It is obvious that installation effectiveness is one of the important factors that influence the
production cost-prize. Other contributing factors are raw materials, utilities, people and work
methods. Raw materials as input can be actual raw materials as well as semi-manufactures (altering
the raw material to create a portion of, but not the final product), from a previous installation but
they have to be exterior to the own installation. It should be clear that the maximization of
installation effectiveness can’t be the one and only goal. The costs of maximizing effectiveness should
not outweigh the benefits.
