The document outlines the process engineers follow to solve problems: 1) Engineers must first identify and describe the problem to be solved, such as identifying the causes of air pollution. 2) Preliminary ideas are generated and rough sketches created to propose potential solutions. 3) The best ideas are refined with scale drawings and calculations to evaluate function, safety, cost and optimization. 4) A final design is decided on and described in detailed working drawings and specifications for manufacturing.
