Performance
Hierarchy
 Initially defined in Global ATM
Operational Concept
 Layers represent different views of the
ATM system
 Allows tracing of performance impact
 Changes at lower levels impact next
layer above
 Leads to expectations
 Helps understand and communicate
performance case
Level 1: Political and Socio-Economic
Requirements
Level 2: Expectations - RASP
Level 3: ATM Component
Functionality - RTSP
Level 4: System Requirements (e.g.,
RNP, RCP)
Level 5: Technologies (incl. standards,
specifications)
