Managing an EA


EA Governance defines the rules and policies controlling the development and evolution of the EA program, and allocates responsibilities, authorities, and decision rights across key stakeholder groups. Stakeholders include not only the developers of the EA but others who may be impacted by its development such as the CIO, the Chief Information Security Officer (CISO), business leaders, and IT managers. Stakeholders often have different concerns and priorities, and some may be in conflict. The EA governance process establishes mechanisms to resolve conflicts and reach decisions. Enterprises may decompose EA decisions (e.g. EA principles, data privacy policies, IT infrastructure strategies, business applications, IT investments), and allocate different decision authorities across stakeholder groups. For example, the CISO and IT leaders may be given control over the evolution of the IT infrastructure, and seek inputs from business leaders. The balance of control may be reversed for business applications decisions. In cases where control and authorities are decomposed and distributed, mechanisms are needed to ensure consistency and compatibility across the enterprise.
