✅ 8.1 Purpose & Objectives


🔹 Purpose of Phase D

🟢 To develop a Target Technology Architecture that supports the:

  • Business Architecture

  • Data & Application Architectures

  • Architecture Vision

💡 Exam Tip: If a question involves technology, it most likely relates to Phase D

🔸 Business-IT Alignment Cascade

  • Phase B: Defines Business Architecture (goals, capabilities)

  • Phase C: Defines Data & Application Architectures to support business

  • Phase D: Defines Technology Architecture to support all the above

✅ This alignment from strategy to systems is known as Business-IT Alignment

🎯 Objectives of Phase D

✅ Objective 1:

  • Develop the Target Technology Architecture

    • Defines technology building blocks (TBBs)

    • Enables delivery of:

      • Business capabilities

      • Data & application services

      • Architecture Vision

    • Aligned with the Statement of Architecture Work and stakeholder concerns

✅ Objective 2:

  • Identify Candidate Roadmap Components based on:

    • Gaps between baseline and target technology architectures

🔁 Objective 2 is consistent across Phases B, C, and D
🔁 Objective 1 is similar across all three but tailored to the domain

🔧 What is the Technology Architecture?

  • Defines the infrastructure, platforms, and tech services needed to support enterprise applications and data

  • Includes:

    • Servers

    • Networks

    • Middleware

    • Cloud platforms

    • APIs

    • Integration tech

🧱 These are called Technology Building Blocks (TBBs) in TOGAF
