Designing Service Oriented Modelling Architecture in Customer Service Management at the Catholic Church of the Archdiocese of Jakarta

The role of information technology today is increasing in the sector of modern people's lives. The development of this information technology needs to be responded to by the Catholic Church by updating the IT system, in accordance to the motto "Ecclesia semper Reformanda" (the church must continue to update itself). In this spirit, the Catholic Church of the Archdiocese of Jakarta (KAJ Church) seeks to respond the changing times with the applications that are easy for devotees in the ministry. However, the existing applications operate separatedly (not integrated), therefore it is very difficult for data to provide in real time, duplicate data and create application silos, and causes services for customers to be hampered. As the result, IT groups find it difficult to support the speed of change required by the organization due to the relatively long application development process with the continued dependency between each application silo. Therefore, the right solution is needed for some of the above problems to improve the system and architecture of different platforms and databases (interconnection between applications). To make it easier for organizations to adapt the changes, especially in bringing together the management of applications and facilitating the process of developing systems going forward, the KAJ Church needs to implement a Service Oriented Architecture (SOA)-based system with a wealth of applications. This update was done with the implementation of Service Oriented Modelling Architecture (SOMA) methodology, especially customer service management implementation. The implementation of SOMA is necessary to facilitate organizations to adapt changes, especially to integrate existing applications and to develop systems in the future. SOMA methodology represents a high level view work process that starts from the data collection process, the ongoing business process, the issues found in the field, the proposed solutions, to the process of implementing the selected solution until the implementation stage. The implementation of SOMA is not only limited to cost and energy savings from application development efforts, but ultimately the realization of an organization that is able to quickly adapt the business processes in it in order to be able to respond to the latest market demands. The goal is for KAJ church to provide better Customer Services, be more accurate, effective and efficient and able to help donors to provide appropriate assistance funds.
