Industrial engineers must be good at solving problems. They must combine their technical knowledge with a sense of human capabilities and limitations. They should be able to organize many details into a broad view of the total operations and organization of a company. Although much of their work is done independently, industrial engineers must also be able to cooperate with other engineers, technicians, and managers. They must be able to talk with production workers and be willing to understand their concerns. Since they may present their plans in the form of written reports or oral presentations, industrial engineers must have good communication skills.
