Comprehensive and Detailed In-Depth Explanation from Expert in Enterprise Architecture, guiding in TOGAF and ArchiMate:
The Architecture Landscape in TOGAF describes the state of architectures across time and change. It provides a temporal view that allows enterprises to plan, govern, and manage transformation.
The three levels of the Architecture Landscape are:
Baseline Architecture – the current, “as-is” state of the enterprise
Transition Architectures – intermediate, planned states that move the enterprise from Baseline to Target
Target (To-Be) Architecture – the desired future state
Why Option B is correct:
These three levels represent TOGAF’s standard classification of architecture states within the Architecture Landscape.
Why the other options are incorrect:
A. Segment, Enterprise Strategic, and Capability Architectures: These are architecture scopes, not landscape levels.
C. Gaps, Plateaus, and Target Architectures: Gaps and Plateaus are analysis constructs, not landscape levels.
D. Transitional, Complete, and Incremental Architectures: These are not TOGAF-defined landscape levels.
