3 Human Factors Defined Human Factors discovers and applies information about human behavior, abilities, limitations, and other characteristics to the design of tools, machines, systems, tasks, jobs, and environments for productive, safe, comfortable, and effective human use (Sanders and McCormick, 1993) Human Factors discovers and applies information about human behavior, abilities, limitations, and other characteristics to the design of tools, machines, systems, tasks, jobs, and environments for productive, safe, comfortable, and effective human use (Sanders and McCormick, 1993) Human Factors IS NOT … Human Factors IS NOT …  Just using checklists and guidelines  Just using oneself as the model for designing things  Just common sense

4 Engineering Psychology: A Discipline at the Crossroads Psychologists Study Humans Engineers Design Machines Engineering Psychology Human-Machine Systems Psychologists study human behavior... Engineers design things... Engineering Psychologists human-centered Engineering Psychologists design human-centered systems

5 Cost of Ignoring Human Factors is Poor Quality! Increased probability of accidents and errors Increased probability of accidents and errors Less spare capacity to deal with emergencies Less spare capacity to deal with emergencies Increased labor turnover Increased labor turnover Lower productive output Lower productive output Increases in lost time Increases in lost time Higher medical costs Higher medical costs Higher material costs Higher material costs Increased absenteeism Increased absenteeism Low quality work Low quality work Injuries, strains Injuries, strains
