Abstract

A change is a challenge since it is unpredictable and can happen anytime. The enterprise systems have to be responsive to changes. The change will cause alteration in the application and/or existing database if it is not supported by flexible system and adaptable environment. Service Oriented Architecture (SOA) support a mechanism for reusability and seamless integration. In order to anticipate the changes and to improve information services, Business Process Management (BPM) and Service Oriented Architecture (SOA) need to be synergized. Some previous researches have synergized BPM and SOA to endorsed the creation of flexible enterprise system environment, but lack in detailing how to determine and manage commonality and variability features in application software. This Study is illustrated in the Indonesian e-government Enterprise System. Since Indonesia has central and local governments, there are some commonality and specificity of rules and policies. Beside that, there are similarities and dissimilarities of rules and policies among local governments. Hence, to optimize the possibility of intersection and interrelated among common and specific components are needed. Those intersection and interrelated components are integrated in Zuma’s e-government Framework (ZEF). This framework consists of four layers: legacy layer, component layer, technical layer and business layer. The layers guaranteed the alignment of rules and policies among central and local governments in the e-government enterprise initiatives.
