1.1-12 Display of Information to Support Planning

The HSI should present information to support users in planning for and coordinating concurrent tasks.

Additional Information:
Providing information that gives advanced notification of plant conditions or the need for action can help users prioritize and plan tasks. It can also reduce the mental workload and improve the utilization of cognitive resources for primary tasks. Examples of HSI features that can provide advanced warnings and indications include: checklists and computer-based aids that allow the user to look ahead at future activities (e.g., computer-based procedures that show upcoming steps); trend and predictor displays; and alarms and displays that provide early warnings of developing conditions. This information should be presented in ways that reduce distraction, since distracting stimuli can impose high demands on attention resources.
