Phase C - Information Systems Architectures

TOGAF Phase C - Information Systems Architectures focuses on the development of information systems architecture, which is essential for aligning IT strategy with business goals. This phase is part of the broader Architecture Development Method (ADM) framework in TOGAF (The Open Group Architecture Framework).

This phase is primarily concerned with:

• Developing the Data Architecture:
  • Identifying and defining the structure of an organization’s data assets.
  • Creating models that represent the data lifecycle, storage, and relationships.
• Developing the Application Architecture:
  • Outlining the application landscape, including the interaction between applications and their role in supporting business processes.
  • Defining the major applications and their interrelationships, as well as the technologies and platforms to be used.
• Ensuring cohesive integration:
  • Ensuring that both data and application architectures are aligned with the business architecture and enterprise goals.
  • Developing a comprehensive view that supports effective governance and management of IT resources.
• Utilizing models and frameworks:
  • Employing various modeling techniques to visualize and communicate the architectures effectively, such as UML, BPMN, and others.
• Collaboration among stakeholders:
  • Engaging with various stakeholders to validate and iterate architecture designs, ensuring that they meet business requirements and constraints.

This phase results in identified information systems that are strategically aligned with the organization’s overall architecture vision, facilitating improved decision-making and operational efficiencies.
