Study and Comparison of Adaptation Mechanisms for Performance Enhancements of Mobile Web Service Consumption

In: Sixth IEEE World Congress on Services (SERVICES 2010); Miami, USA

Category: Proceedings

Abstract

Mobile Web services lie on the intersection of two big IT trends, namely Service-oriented Architectures (SOA) and mobile applications. So, their usage is likely to expand dramatically in the next years. However, the heavyweight nature of service-orientation in terms of the messaging-overhead that is necessary in order to achieve interoperability and loose-coupling comes in contrast with the lightweight nature of mobile devices and with the need to transmit wirelessly as few data as possible. This study categorizes the mechanisms that have been designed in order to bridge this gap, provides comparisons, discusses the results of related experiments, and introduces the future scenario in which the insights of the study can be exploited.

Enhancing Availability with Self-Organization Extensions in a SOA Platform

In: Fifth International Conference on Internet and Web Applications and Services (ICIW 2010); Barcelona, Spain

Category: Proceedings

Abstract

The availability and reliability of Service-oriented architectures (SOA) depends on two factors: On the one hand, the availability and reliability of the services that provide a certain business functionality and on the other hand the services that make up the underlying SOA platform. For platforms that are supposed to form the core of mission-critical service-oriented applications, this implicates the need for mechanisms that can regulate the reliability- and availability-levels of the core services in changing conditions. In this paper, we discuss open questions about what kind of monitoring functionalities and service replication mechanisms should be integrated in SOA infrastructures. Therefore, the integration of concepts from peer-to-peer (P2P) computing is proposed: We present a self-organization extension that can improve the availability of the core services of SOA infrastructures, and we provide an experiment-based evaluation, showing some of the benefits that this extension can have in a critical scenario. The concepts are prototypically implemented as extensions of Apache Tuscany, which is a realization of the Service Component Architecture (SCA) standard.

Optimizing Service Selection for Probabilistic QoS Attributes

In: 5th International Conference on Software and Data Technologies (ICSOFT 2010); Athen, Griechenland

Category: Proceedings

Abstract

The service selection problem (SSP) - i.e., choosing from sets of functionally equivalent services in order to fulfill certain business process steps based on non-functional requirements - has frequently been addressed in literature considering deterministic values for the Quality of Service (QoS) attributes. However, the usage of deterministic values does not reflect the uncertainty about the actual value of an attribute during execution, thus ignoring the risk of QoS violations. In the paper at hand, a simulative step, based on stochastic QoS attributes, is performed as complement for optimally solving the SSP using linear programming methods. With this two-step approach, uncertainties in the selected set of services can be explicitly revealed and addressed through repeated selection steps, thus allowing to prevent the violation of QoS restrictions much more effectively.

The Joint Impact of Service-Oriented Architectures and Business Process Management on Business Process Quality: An Empirical Evaluation and Comparison

In: Forthcoming in: Information Systems and e-Business Management Journal (ISeB); Springer, Berlin

Category: Publications in scientific journals

Abstract

What is the interplay between business process management (BPM) and service-oriented architecture (SOA) in achieving high business process quality? In this paper, we empirically investigate the impact of both SOA and BPM on business process quality in terms of straight-through processing, business-to-business integration, quality control, as well as standardization and consolidation of business processes. For the empirical evaluation of our model, we use the data of 157 German service firms. The results show that the SOA paradigm has still received rather low adoption rates in the industry. However, SOA, BPM, and related information technologies have a direct positive impact on business process quality and the analysis provides evidence for the complementarities of BPM and SOA since interaction effects between them have an additional significant impact on business process quality. Consequently, firms having adopted SOA can more effectively apply BPM.

LOG4SWS.KOM: Self-Adapting Semantic Web Service Discovery for SAWSDL

In: IEEE 2010 Fourth International Workshop of Software Engineering for Adaptive Service-Oriented Systems (SEASS '10) at 2010 IEEE 6th World Congress on Services (SERVICES 2010); Miami, FL

Category: Proceedings [Find it]

Abstract

In recent years, a number of approaches to semantic Web service matchmaking have been proposed. Most of these proposals are based on discrete and thus relatively coarse Degrees of Match (DoMs). However, different basic assumptions regarding the generalization and specialization of semantic concepts in ontologies and their subsequent rating in matchmaking exist. Hence, most matchmakers are only properly suitable if these assumptions are met. In this paper, we present an approach for mapping subsumption reasoning-based DoMs to a continuous scale. Instead of determining the numerical equivalents of the formerly discrete DoMs manually, these values are automatically derived using a linear regression model. This permits not only easy combination with other numerical similarity measures, but also allows to adapt matchmaking to different basic assumptions. These notions are implemented and tested in LOG4SWS.KOM -- a matchmaker for SAWSDL that provides very good evaluation results with respect to Information Retrieval metrics such as precision and recall.

The Future of the European Post-Trading System - A Delphi Study on the Future of the European Post-Trading System in the Light of Globalization and the Financial Crisis

In: Ibidem-Verlag; Hannover

Category: Book

Abstract

The European post-trading system has changed significantly in the last years and is currently facing enormous challenges, e.g. due to the financial crisis, stricter regulation of financial markets, globalization, and the automation of securities processing. Until now, a systematic assessment of the European post-trading industry is missing in academic literature. Using the Delphi methodology, this study among 158 experts from different areas of the post-trading industry aims to develop a joint and coherent view of what the European post-trading system will look like in the future. It identifies measures for the improvement of the post-trading system and the most important issues concerning risk management and information technologies within this industry.

Design Science in Research Cooperations with the Industry: Findings from three Prototyping Projects

In: DESRIST 2010: 5th International Conference on Design Science Research in Information Systems and Technology; St. Gallen, Switzerland

Category: Proceedings

Abstract

A challenge that IS researchers face in general is to combine the goals of generating new scientific knowledge while at the same time producing practically relevant research results, e.g., in the form of IT artefacts. To combine rigor and relevance, researchers and practitioners need to collaborate to develop and employ methods that enable both the systematic generation of scientific insights and the knowledge exchange between academia and industry. In this paper, we present the findings of a research project where we entered into an industry-academic collaboration with the financial services industry involving three software development and implementation projects. We adopted a design science research approach to accompany the project and to guide the scientific discovery process. In the course of our research process we developed an innovative research model that integrates our experiences from the research project with existing design science research models.

Assessing Project Effort in Requirements Engineering: A Report on Design Research in Progress

In: DESRIST 2010: 5th International Conference on Design Science Research in Information Systems and Technology HERBERT A. SIMON BEST PAPER AWARD for the best paper of the conference; St. Gallen, Switzerland

Category: Proceedings

Abstract

In this paper we report on our design research in progress, where we have developed an artifact that assesses project effort resulting from requirements. Based on models used in the goal-oriented requirements engineering method KAOS, the artifact measures system size via function point analysis and analyzes system complexity via structural analysis. In addition, we provide theoretical explanations and empirically validate how size and structural complexity affect project effort. Overall effort depends on counted functions that must be transformed, since software development can be regarded as a transformation process where size matters. Structural complexity matters as well, since software development is also a complex problem, where effort spent depends on the structure of the problem. Insights from empirical evaluation in three software development projects are encouraging, wherefore we believe that the artifact appropriately assesses project effort. Furthermore, our artifact increases the utility of KAOS by providing additional information on project effort.

Because Effort Matters! - A Mapping Model for Assessing Project Effort in Requirements Engineering

In: Business & Information Systems Engineering (2:3), pp. 165-173

Category: Publications in scientific journals

Abstract

Project effort is critical for the success of software development projects. It has a major impact on whether constraints in time and budget can be complied with. But although requirements affect project effort, requirements engineering (RE) methods are not capable of assessing project effort. In this paper, we present our mapping model for assessing project effort (MMAPE). MMAPE incorporates into RE the assessment of project effort resulting from requirements for software development projects. It maps semantics of the RE method KAOS onto structures that are counted in function point analyses. We applied MMAPE in a case study on a software development project within a large financial institution. The validity of MMAPE is supported, since we found throughout consistent statements between information provided by MMAPE and data gathered from the case.

Psychological Contract Violation in IT Megaprojects in the Context of Public Private Partnerships – The German TollCollect Case

In: Proceedings of the 18th European Conference on Information System (ECIS 2010); Pretoria, South Africa

Category: Proceedings

Abstract

Prior research in the context of public private partnerships has mainly focused on organizational and risk management aspects. Because there is a growing number of IT megaprojects in the context of public private partnerships, recent work concentrates on the explanation of the relationship between public and private partners and the success factors for these relations. However, we still have a lack of understanding on the causes and consequences for IT megaproject failure in the context of public private partnerships. In this exploratory, qualitative single-case study from the German TollCollect IT megaproject we draw on findings from the psychological contract theory to explain psychological contract violation as a threat to IT megaproject success. Our research model suggests that the management of common understanding and expectations, moderated by political and public pressure of a public-private environment, affects the stability of the psychological contract and therefore the success of an IT megaproject in the context of public private partnerships.

Conflict as Manifestation of Culture in Global IS Outsourcing Relationships

In: Proceedings of the 18th European Conference on Information System (ECIS 2010); Pretoria, South Africa

Category: Proceedings

Abstract

The objective of this paper is to propose a new way of analyzing culture in global IS outsourcing relationships. Previous research in IS has focused on the analysis of values, beliefs, customs, and other elements of culture whereas other inherent characteristics of culture, such as its dynamic and subjective nature, have been widely ignored. Hence, we suggest analyzing culture and identity in relation to action thereby accounting in more detail for the above mentioned characteristics. In particular, we develop a conceptual model describing the relationship between social identity and conflict in global IS outsourcing relationships. Propositions are derived from social identity and inter-personal conflict theory. The concept of cognitive flexibility (derived from cultural intelligence theory) is introduced as a moderator variable, influencing the relationship between social identity and inter-personal conflict. The conceptual model developed in this paper makes a theoretical contribution to the global IS outsourcing domain and serves as a basis for future empirical research.
