Architecture Vision in TOGAF ADM (Phase A)

The Architecture Vision phase is the starting point of the architecture development process in the ADM cycle. It sets the foundation by defining what the organization wants to achieve with the architecture effort. Think of it as creating a blueprint of goals and priorities that aligns with the business strategy and meets stakeholder needs.

Key Purpose of the Architecture Vision Phase:

• Define a high-level view of the target architecture.
• Ensure alignment between business goals and IT solutions.
• Secure stakeholder buy-in by addressing their concerns and setting expectations.
• Serve as a roadmap for subsequent phases.

Example in Simple Terms:

• Scenario: A retail company wants to modernize its online shopping experience.
• Inputs:
  • Request for work: Improve customer experience.
  • Stakeholder needs: Faster website, better mobile app, seamless inventory.
  • Existing system: Outdated e-commerce platform.
• Activities:
  • Meet stakeholders, identify concerns (e.g., slow checkout).
  • Define scope: Upgrade website, improve mobile app, add AI-driven recommendations.
  • Develop a vision: A fast, AI-enhanced shopping platform integrated with inventory systems.
• Outputs:
  • Architecture Vision: A diagram showing the target architecture with key goals (e.g., faster checkout times).
  • Stakeholder Map: List of stakeholders like IT, marketing, and customers.
  • Work Statement: Details of the project, timeline, and deliverables.
