Stakeholder involvement in SOA : analyzing service identification as co-designHadizadeh, Nafiseh January 2012 (has links)
The need for adapting rapidly to IT and business changes, reducing costs, delivering improved functionality of services and better integration push organizations towards service oriented architecture (SOA) adaption. Delivering SOA requires building systems at the business level, not just at the IT level. Delivery of services needs concentration on the business needs first. As people are the most important factors in defining business requirements, processes and making business decisions, their active involvement in SOA adoption is essential. SOA adoption is evolutionary rather than revolutionary; it is not possible to be accomplished without cooperation of stakeholders who have effect on the system. Many organizations fail to deliver SOA since they underestimate the role of key business people in SOA development. In order to evolve SOA successfully from business perspective, stakeholder involvement should be conducted from early phases of SOA when important decisions are made and business processes are defined. Service identification is one of the important and main activities in SOA development. This study therefore focuses on service identification of SOA from a business view and regard to stakeholders. Text analysis and interviews are the method components used in this research. Some aspects covering the importance of service identification in SOA development, role of stakeholders in service identification and role of scenarios in stakeholder involvement have been identified through text analysis. And three interviews with experts within the area have verified the identified aspects. The result shows that co-design is an appropriate strategy for conducting service identification regard to stakeholders in an effective way. Different ideas can be visualized, explored and examined through this perspective and a realistic appropriate solution can be found. The challenges of co-design in addressing SOA benefits are also studied through theoretical and empirical parts of the study, and the result is summarized in a table which shows the strengths and weaknesses of co-design strategy in service identification process in addressing SOA goals. The results are categorized to two forms of service identification, consultant driven service identification and internal staff driven service identification. The result of the study can be a contribution in determining the employment of co-design in service identification considering different situations. / Program: Magisterutbildning i informatik

Previous issue date: 2012-03 / A combinação de Linhas de Produto de Software (LPS) e Computação Orientada a
Serviços (COS) tem recebido atenção de pesquisadores e praticantes, já que uma área
é capaz de solucionar determinados problemas da outra. A junção dessas duas áreas é
chamada de Linha de Produto Orientada a Serviços (LPOS), e tem se mostrado uma área
de pesquisa emergente nos últimos anos.
No contexto da Computação Orientada a Serviços, identificação de serviços é uma das
primeiras atividades para modelagem de uma solução COS, e consiste na determinação
de serviços candidatos. Essa não é uma tarefa trivial, e os erros adquiridos durante a
identificação de um serviço pode propagar-se para as atividades subsequentes do processo
de desenvolvimento orientado a serviços.
Existem diversas propostas para identificação de serviços. Apesar da diversidade, não
existe um método de identificação de serviços capaz de adequar-se a diversos contextos e
necessidades. Considerando a heterogeneidade desses métodos, esta dissertação tem o
objetivo de verificar quais métodos podem ser aplicados em linhas de produto de software,
bem como as vantagens, desvantages e desafios existentes neste campo.
Esta pesquisa utilizou uma abordagem multi-métodos, que combina estudos primários
e secundários a fim de incrementar o corpo de conhecimento em determinada área baseada
nos achados de tal investigação. Desta forma, este trabalho utilizou um método secundário
(revisão sistemática) e dois métodos primários com o intuito de aumentar a confiabilidade
dessa pesquisa.
Além disso, foi realizada uma revisão da literatura a fim de coletar as abordagens
de identificação de serviços existentes, visando propor uma recomendação dos métodos
mais adequados considerando três cenários de LPS: top-down, bottom-up e hybrid. Esta
recomendação foi avaliada através de um estudo de caso com uma linha de produto
de sistemas médicos, usando dois metodos classificados no cenário o qual os sistemas
médicos encontram-se, top-down.
A principal contribuição dessa pesquisa é prover um instrumento que auxilie os
interessados em identificar serviços a escolher um método apropriado, levando em
consideração o cenário SPL a ser aplicado. Os resultados do estudo de caso mostram que
as abordagens de identificação de serviços podem ser aplicadas num contexto de LPS.
Além disso, este métodos facilitam a realização da atividade de identificação. / The combination of Software Product Line (SPL) and Service-Oriented Computing (SOC)
have started to receive attention by researchers and practitioners, since they can address
issues of each other. Putting these two areas together is called Service-Oriented Product
Lines Enginering (SOPLE), presenting itself as an emerging area in the last years.
In the Service-Oriented Computing, service identification is one of the first activities
in the modeling of a SOC solution, that consists of determining candidate services. This
is not a trivial task, and the errors made during the identification can propagate mistakes
to the next activities of the service-oriented development process.
There are several proposals addressing service identification for several contexts.
However, an unified method for identifying services has not yet been reached. Regarding
the heterogeneity of these methods, this dissertation aims to verify which methods can be
applied in the SPL context, the advantages, disadvantages and the existing challenges of
this field.
This research used a multi-method approach that combines primary and secondary
studies in order to increase the availability of empirical knowledge based on the findings
of the investigation. Thus, this work used one secondary method (systematic review) and
two primary methods (survey and case study) to address it.
Furthermore, it was performed a literature review in order to collect all existing
approaches of service identification, aiming to propose a set of decision models that
recommend the most suitable methods according to three SPL scenarios: bottom-up, topdown
and hybrid, onde decision model for each scenario. One of the decision models was
evaluated through a case study in a medical applications domain, using two approaches
classified in the decision model of the top-down scenario.
The main contribution of this research is to provide an instrument that can help the
service identification stakeholders to choose a suitable method, taking consideration of
their SPL scenarios. In addition, these systematic methods facilitate the application of
the identification activity. The case study results evaluated some service identification
approaches and presented evidence that the methods can be applied in SPL.

Supply Chain Event Management – Bedarf, Systemarchitektur und Nutzen aus Perspektive fokaler Unternehmen der ModeindustrieTröger, Ralph 10 November 2014 (has links) (PDF)
Supply Chain Event Management (SCEM) bezeichnet eine Teildisziplin des Supply Chain Management und ist für Unternehmen ein Ansatzpunkt, durch frühzeitige Reaktion auf kritische Ausnahmeereignisse in der Wertschöpfungskette Logistikleistung und -kosten zu optimieren.
Durch Rahmenbedingungen wie bspw. globale Logistikstrukturen, eine hohe Artikelvielfalt und volatile Geschäftsbeziehungen zählt die Modeindustrie zu den Branchen, die für kritische Störereignisse besonders anfällig ist. In diesem Sinne untersucht die vorliegende Dissertation nach einer Beleuchtung der wesentlichen Grundlagen zunächst, inwiefern es in der Modeindustrie tatsächlich einen Bedarf an SCEM-Systemen gibt.
Anknüpfend daran zeigt sie nach einer Darstellung bisheriger SCEM-Architekturkonzepte Gestaltungsmöglichkeiten für eine Systemarchitektur auf, die auf den Designprinzipien der Serviceorientierung beruht. In diesem Rahmen erfolgt u. a. auch die Identifikation SCEM-relevanter Business Services. Die Vorzüge einer serviceorientierten Gestaltung werden detailliert anhand der EPCIS (EPC Information Services)-Spezifikation illustriert.
Abgerundet wird die Arbeit durch eine Betrachtung der Nutzenpotenziale von SCEM-Systemen. Nach einer Darstellung von Ansätzen, welche zur Nutzenbestimmung infrage kommen, wird der Nutzen anhand eines Praxisbeispiels aufgezeigt und fließt zusammen mit den Ergebnissen einer Literaturrecherche in eine Konsolidierung von SCEM-Nutzeffekten. Hierbei wird auch beleuchtet, welche zusätzlichen Vorteile sich für Unternehmen durch eine serviceorientierte Architekturgestaltung bieten.
In der Schlussbetrachtung werden die wesentlichen Erkenntnisse der Arbeit zusammengefasst und in einem Ausblick sowohl beleuchtet, welche Relevanz die Ergebnisse der Arbeit für die Bewältigung künftiger Herausforderungen innehaben als auch welche Anknüpfungspunkte sich für anschließende Forschungsarbeiten ergeben.
