Engineering is the design, analysis, and/or construction of works for practical purposes. The Engineers' Council for Professional Development, also known as ECPD, defines Engineering as: "The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design or to forecast their behavior under specific operating conditions all as respects an intended function, economics of operation and safety to life and property."

One who practices engineering is called an engineer, and those licensed to do so have formal designations such as Professional Engineer , Chartered Engineer or Incorporated Engineer. Engineers use imagination, judgment, and reasoning to apply science, technology, mathematics, and practical experience.

The result is the design, production, and operation of useful objects or processes. The broad discipline of engineering encompasses a range of specialized subdisciplines that focus on the issues associated with developing a specific kind of product, or using a specific type of technology.
