A staple in enterprise architecture TOGAF interview questions for experienced, be prepared to answer this one using your hands-on experience. While enterprise architects construct a target architecture from the baseline architecture, it does not have to be the case every time. So, TOGAF  architect interview questions  may contain questions about transition architecture. With this question, you have two parts. So ensure to answer both the parts with equal weightage. So start by defining transition architecture and then elaborate on its components. Transition architectures may be understood as an intermediate between baseline and target architectures. A Transition Architecture offers a formal definition of one stage of architecture that symbolizes an important period in architecture. However, for a definition, you can say, "Transition architecture expresses the advancement of design construction from the baseline to the target architecture." A transition architecture showing the progress of an ongoing architectural design will consist of components like milestone implementation factor (that describes each milestone achieved in progress), opportunity portfolio, work package portfolio, close gaps (to check the gap between the baseline and target architecture), and so on. While answering the second segment, you can just like the components. You can say, "The components of transition architecture are milestone implementation factor, close gaps, opportunity and work package portfolio, assessment matrixes, solutions, etc.
