Organizational Outsourcing Readiness – Empirically Investigating the Role of Client’s IT Capability, Knowledge, and Alignment of Outsourcing
In: Ibidem Verlag
Category: Dissertation thesis
AbstractHow can prospective outsourcing clients prepare their internal organizational workflows to meet the challenges associated with an outsourcing venture with little penalty in time, cost, and effort? Along this guiding question, the author empirically investigates the ways in which several factors of the client company's internal organizational context affect the outcomes of their outsourcing efforts. The investigated factors represent the client's IT capability, the explicit knowledge in form of business process documentation available within the company, and the level of alignment between the client's IT and business domains. Based on qualitative and quantitative empirical data, S. F. Martin demonstrates that each of these client-specific factors has a significant inter-organizational impact, affecting the quality of the relationship between client and provider, the vendor’s performance, and outsourcing success.

Integrating Semantic Web Services and Matchmaking into ebXML Registry
In: Proceedings of the Fourth International Workshop SMR2 2010 on Service Matchmaking and Resource Retrieval in the Semantic Web; Shanghai, China
Category: Proceedings
Abstract While the "Universal Description, Discovery and Integration" (UDDI) service registry standard has drawn great attention by the research community, it has not been widely adopted by the software industry. Objections towards UDDI include technical as well as conceptional arguments. Being an official ISO standard and providing a number of features UDDI is missing, "Electronic Business using Extensible Markup Language" (ebXML) Registry could be an adequate alternative for the implementation of service registries and/or repositories. However, little work has been done regarding the integration of Semantic Web Services (SWS) into ebXML Registry. In this paper, we present a solution extending the ebXML Registry by capabilities to handle and provide SWS. This includes a concept for the integration of SWS into ebXML Registry as well as a prototypical implementation using SAWSDL and the open source framework freebXML.

Web Service Discovery Based on Semantic Information - Query Formulation and Adaptive Matchmaking
In: Technische Universität Darmstadt; Darmstadt
Category: Dissertation thesis [Find it]
AbstractService-oriented Computing introduces a range of possible applications spanning from the combination of Web services in software mashups to the design and implementation of entire IT system landscapes following the paradigm of Service-oriented Architectures. The discovery of services which provide a desired capability is one of the basic operations in Service-oriented Computing and is deemed to be one of the grand challenges in Web service research. This applies in particular to scenarios with a large number of service offers, where it is desirable to automate the discovery process to some degree. Service discovery is based on the description of service components, e.g., interfaces or operations. As the syntactic description of a Web service is often imprecise, semantic Web services are considered to play a decisive role in the facilitation of service discovery. In this context, the application and utilization of semantic information in service discovery concerns the ability of service providers to describe services, the ability of requesters to specify requirements, and the effectiveness of the service matchmaker, i.e., an algorithm that takes into account a request and finds the best fitting services from a set of service offers. Matchmaking research focuses on the selection of the necessary elements from a service description, similarity metrics, and the combination of the resulting similarity values. This thesis provides several contributions to the improvement and ease of service discovery based on semantic information. The main contributions are made in the fields of service matchmaking and query formulation. Regarding the first-mentioned contribution, two approaches to matchmaking for semantic Web services are presented. The first of which, LOG4SWS.KOM, is based on "classical" subsumption matching and introduces an innovative way to weight and combine different matching degrees. LOG4SWS.KOM is self-adaptive to different basic assumptions regarding the semantic concepts applied in a service description. This includes different presumptions regarding what a semantic annotation on a distinct service abstraction level actually denotes as well as the meaning of different subsumption relationships between semantic concepts. LOG4SWS.KOM is applied to different abstraction levels of a service description, which may not necessarily be completely described using semantic information. Hence, the matchmaker includes a linguistic-based fallback strategy, triggering the need to incorporate syntactic information. The second matchmaker, COV4SWS.KOM, deviates from logic-based similarity measurement and applies methods from the field of relatedness measurement of semantic concepts in ontologies. This way, COV4SWS.KOM allows more fine-grained relationships than conventional subsumption matching-based approaches. Additionally, COV4SWS.KOM introduces the adaptation to varying quality and usefulness of syntactic descriptions and semantic annotations at different abstraction levels of a service description. Both matchmakers are implemented for SAWSDL and provide, to the best of our knowledge, the best matchmaking results for this Web service standard regarding Information Retrieval metrics, so far. Regarding the second focus of this thesis - query formulation for semantic Web service discovery - an extensive analysis of requirements towards a unified service query formalism has been conducted. Based on this analysis, two different approaches to query formulation for semantic Web services have been designed, developed, and implemented. The first is a lightweight approach making use of already existing standards and technologies: Here, a slightly extended SPARQL syntax for SAWSDL-based service descriptions is integrated into UDDI. However, the usage of existing standards imposes some constraints, as especially SPARQL has not been explicitly designed for query formulation for semantic Web services. Hence, a second, more advanced approach, has been implemented, where a distinct, SPARQL-based query language is conceptualized and integrated in a service registry. This language - SWS2QL - allows a service requester to address different service abstraction levels, incorporate and parameterize matchmakers, define thresholds, etc., leading to a sophisticated, fine-grained definition of service requests. Even though the corresponding proof of concept implementation makes use of ebXML as service registry standard and SAWSDL as service formalism, results can be easily transferred to other registry and service technologies, as the approach is based on abstract service data and query models. This way, a unified service query formalism is provided. Apart from the main contributions, this thesis also provides a general framework based on ebXML, which features the integration of semantic Web service descriptions and different service matchmakers into this registry standard.

Query Languages for Semantic Web Services
In: Service Science - Neue Perspektiven für die Informatik - Proceedings der Informatik 2010, Lecture Notes in Informatics; Leipzig
Category: Proceedings [Find it]
Abstract Even though service discovery is one of the vital steps in Web service invocation, service requests are usually expressed by rather simple means. While syntax-based service descriptions are usually addressed using keyword-based queries, Semantic Web Services are queried using ``perfect'' service descriptions. Hence, a service requester is not able to control the outcome of the discovery process in-depth by specifying similarity ranges or to explicitly state which syntax- and semantic-based parts of a service description should be addressed. In this paper, we present an analysis of current approaches to service request formulation and identify requirements a query formalism for Semantic Web Services should fulfill. Furthermore, we give a brief preview on SWS2QL, a SPARQL-based query language for Semantic Web Services.

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
AbstractMobile 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
AbstractThe 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.

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
AbstractWhat 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.

Category: Proceedings [Find it]
AbstractIn 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.

Category: Proceedings [Find it]
AbstractA 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.

Category: Proceedings
AbstractIn 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.

Category: Publications in scientific journals
AbstractProject 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 [Find it]
AbstractPrior 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
AbstractThe 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.
