Present state of gap

Task analysis and function allocation are an important part of the system design process. They play a major role in task design and in deciding whether a task or function is accomplished by the human, the system or by some combination of humans and systems. On future missions with increased flight duration and autonomy, crewmembers will rely even more on automated systems to provide information that is applicable, accurate, and up-to-date. However, if all tasks are automated, humans can become complacent and lose situation awareness. In addition, increased automation will result in the need for special emphasis on task design and additional training to ensure that the crew can perform the automated tasks in the event of automation failure. Inappropriate function allocation and inadequate design of automated tasks can cause loss of situation awareness or complacency about potential hazards. These situations could ultimately result in system errors, degraded crew performance, and compromised crew and vehicle safety.

Space Human Factors and Habitability currently does not have a set of standard task design methods and tools for dynamic function and resource allocation for tasks, especially when these need to be accomplished dynamically in response to system or schedule changes.

Interim steps for getting to the target

  • Derive mission-specific factors that differentiate future Design Reference Missions from current mission capabilities.

  • Conduct task analysis for long-duration tasks using ground analogs, track mission-specific factors, risk contributing factors, and criteria for ground-based baseline for operational task performance.

  • Identify, develop, and validate task analysis visualization tool for long-duration missions.

  • Develop task aids such as interactive cognitive aids and procedures.

  • Develop and deliver tools, standards, and guidelines to Agency stakeholders/NASA documents (e.g., NASA-STD-3001, HIDH) on the task analysis tools and resource allocation methods.

Research approach

  • Gather ground-based operational task analysis data on tasks from terrestrial analogs

  • Mine spaceflight data related to long duration task analysis and task aids.

  • Validate task analysis and task analysis visualization tools in ground analogs.

  • Develop task aids and procedure selection tools, as well as guidelines for these, for long duration missions.
