An increasing level of cooperation between public administrations nowadays on national, regional and local level requires methods to develop interoperable EGovernment systems and leads to the necessity of an efficient modeling of collaborative business processes and their implementation. In this paper a framework to systematically develop interoperable systems in the public sector is described. The methodology is motivated and explained on the basis of an E-Government reference model for the German Plan Approval Procedure. In this context it is described how cross-organizational business processes can be modeled and transformed to technical process models in the form of Web Service protocols. After a motivation for the need of interoperability frameworks and a description of related work, section 3 introduces the methodical interoperability framework. Further detailing the contents of this framework, section 4 presents a method for the creation of collaborative business processes on a conceptual level. Section 5 changes to the execution level and describes how to implement the conceptual models created before with Web Service protocols. Section 6 concludes the paper and gives an outlook on future research.
Abstract:Afier the initial phase of E-Government and the exaggerated expectations for the new internet-based technologies, a pragmatic state of mind has evolved during the last few years. Thereby, it is especially the evaluation of the related financial benefits that has become a crucial aspect. The paper presented outlines a process-driven approach for the analysis of technology-driven performance impacts based on performance indicators. From a German perspective, existing evaluation concepts were concretized for the case scenario of German Plan Approval ~rocedures.'
An increasing level of cooperation between public administrations nowadays on national, regional and local level requires methods to develop interoperable eGovernment solutions and leads to the necessity of an efficient evaluation and requirements engineering process that guides the establishment of systems and services used by public administrations in the European Union. In this article, the authors propose a framework to systematically gather and evaluate requirements for eGovernment in the large. The evaluation framework is designed to support requirements engineers to develop a suitable evaluation and requirements engineering process with respect to interoperable eGovernment solutions. The methodology is motivated and explained on the basis of a European research project.
Due to the increasing heterogeneity and dynamics of the economy, more and more enterprises are challenged to adapt continuously to rapid changes, to concentrate on their core competencies as well as to search for competitive advantages and innovations (e.g., Prahalad & Hamel, 1990). Rapid technological advances and altered customer demands create a new dynamic and complex business environment, which requires flexibility and mobility of enterprises (Camarinha-Matos, 2002). For these reasons, different enterprises have to cooperate in order to meet customer needs effectively, to encounter the contemporary prevalent high competition and innovation pressure as well as to be permanently successful in largely saturated markets. In this respect, the opening of an organization’s borders is no longer regarded as a necessary evil but rather as an opportunity of strategic importance. Current approaches mainly focus on the cross-enterprise integration of data, functions, and processes for operational purposes within such collaborative business structures (e.g., Adam, Chikova, Hofer, & Vanderhaeghen, 2005; Grefen, Aberer, Hoffner, & Ludwig, 2001; Schulz, 2002). The driving force behind such activities is to generate a win-win-situation for all partners, whether by creating new structures or by adapting the existing ones, realizing an optimization objective. However, how do you measure if this postulated win-win situation by concentration on core competences is really achieved? The question is: Has the cooperation yielded the objectives that had been determined in the run-up? Is the cooperation really as successful as it was intended to be or can it be improved?
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
