This Enterprise Architecture Board (EAB) Guide is designed to address several major purposes:rn• EAB Process Overview. Help all DHS personnel—especially leadership, program personnel and EAB stakeholders —understand the role of the EAB in supporting Enterprise Architecture (EA) and EA stakeholders within DHS, as well as for DHS enterprise processes.rn• Practitioners’ Guidance. Assist DHS personnel in understanding, aligning their activities with, preparing for, and executing the EAB process.rn• EAB Outreach, Support and Reviews. The EAB’s primary operational activity is planning and performing Reviews. EAB Reviews are comprehensive and right-sized to their position in a specific program’s lifecycle. They support critical recommendations and decisions at key points for managing acquisitions, investments, and capabilities, primarily within the Acquisition Lifecycle Framework (ALF), and specifically prior to an Acquisition Decision Event (ADE). The EAB initiates outreach, provides expert guidance and support to program stakeholders, assesses inputs and artifacts, and provides recommendations.
