Engineering design refers to the process of designing and developing a product, assembly, or system to be produced and marketed for sale through a production manufacturing process. The fundamental elements of the design process include the establishment of objectives and criteria, synthesis, analysis, construction, testing and evaluation. Because modern technology is so complex, it takes a team of designers and engineers to successfully manufacture a new product. In order to achieve success, the design process must be planned carefully and executed systematically. Specifically, the engineering design process must integrate the many different aspects of designing in such a way that the whole process becomes logical and comprehensible. Engineering design is the use of scientific principles, technical information and imagination in terms of mechanical structure, machine or system to perform pre-specified functions. The fundamental elements of the design process include the establishment of objectives and criteria, synthesis, analysis, construction, testing and evaluation.
