Overview The Department of the Interior's (DOI) Enterprise Architecture (EA) program provides strategy, planning, business analysis, and decision support services for DOI’s information technology (IT) portfolio, ensuring investments properly fulfill mission needs, while ensuring DOI's compliance with the Office of Management and Budget's (OMB) Federal Enterprise Architecture (FEA), and Congressional, OMB, and Government Accountability Office (GAO) directives. Through these services, the program helps DOI plan and implement business and IT solutions and guide its IT investment portfolio. The DOI EA program supports numerous DOI programs by providing information, analysis, and capabilities to: Support strategic planning and alignment of business and Information Management and Technology goals and objectives; Support IT Capital Planning and Investment Control (CPIC) and portfolio management processes; Maintain baseline and target architecture information, including the application composition of DOI IT investments; Ensure alignment with relevant cross-agency and government-wide initiatives; Develop and institute governance structures & processes; Collaborate with business and management functions across DOI to develop; Business strategies; Modernization plans; and Segment roadmaps. The DOI EA program also develops analytical frameworks for: Identifying opportunities for collaboration, reuse, data sharing and consolidation; Ensuring information security management requirements are integrated into budget formulation; and Identifying enterprise services that can be leveraged across the Department. Segment Roadmaps The segment roadmaps are living plans that identify, prioritize, and monitor the projects to achieve target states in priority IT and business capabilities across a 5 year time frame. The DOI EA program provides standards and guidance and collaborates with bureau and office stakeholders to develop segment roadmaps. Transition to Internet Protocol Version 6 IPv6 -DOI has designated the DOI Chief Enterprise Network Architect to lead DOI’s Integrated Project Team to support activities of the Office of Management and Budget (OMB) Memorandum 21-07 (M-21-07). The intent of this strategic initiative is to phase out the use of IPv4 for all current DOI systems as soon as practical by meeting the milestones described in the attached link to the OCIO’s policy memo. Please find attached the OCIO Memorandum, "Transition to Internet Protocol Version 6." The IPv6 transformation supports modernization of our network to make it inherently more secure and will provide increased capacity to accommodate the expansion of the internet of things.
