Center node: "Configurable process models for the swedish public sector"
  Abstract: Process orientation and e-services have become essential in revitalizing local government. Although most municipalities offer similar services there is little reuse of e-services or underlying process models among municipalities. Configurable process models represent a promising solution to this challenge by integrating numerous variations of a process in one general model. In this study, design science is used to develop a configurable process model to capture the variability of a number of different processes. The results include a validated configurable process model for social services, a benefits analysis and directions for future development. Although the results are perceived useful by municipal officials, there are several challenges to be met before the benefits of configurable process models are fully utilized.
