Reference Architectures

How the T7 model applies to real system architectures. Each pattern shows T-dimension coverage, structural requirements, and common failure modes — without prescribing specific tools or vendors.

RA-001ERP

Enterprise ERP Data Architecture

How T7 applies to enterprise resource planning systems, where multiple modules share a common data foundation but frequently develop divergent data practices.

T-Dimension Coverage

T1Critical

Master data management is the primary Truth mechanism. MDM failures cascade across all ERP modules.

T2High

Document dating, posting periods, and effective-dating of master data are core temporal requirements.

T3High

Customization creates transformation complexity. Business rules embedded in user exits and BAdIs must be inventoried.

T4Medium

Native lineage is limited. Supplement with metadata management tooling for cross-module traceability.

T5Critical

Authorization objects define data access but not data ownership. Ownership must be established organizationally.

T6Medium

ERP platforms are mature. Focus on integration architecture rather than core platform capabilities.

T7High

Role clarity between functional owners and IT is the most common Team failure in ERP environments.

Implementation Patterns

  1. 01Establish a master data governance layer independent of individual modules
  2. 02Version all customization objects in a source control system
  3. 03Define explicit data ownership for each business object type
  4. 04Implement change impact analysis before any schema modification
