The Open Group Architecture Framework (TOGAF) is one of the most used by large-scale companies Enterprise Architecture (EA) frameworks. It contains the Architecture Development Method (ADM) to represent knowledge used to analyze and build the EA for an organization. It is a very detailed method and covers all phases of EA construction and maintenance. However, the described guidelines are hard to follow as they are rich and numerous. Our goal is to provide a process-based knowledge representation of the ADM method to better guide EA professionals using TOGAF and to facilitate the TOGAF teaching with students. In our previous work, we have already proposed the process-oriented graphical representation of the requirements management (RM) phase of TOGAF-ADM. In this work, we carried out a questionnaire to evaluate the process representation of the TOGAF-ADM RM phase in comparison with its textual representation issue from the TOGAF documentation. The obtained results confirmed that process models are helpful to better represent the knowledge included in TOGAF-ADM textual guidelines; thus, practitioners have a more complete description of how to proceed while using TOGAF.
