Introduction
TOGAF (The Open Group Architecture Framework) and ArchiMate are powerful tools for planning and executing digital transformation initiatives. TOGAF provides a structured methodology for developing enterprise architectures, while ArchiMate offers a standardized language for modeling and visualizing these architectures. Together, they form a robust framework for aligning business strategy with technology solutions.
TOGAF Architecture Development Method (ADM)
The TOGAF ADM is a cyclic process that guides the development of enterprise architecture. It consists of several phases, each addressing specific aspects of the architecture. These phases can be adapted and customized to meet the unique needs of any organization.
