Sample interview questions: Can you discuss a time when you used human factors principles to optimize the design of a transportation vehicle?
Sample answer:
In my experience as a Human Factors Psychologist, I have had the opportunity to apply human factors principles to optimize the design of a transportation vehicle. One specific instance that comes to mind is when I was involved in a project to improve the design of a commercial airline cockpit.
The goal of this project was to enhance the usability and safety of the cockpit for pilots, considering the unique demands and challenges they face during flight operations. To achieve this, I employed a variety of human factors principles and methodologies.
First and foremost, I conducted a comprehensive task analysis to identify the specific tasks and subtasks performed by pilots during different phases of flight. This analysis allowed me to understand the cognitive and physical demands placed on pilots and helped me identify potential areas for improvement in the cockpit design.
Based on the task analysis findings, I then conducted an extensive ergonomic evaluation of the cockpit layout and controls. This involved considering factors such as reach, visibility, and ease of use for various controls and instruments. I paid special attention to the arrangement of critical displays and controls to minimize errors and facilitate efficient information processing.
To further optimize the design, I conducted usability testing sessions with experienced pilots. This involved observing their interactions with the cockpit and gathering their feedback on the design. By incorporating their input, I was able to identify areas where the design could be further refined to better meet their needs and preferences.
In addition to the physical aspects of the cockpit, I also considered the cognitive workload placed on pilots. I analyzed the information flow and the organization of displays and controls to ensure that the cockpit design supported effective decision-making and reduced mental workload. This involved applying principles of information design, such as using clear and concise labels, appropriate color coding, and intuitive mapping of controls to functions.
Throughout the project, I collaborated closely with a multidisciplinary team of engineers, designers, and pilots to ensure that the human factors considerations were integrated into the overall design process. This collaboration facilitated effective communication and ensured that the final design solutions addressed both the fu… Read full answer
