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.
