About
The BP2S (EA Rules) mind map template provides a structured reference for Enterprise Architecture (EA) rules, principles, and PR rules used in BP2S (BNP Paribas Securities Services). It covers 278 nodes across six major branches: CARTOGRAPHY, BP2S-GuideRules.ppt, EA RULES, PRINCIPLES, PR RULES, and AT-Rules. The EA RULES branch includes 13 rules such as EAR-01 (Uniqueness of the line of business supported by an information System) and EAR-02 (Position of an information System), each linked to principles like Consistency & Subsidiarity and Interoperability. The PR RULES branch details 22 rules including PR-01 (Consider end to end processes) and PR-02 (Use reference data services & nomenclatures). This template serves as a comprehensive cheat sheet for architects and governance teams to ensure compliance and standardization.
