Using Job Characteristics to Inform Interface Design for Industrial Maintenance Procedures

Paper Information

• Subject Area: Human-Computer Interaction (HCI) and Industrial Maintenance
• Keywords: User Experience Design, Industrial Maintenance, Job Characteristics, Interview Study, Digital Procedure Design, Augmented Reality, Industry 4.0, Job Design Theory, Maintenance Culture, Motivation

Research Background and Problem Statement

• Identified Problems or Challenges: Industrial equipment maintenance traditionally relies on paper-based procedures. However, with the advancement of Industry 4.0, organizations aim to transition to digital platforms. There is limited research on how digital technologies impact maintenance work and personnel, particularly on how to digitize procedure documentation to support safe and reliable execution.
• Significance: Maintenance work is critical, especially in safety-critical industries such as mining, manufacturing, and aviation. Non-compliance with procedures by maintenance personnel can lead to severe accidents. Therefore, enhancing their engagement with procedural documentation and their acceptance of digital tools is essential.
• Research Motivation and Related Work: Existing research on maintenance primarily focuses on automation and predictive maintenance technologies, neglecting the behavior, motivation, and work experience of maintenance personnel. The authors aim to comprehensively understand how interface design can improve the operational experience of maintenance personnel by leveraging job design theory, particularly the Job Characteristics Model (JCM).

Solution

• Proposed Solution:

  • Conduct an interview study to understand maintenance personnel's attitudes toward digital devices (e.g., tablets and head-mounted displays).
  • Map the interview findings to the job characteristics defined by JCM (skill variety, task identity, task significance, autonomy, and feedback).
  • Propose design recommendations to support the safe and efficient completion of maintenance tasks.

• Innovative Contributions:

  • Identified eight core factors influencing maintenance personnel's acceptance of digital procedure systems, organized into three categories: Work Identity, Agency, and Community.
  • Introduced job design theory into user interface design, extending HCI research to focus on the psychological states and job satisfaction of maintenance personnel.

• Implementation Steps:

  1. Conduct semi-structured interviews with seven maintenance personnel at an industrial processing plant.
  2. Use thematic analysis to identify eight factors influencing their acceptance of digital technologies.
  3. Organize these factors into a relevant model based on JCM theory and propose specific user interface design recommendations.

Research Outcomes

• Specific Findings:

  • Identified eight core factors influencing maintenance personnel's acceptance of digital devices: task complexity, domain expertise, historical events, efficiency, environment, collaboration, task-based situational awareness, and non-task situational awareness.
  • Developed a theoretical model to guide user interface design, emphasizing support for work identity, autonomy, and community awareness.

• Advantages Over Existing Solutions:

  • Integrated job design theory into user interface design, moving beyond traditional metrics like task completion time to focus on deeper, long-term job satisfaction and performance.
  • Clarified design considerations suitable for complex and hazardous industrial maintenance scenarios, such as noisy environments, task diversity, and collaboration needs.

• Experiment or Evaluation Results:

  • Interviews revealed that maintenance personnel expect digital tools to reduce administrative burdens, enhance task awareness, and improve collaboration opportunities. However, they also expressed concerns about excessive procedural management or reduced autonomy due to new technologies.

• Limitations and Future Directions:

  • Limitations: The study was confined to a single organization and involved only senior maintenance personnel, which may not represent younger or less experienced workers.
  • Future Directions:
    1. Design, implement, and evaluate a user interface prototype based on the study findings to validate recommendations for environmental adaptability.
    2. Further investigate changes in maintenance personnel's work perceptions before and after the introduction of new technologies.
    3. Explore methods for dynamically adapting interfaces to users' task complexity and domain expertise, advancing the integration of HCI and job design theory.
