This article describes the Methodology for Business Transformation v1.5 and how it can be used as a step-by-step approach for developing architecture. The recent publication of OMB’s Federal Enterprise Architecture (FEA) Practice Guidance clearly articulates the inter-relationships between the three architecture levels: enterprise, segment, and solution. This article introduces the MBT v1.5 as a practical approach to developing these architecture levels with executive and mission area leadership, participation, and buy-in. This article is written to encourage federal and private sector architecture practitioners to use the MBT in their own organizations. The MBT is feely available as an open-source methodology . It is available at
