Upon learning that business units have been independently procuring cloud services, the IT steering committee's best course of action is to define a procurement strategy based on business unit needs. This approach ensures that cloud service procurement aligns with the enterprise's overall IT strategy and governance policies while still addressing the specific requirements of individual business units. It fosters collaboration between IT and business units, ensuring that cloud services are vetted for compliance, security, and interoperability. Requiring cancellation, including business unit leadership in the EA review board, or limiting usage to open-source solutions may address aspects of the issue but do not provide a comprehensive strategy that aligns business needs with IT governance.
