4-3 Service Analysis and Strategic Planning
Providing Input to Preliminary Shortfall Report. To characterize shortfalls, relevant human performance deficiencies and critical human performance requirements need to be defined. Preliminary HF inputs could include:
- Reviewing the results of operational analyses of fielded systems, services, facilities and other assets, as well as published research, technology transfers, and related documents from external organizations such as Eurocontrol, MIT Lincoln Labs, MITRE and NASA
- Reviewing the failure reports for operational systems and equipment
- Reviewing failure and safety issues reports (providing indications of performance deficiencies in statements such as "user failed to detect or identify")
- Soliciting feedback from users and customers of relevant FAA services
- Identifying and interviewing Subject Matter Experts (SMEs) regarding human performance issues surrounding the legacy system
-
Qualitatively characterizing shortfalls and documenting where human performance contributes to shortfalls describing human performance limitations, describing human performance limitations that are relevant to the system design (examples include working memory, task completion times for data entry, mental workload, vigilance fatigue, visually tracking multiple simultaneous targets, etc.)
Capturing human performance issues in a shortfall analysis lays the foundation for traceability to preliminary program requirements as well as measures of performance, effectiveness and suitability in the requirements definition process. In an air traffic control example, this could be errors detecting/acquiring/controlling aircraft entering a controller's sector.
