BusinessCapabiliites

Informs the size, structure, and culture of the capability

Effective operation of the Architecture Capability ensures realization of the Business Vision

Sets targets, KPIs, plans, and budgets for architecture roles

Business Capability drives the need for Architecture Capability Maturity

The method delivers new business solutions

Business need feeds into the method, identifying problems to be addressed

The method refines understanding of business need

The method produces content to be stored in the Repository, classified according to the Enterprise Continuum

The Architecture Capability operates a method

Operational changes update the Enterprise Continuum and Repository

The Enterprise Continuum and Repository inform the business of current state

Learning from business operation creates new business need

The Enterprise Continuum provides structure and

classification for assets in Enterprise Repositories.

Enterprise Repositories provide resources to be

classified within the Enterprise Continuum.

B. Business ArchitectureC. Data/Application ArchitectureD. Technology ArchitectureStep 1: Select Reference Models, Viewpoints, and ToolsStep 2: Develop Baseline Architecture Decription

High-level model of existing building blocks, re-using definitions form Architecture Repository where they are available

Step 3: Develop Target Architecture DescriptionDevelop view of required building blocks through the creation of catalog, matrices, and diagrams of the architecture documentFully document each building blockDocument rationale for building block decisions in architecture documentIdentify the impacted building blocks, checking against a library of building blocks wirhin the Architecture Repository and re-using where appropriateWhere necessary, define new building blocksSelect standards for each building block, re-using as much as possible from reference models selected from the Architecture ContinuumDocument final mapping of the building blocks to the Architecture LandscapeFrom selected building blocks, identify those that might be re-used, and publish as standards of reference models selected from the Architecture Repository

Srep 4: Perform Gap AnalysisIdentify building blocks carried overIdentify eliminated building blocksIdentify new building blocksIdentify gaps and determine the realization approach (e.g. to be developed or to be procured)

Step 5: Define Roadmap ComponentsStep 6: Resolve Impacts across the Architecture LandascapeStep 7: Formal Stakeholder reviewStep 8: Finalize the architectureStep 9: Create the Architecture Definition Document

E. Opportunities and SolutionsAssociate building block gaps with work packages that will address the gaps
