production becomes more efficient.  This is not only in production of, but also delivery of goods.

Hope this helps!  :)
