4-4 Service and Analysis

HF Aspects of Operational Needs. This effort focuses on the specification of changes in the operational concept that encompass an explicit set of use cases and scenarios. This requires participation in meetings discussing use cases, reviewing use case outlines and developing scenarios, and documenting potential human performance risk areas that need to be evaluated during concept demonstration/validation exercises. 

The development of use cases and scenarios also requires completing a task analysis and function allocation analysis, defining the assignment of the roles and responsibilities of key participants (e.g., controllers, traffic managers and maintenance technicians). And it involves identification of the functional and information requirements necessary to support human performance.

The task and function analyses help to ensure that necessary task sequences are demonstrated from end-to-end in the scenarios and that all necessary functionality has been identified for review and analysis as part of concept demonstration and evaluation based on heuristic analyses, prototyping and Human-In-The-Loop studies. Note that this effort may draw upon results from preceding Research for Service Analysis.
