How does TOGAF recommend handling architectural change?

TOGAF recommends handling architectural change through a structured architecture change management process because this approach ensures that changes are made systematically, with proper consideration of their impacts on the overall architecture. Implementing a structured process allows organizations to evaluate the necessity of changes, assess risks, and manage resources effectively. It ensures that all stakeholders are involved and informed throughout the change process, which enhances collaboration and alignment with business goals.

This structured approach is also vital for maintaining the integrity of the architecture. It provides clear guidelines and procedures to follow, which can help prevent misunderstandings or conflicts that might arise from changes. By documenting the change process and its outcomes, organizations can create a valuable record that can be referenced for future decisions or audits.

In contrast, methods such as ad-hoc decision-making or relying on informal communications can lead to inconsistencies and misalignment across the organization. Likewise, simply waiting for external audits does not proactively address the need for architectural oversight and improvement, leaving organizations vulnerable to missed opportunities or unresolved issues.
