Organizations are permanently confronted with the need for adaptation to a complex business environment that is in a continuous change and transformation. Thus, the organization’s agility represents a key element in obtaining the strategic advantage and the market success. The paper analyzes the connection between the Service-Oriented Architecture (SOA), the Business Process Management (BPM) and the Decision Management, as well as the way in which these modern approaches contribute to obtaining organization agility. The main changes determined by the organization’s service orientation, changes that are necessary for the success of the transition to the agile organization, are also identified and presented within the paper. Obtaining and maintaining agility implies the existence of an agile architecture at the level of organization. For that matter, the final part of the paper analyzes the creation of an organizational architecture based on standards and oriented on services. Four relevant approaches have been selected, which joined may lead to obtaining an agile enterprise architecture, namely: SOA, Cloud Computing, BPM, and Decision Management.
