I would also stress that the Zachman EA framework is also another leading framework that is effective or in some application settings, it may be the best fit. The purpose is not to define the TOGAF. However, for the simplicity of reference, I will share the TOGAF ADM, which is the practice for EA management in TOGAF. The method combines the strategy and vision of an organization and its business or functions with a portfolio of change programs that recognize this strategy. TOGAF uses different architecture principles like business architecture, information architecture, which can be data and application, and technology architecture including a mechanism for connecting the strategy with execution and governance of change programs to provide on the
