Local administratives face challenges similar to enterprises due to changes in their environment. Municipalities need to join their resources to reimburse and to deliver services. However, municipalities have not received much attention regarding ICT related integration, especially in cases when multiple municipalities are combined. Despite the central role of information systems in government services, ICT is often left without prior contemplation when making plans to integrate municipalities. Therefore, this paper addresses the role of information systems in municipality integration. In so doing, the study uses a framework described in prior literature: using this framework, the paper describes particular municipality integration and discusses IS-related factors in the implementation of integration.
