Show/Hide Abstract Betsy - A BPEL Engine Test System (2012)
Simon Harrer Jörg Lenhard
More than five years have passed since the final release of the long-desired OASIS standard of a process language for web service orchestration, the Web Services Business Process Execution Language (BPEL). The aim of this standard is to establish a universally accepted orchestration language that forms a core part of current service-oriented architectures and, because of standardisation, avoids vendor lock-in. High expectations, in academia and practice alike, have been set on it. By now, several fully conformant and highly scalable engines should have arrived in the market. The perception of many however, is that standard conformance in current engines is far from given. It is our aim to shed light on this situation. In this study, we present the tool betsy, a BPEL Engine Test System that allows for a fully-automatic assessment of the standard conformance of a given BPEL engine. We use it to examine the five most important open source BPEL engines available today. Betsy comes with a large set of engineindependent conformance test cases for assessing BPEL standard conformance. This enables us to give a view of the state of the art in BPEL support.
Show/Hide Abstract Skalen zu erlebens- und lernförderlichen Merkmalen der Arbeitsaufgabe (ELMA) (2012)
Andreas Rausch
Mit dem steigenden Interesse an informellen Lernprozessen am Arbeitsplatz stieg in den vergangenen Jahren auch die Anzahl von Fragebogeninstrumenten zur Erfassung von Erleben- und Lernpotenzialen in der Arbeit. Trotz methodologischer Einschränkungen ist die retrospektive Selbstauskunft mittels Fragebogen nach wie vor der populärste empirische Zugang. Einflussfaktoren des Erlebens- und Lernpotenzials werden in der Regel auf Aufgabenmerkmale sowie auf Interaktionsqualitäten zurückgeführt. Im vorliegenden Manual wird der Fragebogen zur Erfassung erlebensund lernförderlicher Merkmale der Arbeitsaufgaben (ELMA) vorgestellt. Das Instrument basiert auf einer Zusammenstellung von Skalen vorliegender Instrumente, Weiterentwicklungen dieser Skalen und Neukonstruktionen durch den Autor.
Boccanegra und das Ende der Geschichte (2012)
Albert Gier
Show/Hide Abstract ENTWICKLUNG – PROFILIERUNG – WACHSTUM. Die Otto-Friedrich-Universität Bamberg von 2000 bis 2010 (2011)
Die Universität veröffentlicht jährlich einen Rechenschaftsbericht, in dem sie Auskunft gibt über die wichtigsten Ereignisse und Neuerungen des betreffenden Haushaltsjahres. Doch was sich in einem längeren Zeitraum an größeren Entwicklungen und übergeordneten Veränderungen ereignet hat, wird darin in der Regel nur andeutungsweise sichtbar. Die Idee hinter der hier vorgelegten Publikation, die den Zeitraum seit dem Jahr 2000 abdeckt, ist daher eher die eines Entwicklungsberichts. Anstelle einzelner Kennzahlen möchten wir die großen Entwicklungslinien nachzeichnen, entlang derer jene Prozesse abgelaufen sind, die zunächst ganz abstrakt beschrieben werden können als Fokussierung, Optimierung, Konzentration und Internationalisierung.
Show/Hide Abstract A Pattern-based Analysis of WS-BPEL and Windows Workflow (2011)
Jörg Lenhard
Orchestration languages are of paramount importance for building composite services in service-oriented architectures. Pattern-based analysis is a method that allows to determine the expressiveness of existing process languages and serves as a means of comparison between different languages. The aim of this study is the analysis and comparison of important languages for building Web Services-based orchestrations, as well as the improvement of the method of pattern-based analysis. The predominant orchestration language today is the Web Services Business Process Execution Language (WS-BPEL) 2.0. This language is a standard that has been implemented by several companies and projects, such as the OpenESB BPEL Service Engine. An additional language is Windows Workflow 4 that is shipped by Microsoft as part of the .NET framework. There are various aspects, represented by pattern catalogs, for which existing languages can be analyzed. This study suggests a methodology for ordering existing pattern catalogs according to their importance for a selected problem domain which is Business-to-Business Integration. It furthermore presents an extensive evaluation of the languages at hand and assesses the degree of support they provide for several of the most important pattern catalogs. These catalogs are the workflow control-flow patterns, the service interaction patterns, the change patterns and the time patterns.
Show/Hide Abstract Management by Objectives-Based Groupware: Requirements for Efficient and Effective Achievements of Objectives (2011)
Sam Tschernitz Tom Gross
This paper is concerned with the challenges arising from the development of a groupware requirement specification for effective and efficient achievement of operative and strategic objectives in mass production industry. To analyze the process by which objectives are achieved, a systematical investigation using document analysis, participant observation, interviews and context scenario analysis was undertaken at a large manufacturing location with over 6 000 coworkers of a multinational automobile supplying company. The results of this in-depth analysis of objective achievement were utilized to develop a detailed requirement specification for a management by objectives groupware for use in mass production industry.
Show/Hide Abstract A Process for Identifying Predictive Correlation Patterns in Service Management Systems (2010)
Werner Zirkel Guido Wirtz
By using the remote functions of a modern IT service management system infrastructure, it is possible to analyze huge amounts of logfile data from complex technical equipment. This enables a service provider to predict failures of connected equipment before they happen. The problem most providers face in this context is finding a needle in a haystack - the obtained amount of data turns out to be too large to be analyzed manually. This report describes a process to find suitable predictive patterns in log files for the detection of upcoming critical situations. The identification process may serve as a hands-on guide. It describes how to connect statistical means, data mining algorithms and expert domain knowledge in the domain of service management. The process was developed in a research project which is currently being carried out within the Siemens Healthcare service organization. The project deals with two main aspects: First, the identification of predictive patterns in existing service data and second, the architecture of an autonomous agent which is able to correlate such patterns. This paper summarizes the results of the first project challenge. The identification process was tested successfully in a proof of concept for several Siemens Healthcare products.
