Consulting firms in enterprise architecture that develop projects through the TOGAF framework may generate valuable knowledge from project to project. However, for this knowledge to create value, it must be supported by an effective ability to capture, store and reuse it. This paper proposes a knowledge management framework focused on TOGAF initial phases to enable reusing lessons from previous projects. Through a specific meta-model, it offers âways ofâ thinking, working, supporting, controlling and modelling this process. As a result, we present some steps to develop knowledge management in TOGAF-based enterprise architecture projects through a case study in a consulting firm.
