At the center of the model is the Vision — Transparent AI Governance — representing the future state in which AI systems are explainable, auditable, ethically governed, and aligned with enterprise objectives. This vision is realized by the Mission — Enable Trustworthy AI Through Architectural Governance — which defines Ea2Sa’s purpose in establishing the structures, standards, and governance mechanisms necessary to guide AI adoption across the enterprise. The vision is supported and shaped by core values, including: • AI Transparency, ensuring that AI decision logic and outcomes are understandable and observable; • Ethical Data Use, ensuring responsible handling of data across its lifecycle; • RAG-First Information Delivery, ensuring AI outputs are grounded in authoritative, verifiable enterprise knowledge. These values are reinforced through the guiding Principle of Transparency by Design, which mandates that transparency is embedded into AI systems from inception rather than treated as an afterthought. Collectively, these elements define a coherent motivation framework that informs downstream architectural artifacts, including AI Center of Excellence capabilities, governance requirements, solution architectures, and portfolio initiatives.
