    Study Notes

    • Architecture implementation in IT and defense domains uses frameworks like TOGAF, NAF, and DoDAF
    • Implementation includes metamodel development, architecture development methods, standards library, architecture repository and registry, and architecture capability
    • Architecture capability includes skills and governance logic
    • Enterprise and product architecture frameworks established to ensure consistency with enterprise strategy (Sowa and Zachman, 1992)
    • Multiple entities with interrelated life cycles must be considered during architecting
    • Architecture management implements governance directives and manages architecture description
    • Architecture description accomplished through Architecture Conceptualization and Architecture Elaboration (ISO/IEC/IEEE 42010 and 42020)
    • Architecture evaluation determines extent to which architectures meet objectives, stakeholder concerns, and requirements (ISO/IEC/IEEE 42030)
    • Architecture evaluation frameworks like Architecture Tradeoff Analysis Method (ATAM) and Method Framework for Engineering System Architectures (MFESA) allow performing evaluation in three steps: defining objectives, development of evaluation method, and analysis of architecture concepts and properties.
