An Agile Approach for Converting Enterprise Architectures

Enterprise Architecture includes IT infrastructures, business processes and whole computer applications in an enterprise. Since such enterprise architecture is the backbone of corporates operating model and business processes, enterprise architecture conversions are very strategic projects. The general tendency for enterprise architecture conversion is big bang approach that is hard to be supported by executives as the results are very late for new architecture to prove. Because of complexity and trade-off between costs and risk, this paper suggests simple solution that starts the project with small core team. First task will be developing coexistence methodology between two systems in data level. By this solution the whole system is able to redesign smaller business projects step by step. It continues developing a prototype on simple business scenario that contains most common behavior of all enterprise architecture. The prototype's aim is to prove new design. The key success factor of this model is agility while managing divided projects and good management skill of the core team while developing new core business processes and system architecture.
