Which ADM phase typically follows the definition of Target Architecture?

The phase that typically follows the definition of Target Architecture in the Architecture Development Method (ADM) of TOGAF is Phase E, known as the Opportunities and Solutions phase.

In this phase, once the Target Architecture has been defined in Phase D, the focus shifts to identifying how to implement that architecture. This involves exploring various options for realizing the architecture, analyzing the gaps between the current state and the Target Architecture, and determining which solutions are feasible. The work done in Phase E lays the groundwork for transition planning and implementation, ensuring that the defined architecture can be effectively and efficiently realized.

By understanding Phase E in this context, it becomes evident how it directly builds upon the work completed in Phase D, making it a crucial step in the overall architecture development process within TOGAF.
