Enterprise Architecture (EA) is a blueprint for improving, reengineering, and integrating best practice capabilities into programmatic and system solutions for emerging business needs. More specifically, it is a framework which outlines processes, tools, techniques, and their relationships to determine current and future needs across the enterprise to meet tactical and strategic objectives.
HRM EA can: • Help manage information technology (IT) investments; • Serve as a common lexicon of operational activities, capabilities, system functionality, and operational roles across the human resources community; • Provide an overarching framework for future HRM program development and enhancement; • Support alignment of IT with business objectives; • Support acquisition processes; • Foster interoperability among HRM, other federal agencies, and business partner systems; • Serve as a Capstone Architectural Framework for all HRM; • Serve as an enabler for conducting and documenting Continuous Process Improvements and Lean Six Sigma efforts across the HRM Core Business Mission.
