In which pat & the ADM cycle &e building blocks evolved using a common platform of steps?

The Preliminary Phase and Phase A (Architecture Vision) focus on preparing the enterprise for architecture work and establishing the vision, not detailed building block evolution.

Phases B (Business Architecture), C (Information Systems Architectures), and D (Technology Architecture) of the ADM cycle are where the core architectural building blocks are defined and evolved. These phases follow a common pattern of steps, including developing baseline architecture, target architecture, and performing gap analysis for their respective domains.

Phases E (Opportunities & Solutions) and F (Migration Planning) focus on identifying solutions and planning the implementation of the architecture, rather than the initial evolution of building blocks.

Phases G (Implementation Governance) and H (Architecture Change Management) focus on overseeing implementation and managing change, respectively, not the primary evolution of building blocks.
