Because Of Industrial engineering is one of the modern forms of engineering. It is more practical in terms of its application compared to older traditional theoretical forms of engineering like mechanical or electrical engineering. Industrial engineering has applications in all forms of industries and business and hence has a much better appeal. Examples of focus areas of industrial engineering are Operations research, Quality, Reliability, Simulation, Energy management, etc. You could apply techniques from industrial engineering to plant layout to resource planning to determining control limits in any process. Industrial engineering helps you make better business decisions and gives other forms of engineering principles a more practical and scientific basis.
