Collaborative systems Quality management discipline requires a set of assessment mechanisms to evaluate external quality characteristics influenced by environmental parameters and impacted by ecosystem factors. The present paper suggests a new assessment oriented model to assess and monitor quality performance. The proposed model, named RatQual, gives a hierarchical categorization for collaborative systems quality factors. RatQual is designed to quantify dependent-environment qualities by considering internal, external and in use aspects. This model is supported by a tool that automates the assessment process. This tool gives assistance in quality evolution planning and serves for periodical monitoring operations used to enhance and improve information system quality.

Service sharing is a prominent operating model to support business. Many large inter-organizational networks have implemented some form of value added integrated services in order to reach efficiency and to reduce costs sustainably. Coupling Service orientation with enterprise architecture paradigm is very important at improving organizational performance through business process optimization. Indeed, enterprise architecture management is increasingly discussed because of information system role as part of achieving the strategic direction of value creation and contribution to economic growth. Also, system architecture promotes synergy and business efficiency for inter-organizational collaboration. For this purpose, this work proposes a review of service oriented enterprise architecture. This review, enumerates several integrative and collaborative frameworks for integrated service delivery.

Organizations have to efficiently manage efforts they deploy in order to enhance and ensure information system quality. Unlike other research works addressing this issue, the present proposal handle quality characteristics, such interoperability and security, by taking into account the subsisting complementarity between the different quality factors, their interactions and mutual effects. This paper considers the use of multiobjective optimization techniques in order to plan effectively quality evolution in inter organizational context. To ensure this effectiveness goal, this paper proposes initially a model to represent quality evolution and planning. Quality degrees are evaluated using ratio metrics taking into account all operational assessment aspects. In a second stage, a Multi Objective Particle Swarm optimization (MOPSO) algorithm is used as a heuristic optimization technique to obtain the best efforts distribution in collaborative networks.

Our study is primarily interested in limiting the spread of malwares via SMS/MMS, and Emails. It describes the steps leading to identify, analyze and secure traffic in mobile networks. For this purpose, a Framework MPSS has been used to be part of the network of the mobile network operator. MPSS aims to increase the level of information security across the telecom provider network in order to resolve the problems of the limited hardware and software resources on those mobiles devices. Finally, a new study based on MPSS Framework limitations, has driven a designing of a new Framework called MPSS2 based in the private Mobile Cloud Computing of the ISP. In addition, with the approach of MCC, the proposed security takes the form of a service provided by the mobile network operator (SaaS: Security as a Service). Therefore MPSS2 has the main objective to limit the risk of losses of personal and professional user’s data.

Optimizing Resource allocation and effort dispatching of interoperability enhancement is a key requirement to effectively setup, develop and evolve intra and inter organizational collaboration. To ensure this objective of effectiveness, this paper proposes initially an approach for representation of interoperability evolution and planning. Interoperability degree is assessed using a ratio metric taking into account all the significant aspects such as potentiality, compatibility and operational performance. In a second stage, a Modified Particle Swarm optimization (MPSO) algorithm is used as a heuristic optimization method to find the best distribution of effort needed in collaborative networks.

Information System Quality (ISQ) management discipline requires a set of assessment mechanisms to evaluate external quality characteristics that are influenced by the environmental parameters and impacted by the ecosystem factors. The present paper suggests a new assessment oriented model that takes into consideration all facets of each external quality feature. The proposed model, named RatQual, gives a hierarchical categorization for quality. RatQual is designed to quantify dependent-environment qualities by considering internal, external and in use aspects. This model is supported by a tool that automates the assessment process. This tool gives assistance in quality evolution planning and serves for periodical monitoring operations used to enhance and improve information system quality.

In front of the increasing complexity of information systems, improving enterprise interoperability has become a crucial element for better management. To address this issue, several research projects have been launched during the last decade and have resulted in a set of frameworks which help organizing and performing enterprise interoperability projects efficiently. In addition to these frameworks, many metrics have been also developed to measure the interoperability degree between systems. However, these frameworks and metrics are not sufficient to better control execution of these projects. Indeed, they don’t take into account resource management and unanticipated events or situations that can be encountered during execution. Moreover, there is a real lack in methodologies to deal with this situation. The aim of this paper is to introduce a new approach to control interoperability improvement projects execution by using control theory, project planning theory and a specific quantitative interoperability metric RatIop.

Many frameworks are available today to help organizing and performing Enterprise Interoperability projects efficiently. There are also many metrics available to measure the interoperability degree between systems. However, there is a real lack in methodologies to control Enterprise Interoperability improvement projects execution. The aim of this paper is to introduce a new approach to control interoperability improvement projects execution by using control theory, project planning theory and RatIop.

In the project management domain, the cost, time and quality triangle, called "iron triangle", is used to model project constraints and to define its main goals. The cost and time dimensions are highly mature and stable, but the quality dimension is considered under-researched in projects by many authors. In this paper, we will focus on "interoperability degree" as a quality factor of information systems based on heterogeneous components that interact and exchange information between them. We will also present a methodology to manage and control execution of interoperability degree improvement projects. The proposed methodology will be based on mature and proved tools and frameworks like Control Theory and Project planning theory.

Collaborative networks are constituted by a variety of entities that collaborate to better achieve common or compatible goals. Sharing IT resources in these networks is widely practiced and takes many forms. This fact faces inter organizational information system to many challenges and implies many quality issues. In this context, the Information System Quality (ISQ) management discipline requires a set of assessment mechanisms to evaluate quality characteristics and to plan their evolutions. This paper aims to present a novel model for assessing external quality characteristics of process driven services. The characterization, as proposed here, aims to quantify dependent environment qualities by considering internal, external and in use aspects.

Delivering added value public e-services often requires cooperation between two or more government departments. In general, such cooperation is ensured by implementing interoperability between automated business processes. In spite of the existence of several works interested in public online services in general, only few of them were focused on measuring interoperability degree, whether used or required, to deliver them. In this context, the objective of this paper is to propose a new quality indicator for interoperability assessment of public integrated e-services. This indicator takes into account three main aspects: interoperation potentiality, interoperation compatibility and operational performance. Finally, to better illustrate how to use the proposed measurement method, we present a practical example of integrated public e-service. This work takes the case of a national library which proposes an online registration service.

Interoperability is one of the most challenging concerns that face healthcare information system (HIS) actors. Interoperability implementation in this context may be a data exchange interfacing, a service oriented interaction or even a composition of new composite healthcare processes. In fact, optimizing efforts of interoperability achievement is a key requirement to effectively setup, develop and evolve intra- and interorganizational collaboration. To ensure interoperability project effectiveness, this paper proposes a modeling representation of health processes interoperability evolution. Interoperability degrees of involved automated processes are assessed using a ratio metric, taking into account all significant aspects, such as potentiality, compatibility and operational performance. Then, a particle swarm optimization algorithm (PSO) is used as a heuristic optimization method to find the best distribution of effort needed to establish an efficient healthcare collaborative network.

This paper aims to clarify how to foster healthcare alignment in integrated delivery network (IDN) through interoperability enhancement. It presents an approach for assessing alignment of integrated healthcare information systems (HIS). In the case of alignment gaps in the integrated delivery network due to a lack of interoperability, it is quite important to have the means to plan point to point interoperability scenarios. This paper proposes a novel approach of processes interoperability evolution, which aims at finding the best effort distribution needed to establish efficient Integration Delivery Network (IDN). Keywords: Strategic Alignment, Healthcare Information System (HIS), Integrated Delivery Network (IDN), Interoperability planning.

Public administration has to prepare itself to deliver fully integrated eGovernment services. This delivery often requires cooperation via business processes interoperability across two or more departments. In this context, public departments and agencies need to implement interoperability using enterprise architecture techniques to structure business processes, and service oriented models to achieve their integration. Thus, it's quite interesting to adopt enterprise architecture paradigm and techniques to analyse, track and control the evolution degree of processes interoperability from the existing "as-is" state to the future "to-be" state. The present paper proposes a periodic monitoring approach based on an assessment method which considers three main aspects of interoperation: 1. Potentiality, reflecting the preparation to interoperate. The objective is to foster interoperation readiness by eliminating barriers that may obstruct the interaction. 2. Compatibility, referring to interoperation implementation through adequate engineering process. It aims to study the relation between the external interfaces of processes and the surrounding environment in order to ensure effective interaction. 3. Performance efficiency, focusing on monitoring operational performance. It consists of the availability assessment of the communication infrastructure and the supporting system in general. It considers also end users satisfaction of interoperation in use. The proposed method supporting tool, (IMT) for interoperability monitoring tool, assesses interoperability degree periodically through five steps: (i) Delineating the scope of interoperation; (ii) Quantifying the interoperation potentiality; (iii) Calculating the compatibility degree; (iv) Evaluating the operating performance; (v) Aggregating the degree of interoperability. In addition to its capacity to track the evolution of interoperation degree in time, the IMT measures the required effort to reach a planned degree of interoperability. Finally, to better illustrate how to use the proposed interoperability monitoring approach, we present a practical example of integrated public eService. It's a citizen oriented eService proposed by a public hospital that offers special fees for persons covered by social security insurances. It includes government to business collaboration and government to government one.

Business collaboration networks provide collaborative organizations a favorable context for automated business process interoperability. This paper aims to present a novel approach for assessing interoperability of process driven services by considering the three main aspects of interoperation: potentiality, compatibility and operational performance. It presents also a software tool that supports the proposed assessment method. In addition to its capacity to track and control the evolution of interoperation degree in time, the proposed tool measures the required effort to reach a planned degree of interoperability. Public accounting of financial authority is given as an illustrative case study of interoperability monitoring in public collaboration network.
