v2.0 Change Log

Area	Change	Rationale / Notes
Scope	Removed tabs: EA, SA and OA role sheets. Security catalogues, Consult ESA Service Catalogue, Consult Services Desc and Tech Security Domains retained unchanged.	Workbook now focuses on the three security architecture roles.
SFIA 9	EA/SA/OA rows replaced by ESA, SSA and OSA; Level Notes column added. Level descriptors corrected (Level 5 = Ensure, advise; Level 6 = Initiate, influence). Codes corrected: ARCH = Solution architecture, STPL = Enterprise and business architecture, RLMT = Stakeholder relationship management, SCAD = Security operations. Non-SFIA-9 codes replaced: IRMG/INRM/REMG → BURM; PROF ("Professionalism") → GOVN/INAS/SCAD by role; INAN → USUP; EDUC/TRMG → ETDL; SECU → SCAD; MONI/OBAS → ITOP; VULN → VUAS; ASMG ("Assurance") → INAS; RESC ("Resilience") → COPL; TEST (security testing) → NFTS; COMP → AUDT; PCOO → PEDP; RLMT ("Real-time Monitoring") → USUP. Reference table rebuilt with SFIA 9 definitions and defined levels.	Validated against sfia-online.org (SFIA 9). Applied in place, including every ESA, SSA and OSA role-sheet row.
Through Life	Enterprise, Solutions and Operational Architect columns removed from all three layer tables; security role columns retained unchanged. EA/SA/OA role diagram removed; ESA/SSA/OSA role diagram retained.	Core value-stream content unchanged.
ESA / SSA / OSA role sheets	Activity, description and artefact content unchanged. ESA sheet given its missing title; stray double spaces removed.
Service Catalogues	Service IDs (ESA-nn / SSA-nn / OSA-nn), Primary Through Life Phases and ODM Family columns added to all three catalogues; ESA catalogue given a scope/consumer line; the stray note in ESA G12 moved to a Notes column.	Aligns the three catalogues and lets every role's services roll up to the ODMs.
ODM framework	Metric set, PLAs, indicators, lineage, dashboard and roadmaps unchanged. Family Map now lists ESA, SSA and OSA services per family; Register "Catalogue Services" uses ESA-nn IDs and adds the directly contributing SSA/OSA services; Overview wording updated to match.	Enhancement only - no targets or definitions changed.
