Industrial engineers, for example, must have a passion for improvement. Industrial engineering is about optimizing processes and finding ways to eliminate practices that do not add value. As an industrial engineer, you must be able to think critically and be resourceful. It takes persistence and patience to determine the best way to solve a problem. The answer to many technical problems comes only after thorough investigation, trial and error. Industrial engineers must continually verify and validate many different models and simulations to improve a system. A good industrial engineer is able to use their passion for improvement to continually question how to make things happen
