Designing an enterprise architecture government organization based on TOGAF ADM and SONA

In practice, many government organizations have representative offices or specialized units which are spread all over Indonesia. With the increasing development of information technology and the expansion in Indonesia areas, also the increasing need for information and communication technology, it would require a flexible, easily expandable, and sustainable IT Infrastructure. To create a sustainable and flexible IT infrastructures, it is necessary to align between IT needs and organization business, so that there will be mutual support between both entities. Enterprise Architecture (EA) can help to build that alignment, and service-orientation architectural approach will help to design the infrastructure. This EA will be developed by using collaboration and tailoring TOGAF ADM as EA framework and SONA (Service Architecture Network Architecture) as information system and technology design framework which are connecting network infrastructure, network services, and application. SONA will be used as reference for the phases of the cycle TOGAF ADM. This paper presents Volcanoes Monitoring System in Indonesia with a case study design for the proposed methodology. The result of this research is “Clear” status definition of EA work based on EA score card assessment, and this means EA work is well defined and documented.
