Which of the following best summarizes the purpose of Enterprise Architecture?

The fundamental purpose of Enterprise Architecture is to guide effective change by providing a holistic, strategic context for business and technology evolution. It ensures that an organization's transformation efforts are coherent, aligned with strategic goals, and efficiently executed. By creating models and principles that describe the enterprise's current and future states, EA provides a roadmap for navigating complexity and making informed decisions, thereby guiding the process of change in a structured and effective manner.

A. Enterprise Architecture informs and supports decision-making, but its purpose is broader than just taking decisions; it provides the framework for those decisions.
C. "Controlling" is too strong and narrow. EA is more about guiding and governing change through principles and roadmaps rather than direct, rigid control.
D. Enterprise Architecture does not govern stakeholders; it governs the architecture itself while engaging with stakeholders to understand their concerns and gain consensus.
