A New Method for Enterprise Architecture Assessment and Decision-Making about Improvement or Redesign

In the process of Enterprise Architecture Planning, the “As-Is” architecture is considered as baseline architecture, and target-architecture is designed on its basis. However, in some enterprises, particularly in developing countries, “as-is” architecture is not a suitable basis for creating target architecture. One method of improvement and correction of organizational architecture is using enterprise architecture maturity. In such cases, improvement efforts will not only fail to improve the procedures, but also consume time and financial and human resources of the organization. That is why it is recommended to redesign the organizational architecture instead of organizational architecture improvement. In this paper, multifactor systems are used to provide a practical method for assessment of any given organization and making accurate decisions on improvement or redesign of its architecture based on missions, goals and restrictions of the organization. With the use of this method, the enterprise architectures can be assessed and an accurate decision about development of the enterprises can be made based on its mission.
