Service specification and service compliance: How to consider the responsibility dimension?

Service engineering is a huge research topic that addresses the specification, the compliance and the sharing of business and IT services across companies, institutions or governmental organizations. Despite many advantages of working with the services, the guarantee of service compliance and management of the service overlaps by the stakeholders remains challenging. The objective of this document is to present a methodological approach in order to specify the links between the organizational layer and the informational layer of services. Therefore our research has focused on clarifying the responsibility dimension of the stakeholders involved in those services. The proposed approach is illustrated with an example in the context of sensitive data exchange between stakeholders from the healthcare domain.

Service specification upon multiple existing information systems

This paper presents an approach for the specification of business services upon multiple existing information systems (IS). Indeed, the challenges that a service architect has to face with the IS complexity from one side (due to the intertwinement of the organisational, informational, technological and ontological spaces), the complexity of its evolution from the other, and often multiple existing information systems, require a proper guidance and a methodological framework in order to implement new business services. We thus propose a process model with a referential of analysis (SAM) to support our approach and we discuss it in the context of the e-government services engineering.

Designing the Shift from Information Systems to Information Services Systems

Service-oriented paradigm is emerging as a promising solution to handle enterprise information systems (IS) complexity, interoperability, and evolution issues. However, the shift from a conventional IS architecture to a service-oriented one is not an easy task. Various approaches have been proposed in the literature and most of them deal with either business strategic service design or a technical level IS transformation and migration. There is a need for approaches forming the link between these two levels and designing the information level transformations. In the paper, the concepts of information service and information services system (ISS) are promoted and three different ways to design information services and ISS are proposed taking into account enterprise legacy IS evolution. The three approaches are illustrated with examples taken from industrial projects and case studies.

Towards a Generic Approach for the Management and the Assessment of Cooperative Work

Cooperative work, teamwork or networking of individuals and collective-labors have become the key elements in modern organizations. These new forms of work organization have favored the birth of Computer-Supported Cooperative Work tools (CSCW), who study the individual mechanisms as well as the group-work collectives and then research how to assemble and cooperate many actors with various skills and different prerequisites. However, despite the enormous benefits of CSCW, few of these ones focus on the assessment aspect. Thus, this paper proposes a generic approach which combines Workflow Man-agement Systems (WfMS) with generic design patterns in order to generate a model for the management and specifically for the assessment of cooperative processes and their final rendering.

From Information Systems to Information Services Systems: Designing the Transformation

Service-orientation is currently considered as a promising paradigm to deal with the complexity, interoperability and evolution of enterprise Information Systems (IS), which are the foremost preoccupation in today’s enterprises. However, the shift from a conventional IS architecture to a service-oriented one is not an easy task despite of the various service design approaches proposed in the literature. In this paper we promote the concepts of information service and Information Services System (ISS) and we present three different ways to design an ISS taking into account enterprise legacy IS and/or from scratch. We illustrate the three approaches with examples taken from industrial projects and case studies.

Evaluation of e-government information systems agility in the perspective of sustainability

Agility and sustainability are two relatively recent concepts which interest more and more the researchers in management and information systems. However, in spite of their growing popularity in all fields of knowledge, the conceptualization of these concepts is not achieved yet in the egovernment field, and then remains completely open. The aim of this paper is to conceptualize them while flying over the existing state of the art dealing with the principle approaches of agility and sustainability of systems; and then to contribute to these works by suggesting a components oriented-method for the evaluation of e-government information systems agility in the perspective of their sustainability. This method is based on Methods Engineering discipline and thus, it is built in the form of components guiding the process of evaluation.

BPM-based framework for e-government processes improvement: legal requirements integration

An e-government system is articulated around a set of governmental processes offering a new era of greater convenience in stakeholder access to governmental information and services. However, a survey of e-government implementations has brought out that most governmental institutions have not transformed and improved their supporting processes. This has led to a big gap between the deployed portals and the expected promises because they attribute more attention to their web-based portals away from their supporting governmental processes. Consequently, this work considers the Government Process Management lifecycle, especially the designing phase in order to design efficient governmental processes according to their legal basis. Indeed, for governmental processes, all design choices should be backed by legal-texts. To do so, the developed approach is articulated around two main levels, namely the legal design and the operational design. Its main purpose is to produce common governmental processes models, explicit legal requirements representation, and shared domain concepts and services.

Personalization of Legal and Ethical Information in ICT Platforms: The Approach of Legal Decision Tree

This paper aims at presenting a theoretical approach for the representation of legal and ethical information in a personalized way in ICT platforms. The personalization process allows us to adapt the legal information for end- users of ICT platforms. This approach points out the key element for defining a complete legal and ethical corpus of documents. Based on the corresponding scenario, the legal information is selected, filtered and then presented in ICT platforms. For organizating and analyzing this legal and ethical information, we reuse the existing notion of the decision tree and enhance it with a set of legal parameters emerging from legal documents. This legal decision tree will help us to treat different types of legal cases, which may relate to different service scenarios.

Ontology based information system application (OBISA)

Services are the core business of each organization. But business services identification leads often to compliance problem with the legal sources. The main reason to this conflict is due to a miss communication between Business Law experts, Business stakeholders and the Business services designers. To resolve this problem we propose in this paper a collaborative application named OBISA that allow all concerned actors to collaborate together in identifying and extracting of Business services from the legal sources.

Innovation and evolution of services: role of initiatives

This paper discusses the role of initiatives in dynamic collaborative processes of services innovation and evolution in the organizational context of an enterprise. The research is based on the current state of the art on modeling initiatives and services and studies phenomena of innovation and evolution for supporting services. Within our approach, we propose definitions for the key concepts related to modeling processes of services innovation and evolution, and define their main characteristics, stakeholders and roles. Furthermore, we introduce our services-oriented approach for initiatives management and show how it could be used for the process of services innovation through knowledge actionalizing. This theoretical founding is then discussed from the implementation viewpoint: we introduce a trans-disciplinary collaboration platform, Cross-Pollination Space, and briefly describe its framework. We conclude with the scope of current work and identify some context limitations of this research and reposition them as perspectives for our future work.
