ensure:

• DefiningDefinition performanceof measuresthe roles and responsibilities of key participants (e.g., controllers, traffic managers, maintenance technicians, pilots)
• Determination of whether the proposed allocations present HF risks
  

Scenario Development. HF task and function analyses then support the development of robust scenarios to be used in concept development and demonstration. The task analyses can be used to drive the development of scenarios that help to ensure that a given task sequence is demonstrated from end-to-end in a scenario and that all necessary functionality is present for thereview systemand underanalysis. developmentSuch ina scenario-based approach is important as concepts demonstrated simply through disconnected or partial completion of disparate tasks that do not fully demonstrate the formrelevant ofoperational Measures of Effectiveness/Minimum Operational Performance standards (MOEs/MOPs).

These scenarios are developed by examining the potential uses of the future system and createthe testableroles people will play as operators and maintainers, including not only nominal scenarios but also scenarios highlighting workflows and operational and environmental conditions identified and documented in Critical Task Analysis Reports. 

Verification and Validation (V&V). To minimize “to minimize technical, programmatic, and operational risk”, early HF evaluations are performed to support determination of concept feasibility and analysis of alternative solutions during SASP and CRD phases. During CRD, Consistent with AMS policy Section 4.7, HF involvement during V&V serves to ensure that performance requirements

Determiningare consistent with human performance limitations that are relevant to the system design. Examples include excessive demands on working memory, long  task completion times for data entrycapabilities and impacts on mental workload, vigilance or fatigue
