1. Why did management initially favor craft-control of production in the making of iron and steel, locomotives, firearms, bicycles, farm-equipment, machine-tools, castings, and other metal goods? Specifically: What cost savings and other advantages did this system offer employers in the early years of industrilaization (roughly 1870 - 1900) ?

2. Why did management eventually oppose craft control? What disadvantages of the system prompted factory owners to abolish inside contracting and break union contracts with growing frequency between 1890 and 1910? Notes: Please answer and explain so that I may better understand.
