Architecture Roles and Responsibilities
| Author | Rob Campbell | |
|---|---|---|
| Version | Date | Change Description |
| 1.1 | 9 November 2025 | Added SABSA alignment to Service Catalogue |

v2.0 Change Log
| Area | Change | Rationale / Notes |
|---|---|---|
| Scope | Removed tabs: ESA, SSA, OSA role sheets; ESA, SSA and OSA Service Catalogues; Consult ESA Service Catalogue; Consult Services Desc; Tech Security Domains. | Workbook now focuses solely on the Enterprise, Solutions and Operational Architect roles. |
| SFIA 9 | Security roles removed from the role table. Level descriptors corrected (Level 5 = Ensure, advise; Level 6 = Initiate, influence). Skill codes corrected: ARCH = Solution architecture; STPL = Enterprise and business architecture; ITSP = Strategic planning; RLMT = Stakeholder relationship management; TECH = Specialist advice; ITOP = Infrastructure operations. Non-existent codes replaced: SUBD → ARCH; HSIN (as "IT Infrastructure") → IFDN; OPST → ITOP; INAN → USUP; EDUC → ETDL; RESC (as "Resilience") → COPL; TEST (security testing) → NFTS. Reference table rebuilt with SFIA 9 definitions and defined levels; Level Notes column added. | Validated against sfia-online.org (SFIA 9). Corrections applied in place, including all EA, SA and OA role-sheet rows. |
| Through Life | Enterprise Security, Security Solutions and Operational Security Architect columns removed from all three layer tables; EA/SA/OA columns retained unchanged. ESA/SSA/OSA role diagram removed; EA/SA/OA role diagram retained. | Core value-stream content unchanged. |
| EA / SA / OA role sheets | Activity, description and artefact content unchanged. Residual references to ESA/OSA left from the security-role templates corrected to EA/OA; "(with ESA/SSA/OSA)" collaboration notes restated as "(with security architecture)"; duplicated words ("architecture architecture", "operational operational") removed. | Security remains an interfacing function; its roles are no longer modelled in this workbook. |
| Service Catalogues | New EA, SA and OA Service Catalogues (18 services each, IDs EA-nn / SA-nn / OA-nn) in the established catalogue format, with a TOGAF / ArchiMate / ITIL method column replacing SABSA, plus Through Life phase and ODM family columns. | Gives each role an identifiable customer-facing service set, and the ODM framework its anchor. |
| ODM framework | All ODM tabs re-anchored to the EA/SA/OA catalogues. Structure, principles, KRI/KPI/KCI grammar, tier model, dashboard formulas and roadmap layout preserved. Six families redefined for architecture outcomes; 16 ODMs and 2 measurement-plane indicators rewritten; PLA reframed as Performance Level Agreement; contributing indicators, data lineage and all 16 roadmaps rewritten. | Targets and dashboard values remain illustrative pending PLA negotiation. |
About illustrative data
Workbook targets and dashboard values are illustrative pending PLA negotiation. Establish lineage and coverage before treating a measure as PLA-grade.
