Final answer:
Poor design between systems and humans can lead to tragic consequences, as seen in the Three Mile Island nuclear accident. Involving human factor professionals and developing ergonomic design standards can help improve design.
Step-by-step explanation:
Poor design between systems and humans can greatly increase risk, sometimes with tragic consequences. One example of this is the Three Mile Island nuclear accident which occurred due to poor design in the control-center workstations. This accident led to the development of regulations and principles of best design, such as increased operator training and additional instrumentation in nuclear facilities. To improve design, it is important to involve human factor professionals from the beginning of a project and develop standards related to ergonomic design.
