The primary function of enterprise architecture in organizations is to align business strategy with information technology infrastructure. By creating a structured framework, enterprise architecture helps identify the necessary resources and processes to achieve organizational goals while managing complexity. It facilitates standardization, promotes interoperability among systems, and enhances overall efficiency. Additionally, enterprise architecture provides clarity in decision-making, ensuring that all technology initiatives support the overarching vision of the business. Effective implementation can lead to reduced costs, improved agility, and better risk management for the organization.
