Operational Analysis - Overview
▌ Focuses on analysing the needs and goals, expected missions &
activities
▌ Is expected to ensure good adequacy of System definition with regards
to its real operational use – and define IVVQ conditions
▌ Outputs:
Needs, in terms of Actors/Users
Operational capabilities and activities
Operational use scenarios (dimensioning parameters, operational constraints, including safety, security, system life cycle)

System Need Analysis - Overview
▌ Define how the system can satisfy the former operational needs:
System functions to be supported & related exchanges
Non functional constraints (safety, security,…)
Performances allocates to system functional chains
Role sharing and interactions between the Operators and the System
▌ Checks for feasibility (including cost, schedule and technology readiness)
of customer requirements
▌ Outputs: System Functional Analysis description
Interoperability and interaction with the users and external systems (functions, exchanges, plus non fonctional constraints), and system requirements

Logical Architecture - Overview
▌ Intends to identify the system components, their contents, relationship
and properties, excluding implementation or technical/technological
issues.
This constitutes the system logical architecture
▌ All major non functional constraints are taken into account so as to find
the best compromise between them
▌ Output: Selected Logical Architecture
Components and Interfaces definition, including formalisation of all viewpoints and the way they are taken into account in the components design.
Links with requirements and Operational scenarios are also produced

Physical Architecture - Overview
▌ Intends to identify the system components, their contents, relationship
and properties, including implementation or technical/technological
issues.
▌ Introduces rationalisation, architectural patterns, new technical services,
and components
▌ Makes the Logical Architecture evolve according to implementation,
technical and technological constraints and choices (at this level of
engineering)
▌ The same ‘Viewpoints-driven’ method as for logical architecture used
▌ Output: Physical Architecture
