Sample interview questions: Can you discuss a time when you used human factors principles to optimize the design of a control room in a chemical plant?
Sample answer:
-
Task Analysis: Conducted a detailed task analysis to understand the operators’ responsibilities, information needs, and decision-making processes. This involved observing operators in their daily tasks, interviewing them, and gathering data on their workload, stress levels, and error rates.
-
Workstation Design: Designed the control room layout and workstation configuration to optimize operators’ reach, visibility, and access to controls and displays. This included arranging panels, screens, and controls in a logical and intuitive manner, minimizing the need for excessive bending, stretching, or awkward postures.
-
Human-Machine Interface (HMI) Design: Developed the HMI to ensure clear and effective communication between operators and the control system. This involved designing user-friendly interfaces with intuitive graphics, easy-to-understand symbols, and consistent color-coding. The HMI was also designed to minimize the risk of misinterpretations, errors, and accidents.
-
Lighting and Acoustics: Considered the impact of lighting and acoustics on operators’ performance and well-being. Designed the control room to provide adequate lighting levels without… Read full answer
