enhancing Service Lifecycle management costing as part of Service descriptions
Americas Conference on Information Systems, 2013Co-Authors: Michael Fischbach, Thomas Puschmann, Rainer AltAbstract:Outsourcing of IT and business processes results in an increased exchange of Services. For inter-organizational Service exchange to be successful, the participating network players have to establish unified and thus interoperable means of Service description. An analysis of contemporary approaches identified a deficit of almost all approaches to address monetary aspects of a Service, especially costs. This paper argues that costs are prevalent in almost all stages of a Services' Lifecycle, and thus its' role within Service Lifecycle Management (SLM) is paramount. Recognizing this discrepancy, the paper proposes a basic version of a costing model that allows for a multi-periodic depiction of Service-related costs as part of a Service description. It is modeled and implemented as an extension of USDL, the Unified Service Description Language. A case example from the financial Services industry demonstrates the artifact's applicability.

ECIS - Enhancing Soa With Service Lifecycle Management - Towards A Functional Reference Model
2013Co-Authors: Michael Fischbach, Thomas Puschmann, Rainer AltAbstract:Service-orientation is a paradigm aiming at decomposing monolithic application systems into Services, i.e. functional units that adhere to certain criteria such as standardized interfaces and the ability to be flexibly combined with each other. With the growing importance and diffusion of this paradigm, the management of an increasing number of Services along their Lifecycle (Service Lifecycle Management - SLM) is becoming a success factor. Although comprehensive IT support is not the only ingredient for successfully managing Services, it is a contribution to compensate for the growing complexity. Surprisingly, the topic of software application support in SLM has not yet received systematic coverage in the literature from a functional perspective. Consequently, this paper proposes a functional reference model for SLM and describes the underlying design process. The model supports practitioners in analyzing, designing and implementing software support for SLM. Further it enables to compare and evaluate existing software solutions and as such it supports IT investment decisions. Scientifically the model represents an approach towards designing information systems in the area of SLM. The paper argues that companies should pursue a best-of-breed approach, as there is no single solution available that comprehensively supports the entire Lifecycle. Further, the lack of application support of SLM in practice mainly stems from the absence of integrated solutions and missing knowledge on how to evaluate potential applications.

Service-Lifecycle-Management
WIRTSCHAFTSINFORMATIK, 2013Co-Authors: Michael Fischbach, Thomas Puschmann, Rainer AltAbstract:Service-oriented architectures (SOA) are an intensively discussed architectural paradigm in science and practice. Originally grounding in software modularization efforts, SOA is increasingly part of the discourse on business models. For example, software providers no longer offer their solutions solely as complete packages, but rather allow customers to use them in parts or as a whole on a pay-per-use basis (Software as a Service, Platform as a Service). SOA's contribution within these business models is a flexibility gain obtained by abstracting from the underlying implementation. This abstraction leads to a decomposition of applications into fine-granular Services. For example, a core banking system might offer a credit worthiness check, while a customer relationship management system processes the customer data. However, these applications are frequently based on different SOA models (e.g., SAP, Oracle). Consequently, increasing modularity causes higher complexity, due to heterogeneous Service specifications, Service development processes, Service implementations, and operating models. Adding to this, often several suppliers with heterogenous SOA platforms are involved. Without a dedicated management of Services along their life cycle (Service Lifecycle Management - SLM), additional alignment efforts would be necessary. Thus, the management of Services as well as Service portfolios arising from the modularization of monolithic applications plays an important role. However, SLM approaches are just as heterogeneous as the different applications and their SOA models. The numerous facets exhibit a clear dichotomy between technical and business-oriented approaches. This article suggests an integrated SLM model to overcome this dichotomy.

überbetriebliches Service Lifecycle Management
HMD Praxis der Wirtschaftsinformatik, 2011Co-Authors: Thomas Puschmann, Rainer AltAbstract:Serviceorientierte Architekturen (SOA) sind das gegenwärtige Zielmodell auf der Suche nach Prozessflexibilität. Mit der Verbreitung dieses Architekturkonzepts in der Praxis entsteht jedoch eine erhebliche Komplexität zur Koordination der Services, die sich im überbetrieblichen Kontext weiter erhöht. Unternehmen benötigen Ansätze für das Management ihrer Services über den gesamten Lebenszyklus hinweg von der Spezifikation über die Entwicklung bis hin zum Betrieb. Dieser Beitrag entwickelt auf der Grundlage der Anforderungen von SOA und eines Vergleichs bestehender Ansätze des Application Management ein Rollen- und Prozessmodell für ein überbetriebliches Service Lifecycle Management (SLM). Zwei Fallbeispiele stellen mögliche Geschäftsmodelle für das SLM gegenüber.

Stakeholder Identification and Analysis for Service Lifecycle Management
International Journal of Web Services Research, 2014Co-Authors: Wenge Rong, Yuanxin Ouyang, Kecheng Liu, Zhang XiongAbstract:The convergence of information technology and diverse business requirements is making the organization information systems more complex. Quickly integrating existing systems and developing new applications to serve the requirement of flexible business environments have become a key factor for organizations to gain a competitive edge. To meet this challenge, the concept of Service Oriented Architecture (SOA) has been proposed and widely lauded as an innovative business oriented solution. To better utilize SOA's advantages, several research problems should be attached much importance among which Service Lifecycle management is a notable one, which is one of the critical mechanisms leading to higher Service quality. A large number of Service Lifecycle models have been proposed in the literature while few of them clearly indicate the integration of the Lifecycle processes with stakeholders. In this research, a conceptual stakeholder identification and analysis framework is proposed by which stakeholders are analyzed within different Service Lifecycle stages. It is believed that this method can offer the researchers in the community further insight into Service Lifecycle management from the stakeholder's perspective.

prioritised stakeholder analysis for software Service Lifecycle management
International Conference on Web Services, 2013Co-Authors: Wenge Rong, Yuanxin Ouyang, Kecheng Liu, Zhang XiongAbstract:During the process of building business agility, the concept of Service Oriented Architecture (SOA) is proposed and widely lauded as an innovative business oriented solution. One of the most fundamental components in SOA based applications is a Service, which represents the repeatable business functionalities to help the development of loosely coupled applications. Due to its important role in implementing SOA based applications for achieving dynamic business process, how to build a scalable, reliable Service efficiently has become a vital challenge, while the Service Lifecycle management becomes one of the critical mechanisms to ensure the Service quality. Currently, there are a large number of Service Lifecycle models proposed in the literature to fit their own purposes. However, few of them clearly indicate the integration of the Lifecycle processes with stakeholders. To meet this gap, in this research a conceptual stakeholder analysis framework is proposed to associate the stakeholders with different Lifecycle stages. It is believed that this method is able to offer the researchers in the community further insight into Service Lifecycle management from the stakeholder's perspective.

open challenges for consulting Service Lifecycle management what Service research should learn from software Lifecycle management
IEEE International Conference on Services Computing, 2012Co-Authors: Pietro Mazzoleni, Richard Goodwin, Clay WilliamsAbstract:In the last two decades, research in software engineering has hada focus on software Lifecycle management. Rather than a narrowfocus on programming languages environments and softwaredevelopment, researchers are considering the end-to-end Lifecycleof software, including design, development, deployment, supportand retirement. Business IT consulting has a similar Lifecyclefrom request for proposal, to proposal, delivery, on-goingoperation and retirement. For the past 5 years we have beenworking with IBM Global Business Services to address issues indelivering Business IT Services. From this experience, we'veidentified a number of open challenges and have begun workingon solutions and a platform for addressing these challenges. Weare starting with lessons learned in software Lifecyclemanagement, and building on them to address challengesparticular to Service delivery. For example, like softwareLifecycle management, Services Lifecycle management requiressupport for end-to-end traceability, coordination between peopleworking on related activities and on hand offs between one phaseof a consulting project and the next. In this paper, we enumeratea set of open challenges for Service Lifecycle management. Wesuggest how lessons from software Lifecycle management can beapplied and give a preliminary report on our implementation ofan open architecture environment to support Services Lifecyclemanagement.
