Engagement profile
Keep 11, simplify 6, drop 3 of 20 artefacts.
Tailored artefacts
Business architecture
Organisation/Actor Catalogue
Keepcatalogue, Phase B
Essential for traceability of who owns what across the architecture.
Driver/Goal/Objective Catalogue
Keepcatalogue, Phase B
Always required. Without stated goals, the tailoring itself has no anchor.
Role Catalogue
Keepcatalogue, Phase B
Roles must be explicitly stated so RACI assignments are defensible.
Business Service/Function Catalogue
Keepcatalogue, Phase B
Needed to trace business capabilities through to application and technology layers.
Business Interaction Matrix
Dropmatrix, Phase B
The overhead of a full interaction matrix is not justified at this scale.
Business Footprint Diagram
Simplifydiagram, Phase B
A simplified version gives enough context without full production effort.
Data architecture
Data Entity/Data Component Catalogue
Keepcatalogue, Phase C
Data entities underpin every integration contract. Full catalogue is warranted.
Data Entity/Business Function Matrix
Simplifymatrix, Phase C
Existing data governance can be referenced. A delta view is sufficient.
Conceptual Data Diagram
Simplifydiagram, Phase C
A simplified conceptual diagram helps align stakeholders without full formal notation.
Logical Data Diagram
Keepdiagram, Phase C
The logical data model is the primary contract between data and application architects.
Data Dissemination Diagram
Dropdiagram, Phase C
The cost of a full dissemination diagram is not justified for this profile.
Application architecture
Application Portfolio Catalogue
Keepcatalogue, Phase C
Without an application catalogue, the architecture has no systems inventory.
Interface Catalogue
Keepcatalogue, Phase C
Interface contracts are the primary source of integration risk. Full catalogue required.
Application/Organisation Matrix
Simplifymatrix, Phase C
A simplified mapping of applications to organisational units is sufficient.
Application Communication Diagram
Keepdiagram, Phase C
Application-to-application communication is a primary failure mode. Full diagram required.
Technology architecture
Technology Standards Catalogue
Keepcatalogue, Phase D
Without a standards catalogue, technology choices are ungoverned.
Technology Portfolio Catalogue
Keepcatalogue, Phase D
The technology portfolio underpins licensing, support and lifecycle planning.
Application/Technology Matrix
Simplifymatrix, Phase D
A simplified matrix covering critical applications is sufficient.
Environments and Locations Diagram
Dropdiagram, Phase D
Single-environment engagements do not need this artefact.
Platform Decomposition Diagram
Simplifydiagram, Phase D
Existing platform documentation can be updated. A delta view is sufficient.
Governance justification
This tailoring covers 20 TOGAF Content Framework artefacts for a programme-level, medium-risk engagement with a developing architecture practice. Of these, 11 are retained in full, 6 are simplified to reduce overhead, and 3 are dropped as not cost-effective for the engagement profile. This tailoring should be reviewed by the architecture governance board and recorded as a decision in the Architecture Decision Log.
