QUALITY OF PROCESS ? A BUSINESS PROCESS PERSPECTIVE ON QUALITY OF SERVICE

The fundamental paradigm shift from a product- to a service-oriented economy implies novel technical and organizational challenges. The resulting dynamic of the technical infrastructure and the increasing development towards requesting external business services to be integrated into end-to-end business processes requires mechanisms ensuring the reliability of the organization?s composed services, workflows and business processes. From a business perspective, QoS characteristics defined based on technical services within the infrastructural layer have to be aggregated to more business-relevant Key Performance Indicators on business process layer to express the Quality of Process. These KPIs represent quality that is highly related to the business?s performance (e.g. processing time of a business service) and are crucial for achieving predefined goals in order to stay competitive in the market. The contribution of this paper is threefold: We (i) provide an in-depth requirements analysis for such a holistic quality management framework, we (ii) develop a holistic aggregation framework which enables service level aggregation incorporating the loosely coupled structure of business processes with invoked systems and services in an instance based manner. To demonstrate the expressive power of our framework we (iii) provide an exemplary industrial application scenario and illustrate the functioning and interplay of the designed artifacts

A service-oriented technical framework for the development of integrated education management information system

The increasing demand for education, especially tertiary education, has triggered a lot of challenges within the university system, especially in developing nations like Nigeria. These challenges include management and administration of the following: students’ enrolment, staff and students profile information, tuition fees payment, course registration, examination, and result processing, among others. The development of various types of Education Management Information Systems (EMIS) to alleviate these challenges has presented a more efficient means of optimising processes in the university systems. Thus, stakeholders within the university system: administrators, lecturers and students interact with the EMIS to ease their respective academic activities. However, these EMIS are designed, developed, and deployed with different application platforms and programming standards, which make it difficult for different EMIS to share information as they act as isolated information island. Thus, there is a challenge of data exchange in integrating different EMIS to achieve cross platform data exchange. Meanwhile, there are such initiatives on standard frameworks for the integration of disparate systems that are found in education institutions like the Education Management Information System Interoperability Framework (EMIF) and the School Interoperability Framework (SIF). However, the complexity in the mechanism for data exchange of these frameworks and the limited focus on the design structure of EMIS that can easily adapt and integrate limit their use in education institutions, especially those in developing countries with limited technical manpower and knowhow. In the search for a simplified framework that reconsider EMIS as an integrated system that can seamlessly exchange data, this research study involved the investigation, design, demonstration, and evaluation of a service-oriented technical framework for the development of integrated EMIS using the design science research methodology. This study, therefore, contributed to knowledge with the proposition of a technical framework that simplifies and standardizes the development of integrated EMIS that seamlessly exchange data among different functional modules. The technical framework is designed based on the identified layered conceptual components: a) Education Information Structure (EIS) that provides adaptable Central Information System (CIS) for handling the specific information requirements of different education systems with Access Control that provides a layer of security services to check and grant authorization and authentication access; b) Service-Oriented Design layer that handles integration of functional modules to connect with the EIS with service interfaces using Representational State Transfer Application Programming Interface (REST API); c) Demonstration Logic layer that recognizes the development platform and the flexibility of the programming logic to scale with new information requirements; d) Data Exchange Mechanism that provides a layer of standard data serialization format using Java Script Object Notation (JSON) to exchange data, through the RESTful API services, among functional modules in the Service-Oriented Design layer and the CIS in the EIS layer; e) Database System layer that handles data storage and requests from services. Thus, the framework makes key contributions with provision for customisation and multi-tenant cloud approach for adaptability and standardisation of the development of integrated EMIS to fit into different education systems. It was demonstrated on a web-based platform using the Laravel development platform that offer framework for rapid application development. The demonstration considered a case study approach, and the evaluation was based on expert reviews and comparative analysis within the context of the key requirements from the research findings. These requirements are: a) Adaptability that consider the suitability to fit into the specific information requirement of the different education systems; b) Maintainability that underscore the use of simplified common technologies that can be delivered within the knowledge of the EMIS developer; c) Standardization that check for the use of standard technologies and techniques; d) Scalability that consider provision for extension of the CIS and the functional modules to respond to changes in information requirements of the education system; e) Connectivity that benchmark access to shared data sources by the different functional modules of the integrated EMIS; f) Accessibility that benchmark usability of the platform to deliver user expectations on cross-platform data for presentation. In essence, the technical framework is appropriate for the development of an integrated EMIS that uses simplified technologies and techniques for achieving EMIS integration. While the framework addressed the integrated EMIS development that achieve seamless data exchange and scalability using the service endpoint extensions, the issues of optimizing the framework for enhanced security and performance are open to further research.School of ComputingPh.

Invited Paper: A Generalized, Enterprise-Level Systems Development Process Framework for Systems Analysis and Design Education

Current academic and industry discussions regarding systems development project approaches increasingly focus on agile development and/or DevOps, as these approaches are seen as more modern, streamlined, flexible, and, therefore, effective as compared to traditional plan-driven approaches. This extends to the current pedagogy for teaching systems analysis and design (SA&D). However, overemphasizing agile and DevOps neglects broader dimensions that are essential for planning and executing enterprise-level systems projects. Thus, a dilemma may arise: do we teach agile and DevOps techniques that may be inadequate for enterprise-level projects or do we teach the wider range of plan-driven skills and techniques that may conflict with the tenets and benefits of agile and DevOps? In this paper, we advocate for resolving this dilemma by adopting a generalized process framework that both fully supports enterprise-level projects but can also be selectively scaled back toward increased agility for smaller, less complex projects. In its full realization, this framework combines extensive project planning and up-front requirements with iterative delivery – an increasingly popular approach today for enterprise projects. In scaling back toward agile, the framework carefully accounts for system, environment, and team characteristics. Further, the model emphasizes issues frequently underemphasized by agile approaches, including the use of external software such as commercial-off-the-shelf (COTS), Software- as-a-Service (SaaS), and open source products and components; the need for business-oriented project planning and justification; and support for change management to ensure successful system adoption. The framework thereby flexibly accommodates the full range of activities that software projects must support to be successful

Evaluating how agent methodologies support the specification of the normative environment through the development process

[EN] Due to the increase in collaborative work and the decentralization of processes in many domains, there is an expanding demand for large-scale, flexible and adaptive software systems to support the interactions of people and institutions distributed in heterogeneous environments. Commonly, these software applications should follow specific regulations meaning the actors using them are bound by rights, duties and restrictions. Since this normative environment determines the final design of the software system, it should be considered as an important issue during the design of the system. Some agent-oriented software engineering methodologies deal with the development of normative systems (systems that have a normative environment) by integrating the analysis of the normative environment of a system in the development process. This paper analyses to what extent these methodologies support the analysis and formalisation of the normative environment and highlights some open issues of the topic.This work is partially supported by the PROMETEOII/2013/019, TIN2012-36586-C03-01, FP7-29493, TIN2011-27652-C03-00, CSD2007-00022 projects, and the CASES project within the 7th European Community Framework Program under the grant agreement No 294931.Garcia Marques, ME.; Miles, S.; Luck, M.; Giret Boggino, AS.

A survey on quality of service support on middelware-based distributed messaging systems used in multi agent systems

The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-642-19934-9_10Messaging systems are widely used in distributed systems to hide the details of the communications mechanism to the multi agents systems. However, the Quality of Service is treated in different way depending on the messaging system used. This article presents a review and further analysis of the quality of service treatment in the mainly messaging systems used in distributed multi agent systems. The review covers the issues related to the purpose of the functions provided and the scope of the quality of service offered by every messaging system. We propose ontology for classifying and decide which parameters are relevant to the user. The results of the analysis and the ontology can be used to select the most suitable messaging system to distributed multi agent architecture and to establish the quality of service requirements in a distributed system.The study described in this article is a part of the coordinated project SIDIRELI: Distributed Systems with Limited Resources.

Aligning a Service Provisioning Model of a Service-Oriented System with the ITIL v.3 Life Cycle

Bringing together the ICT and the business layer of a service-oriented system (SoS) remains a great challenge. Few papers tackle the management of SoS from the business and organizational point of view. One solution is to use the well-known ITIL v.3 framework. The latter enables to transform the organization into a service-oriented organizational which focuses on the value provided to the service customers. In this paper, we align the steps of the service provisioning model with the ITIL v.3 processes. The alignment proposed should help organizations and IT teams to integrate their ICT layer, represented by the SoS, and their business layer, represented by ITIL v.3. One main advantage of this combined use of ITIL and a SoS is the full service orientation of the company.Comment: This document is the technical work of a conference paper submitted to the International Conference on Exploring Service Science 1.5 (IESS 2015

A Framework for Evaluating Model-Driven Self-adaptive Software Systems

In the last few years, Model Driven Development (MDD), Component-based Software Development (CBSD), and context-oriented software have become interesting alternatives for the design and construction of self-adaptive software systems. In general, the ultimate goal of these technologies is to be able to reduce development costs and effort, while improving the modularity, flexibility, adaptability, and reliability of software systems. An analysis of these technologies shows them all to include the principle of the separation of concerns, and their further integration is a key factor to obtaining high-quality and self-adaptable software systems. Each technology identifies different concerns and deals with them separately in order to specify the design of the self-adaptive applications, and, at the same time, support software with adaptability and context-awareness. This research studies the development methodologies that employ the principles of model-driven development in building self-adaptive software systems. To this aim, this article proposes an evaluation framework for analysing and evaluating the features of model-driven approaches and their ability to support software with self-adaptability and dependability in highly dynamic contextual environment. Such evaluation framework can facilitate the software developers on selecting a development methodology that suits their software requirements and reduces the development effort of building self-adaptive software systems. This study highlights the major drawbacks of the propped model-driven approaches in the related works, and emphasise on considering the volatile aspects of self-adaptive software in the analysis, design and implementation phases of the development methodologies. In addition, we argue that the development methodologies should leave the selection of modelling languages and modelling tools to the software developers.Comment: model-driven architecture, COP, AOP, component composition, self-adaptive application, context oriented software developmen
