Specialty of Industrial Engineers - Efficiency

Eficiency is the special focus of industrial engineers.
Industrial engineers focus on human efficiency as well as efficiency of production equipment, production processes, work systems, products, and business processes.

Among effectiveness and efficiency, efficiency is the focus area of industrial engineers.

Industrial engineers take an effective system as an input and make it more efficienty with principles and tools of efficiency at their disposal.

This idea can be illustrated with value engineering as an example. Value engineers reduce the cost of a product designed and developed by engineers who specialize in inventing, designing and developing the prototypes as well as production models. Industrial engineers do not focus on new product design. But once the new product department comes out the with a working product, value engineers work on it to reduce its cost. value enhancement or cost reduction is the focus area of industrial engineers and not new product design.

In business processes also similar things occur. The business specialists may design a working process which is effective and then IEs can make it more efficient.
