GQ-BPAOntoSOA: A goal- and object- based semantic framework for deriving software services from an organisation’s goals and riva business process architecture

Understanding a business organisation is a primary activity that is required for deriving service-oriented systems that assist in carrying out the business activities of an organisation. Business IT alignment is one of the hot topics that concerns with aligning business needs and system needs in order to keep a business organisation competitive in a market. One example in this area is the BPAOntoSOA framework that aligned business process architecture and the service-oriented model of computing. The BPAOntoSOA framework is a semantically enriched framework for deriving service oriented architecture candidate software services from a Riva-based business process architecture. The BPAOntoSOA framework was recently proposed in order to align the candidate software services to the business processes presented in a Riva business process architecture. The activities of the BPAOntoSOA framework are structured into two-semantic-based layers that are formed in a top-down manner. The top layer, the BPAOnt ontology instantiation layer, concerned with conceptualising the Riva business process architecture and the associated business process models. The bottom layer, which is the software service identification layer, concerned with the semantic identification of the service-oriented architecture candidate software services and their associated capabilities. In this layer, RPA clusters were used to describe the derived candidate software service. Ontologies were used in order to support addressing the semantic representation. However, the BPAOntoSOA framework has two limitations. First, the derived candidate software services are identified without considering the business goals. Second, the desired quality of service requirements that constrain the functionality of the software services are absent. This research is concerned with resolving these two limitations within the BPAOntoSOA framework. In this research, the original BPAOntoSOA framework has been extended into the GQ-BPAOntoSOA framework. A new semantic-based layer has been added into the two original layers. The new layer is concerned with conceptualising the goal- and quality- oriented models in order to address their absence in the original BPAOntoSOA framework. The new layer is called the GQOnt ontology instantiation layer. This extension has highlighted the need for aligning the models within the original BPAOnt intonation layer with the ones in the new layer. This is because the BPAOnt was the base for the identification of the candidate software services and capabilities. Therefore, a novel alignment approach has been proposed in order to address this need. Also, the original service identification approach is refined in order to adapt with the integration of goals and quality requirements.The GQ-BPAOntoSOA framework, which is a goal-based and quality-linked extended BPAOntoSOA framework, has been evaluated using the Cancer Care Registration process. This is the same case study used in the evaluation of the BPAOntoSOA framework. And this is required in order to investigate the implication of integrating goals and quality requirements into the pre-existing BPAOntoSOA framework-driven candidate software services. This has shown that: (1) the GQOnt ontology does not only contribute to the extension of the BPAOntoSOA framework, yet it also contributes to providing a semantic representation of a business strategy view for an organisation. The GQOnt ontology acts as an independent repository of knowledge in order to have an early agreement between stakeholders with regard to business goals and quality requirements. The semantic representation could be reused for different purposes with respect to the needs. (2) the alignment approach has bridged the gap between goal-oriented models and Riva-based business process architectures. (3) the Riva business process architecture modelling method and business process models have been enriched with the integration of goals and quality requirements in order to provide a rich representation of business process architecture and process models that reflect an important information for the given organisation. (4) The service identification approach used in the original BPAOntoSOA framework has been enriched with goals and quality requirements. This has affected the identification of candidate software services (clusters) and their capabilities. Also, the derived candidate software services have conformed to service-oriented architecture principles. Accordingly, This research has bridged the gap between the BPAOntoSOA framework and the business goals and quality requirements. This is anticipated to lead to highly consistent, correct and complete software service specifications

QUALITY MANAGEMENT OF HOTEL INFORMATION SYSTEM

An information system is the basis of a hotel as a business system. Its role is to improve the processes involved in performing, managing and strategically planning business operations. It enhances the intangible features of services and increases process and service quality through improvements and innovations. As a business system, a hotel consists of a number of interrelated subsystems. A feature of modern hotel operations is the existence of an integrated hotel information system through the use of computers. This system comprises several components (Hardware, Software, Orgware, Lifeware, Netware and Dataware) that must all possess the same level of quality. Only by continuously analysing the quality and alignment of all components is it possible to gain insight into the global quality of a hotel information system and to ensure a more efficient management process. This paper presents the results of a survey conducted among 72 hotel managers from Croatia concerning the importance of the individual components of a hotel information system

ITIL Adoption In Healthcare: A Study Of Process Impact At A New England Hospital A Study Of Process Impact At A New England Hospital

This is a study of how adopting Information Technology Infrastructure Library (ITIL) at a New England hospital impacted service management. The New England hospital began the adoption of ITIL by changing three existing ad-hoc processes to standardized processes following ITIL best practices. Those processes were knowledge management, software management and incident management. This study shows the impact on the quality of IT services and IT/business alignment, and the barriers faced during the adoption project. Using a qualitative methodology through action research, the study found the adoption of ITIL had a positive impact on service management. There is limited academic research regarding adoption of Information Technology Infrastructure Library by healthcare organizations, therefore this study has important implications for healthcare organizations, in general

Lightweight framework for quality assurance in SMEs

Based on their business needs, many software Small and Medium Enterprises (SMEs) differentiate through the high quality of their deliverables, compliancy with standards and alignment with engineering best practices. This paper explains how an SME in that context, successfully used a lightweight framework based on premises like self-assessment, tailoring, automation and positive peer pressure that assured a high level of service quality while removing the implied costs that would be derived from implementing a Quality Assurance (QA) department. Theframework aligned with the company’s agile processes allowing teams, through the implementation of short iterations, to assess their compliancy with a tailored quality baseline and make reviews with the help of cross-teams QualityReviewers. The result was a low cost framework that helped to grow factors like overall process quality while increasing quality perceived from the customer.Sociedad Argentina de Informática e Investigación Operativ

Towards Information Systems Design for Value Webs

In this paper we discuss the alignment between a business model of a value web and the information systems of the participating companies needed to implement the business model. Traditional business-IT alignment approaches\ud focus on one single company, but in a value web we are dealing with various independent businesses. Since a value web is actually a web of services, delivered by IT systems owned by different companies, to ensure alignment we need to\ud specify the services and their properties and then map them on the available IT support in the different companies. Such mappings have to be evaluated in terms of their impact on the profitability of participating in the value web of the different companies. We propose techniques to map services to IT support and show how to do commercial trade-offs

Value-Based Business-IT Alignment in Networked Constellations of Enterprises

Business-ICT alignment is the problem of matching ICTservices with the requirements of the business. In businesses of any significant size, business-ICT alignment is a hard problem, which is currently not solved completely. With the advent of networked constellations of enterprises, the problem gets a new dimension, because in such a network, there is not a single point of authority for making decisions about ICT support to solve conflicts in requirements these various enterprises may have. Network constellations exist when different businesses decide to cooperate by means of ICT networks, but they also exist in large corporations, which often consist of nearly independent business units, and thus have no single point of authority anymore. In this position paper we discuss the need for several solution techniques to address the problem of business-ICT alignment in networked constellations. Such techniques include: -RE techniques to describe networked value constellations requesting and offering ICT services as economic value. These techniques should allow reasoning about the matching of business needs with available ICT services in the constellation. - RE techniques to design a networked ICT architecture that supports ICT services required by the business, taking the value offered by those services, and the costs incurred by the architecture, into account. - Models of decision processes about ICT services and their architecture, and maturity models of those processes.The techniques and methods will be developed and validated using case studies and action research

IT-Business strategic alignment in influencing sustainable competitive advantage in Jordan: Structural Equation Modelling (SEM) approach

In many review articles or studies, the researchers have encouraged further exploration on the causal links between Information Technology (IT) investments and a firm’s sustainable competitive advantage.The outcomes of empirical studies have been inconclusive, which is to a certain extent due to the omission of IT-business strategic alignment.Indeed, strategic alignment has emerged as one of the most important issues facing business and IT executives all over the world. This paper reports on the empirical investigation of the success factors, which consist of leadership, structure and process, service quality, and values and beliefs, which are representative of the culture gap between IT strategy and business strategy.A questionnaire survey among 200 IT managers was carried out and 172 data sets were collected.This represented a 86% response rate. After a rigorous data screening process including outliers, normality, reliability and validity, 172 data sets were ready for structural equation modelling (SEM) analysis. Confirmatory Factor Analysis (CFA) was performed to examine the composite reliability, convergent validity and goodness of fit of the individual constructs and measurement models. The revised structural model demonstrates the relationships between all the four exogenous variables and IT-business strategic alignment, and all the four exogenous variables and sustainable competitive advantage. In addition, regarding the revised model there are two mediating effects of strategic alignment in the relationship between leadership, structure and process, service quality, values and beliefs, and sustainable competitive advantage

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

Competences of IT Architects

The field of architecture in the digital world uses a plethora of terms to refer to different kinds of architects, and recognises a confusing variety of competences that these architects are required to have. Different service providers use different terms for similar architects and even if they use the same term, they may mean something different. This makes it hard for customers to know what competences an architect can be expected to have.\ud \ud This book combines competence profiles of the NGI Platform for IT Professionals, The Open Group Architecture Framework (TOGAF), as well as a number of Dutch IT service providers in a comprehensive framework. Using this framework, the book shows that notwithstanding a large variety in terminology, there is convergence towards a common set of competence profiles. In other words, when looking beyond terminological differences by using the framework, one sees that organizations recognize similar types of architects, and that similar architects in different organisations have similar competence profiles. The framework presented in this book thus provides an instrument to position architecture services as offered by IT service providers and as used by their customers.\ud \ud The framework and the competence profiles presented in this book are the main results of the special interest group “Professionalisation” of the Netherlands Architecture Forum for the Digital World (NAF). Members of this group, as well as students of the universities of Twente and Nijmegen have contributed to the research on which this book is based
