In dieser Arbeit wurde die neue Methode OpenProposal zur asynchronen Anwenderbeteiligung in Software-Projekten entwickelt und im Rahmen von vergleichenden Fallstudien evaluiert. Kern der Methode stellt ein Annotationssystem zur asynchronen Erstellung und Bearbeitung von Anwenderbeiträgen dar....

The modelling of B2B scenarios focuses on conversations between key partners to establish a common business context for their collaboration. With the prevalence of Web services, attention has turned to service choreographies as a means of message exchange ordering between collaborating...

Admission controls, such as trunk reservation, are often used in loss networks to optimise their performance. Since the numerical evaluation of performance measures is complex, much attention has been given to finding approximation methods. The Erlang Fixed-Point (EFP) approximation, which is...

Management are keen to maximize the life span of an information system because of the high cost, organizational disruption, and risk of failure associated with the re-development or replacement of an information system. This research investigates the effects that various factors have on an...

BACKGROUND: Prediction e.g. of project cost is an important concern in software engineering. PROBLEM: Although many empirical validations of software engineering prediction systems have been published, no one approach dominates and sense-making of conflicting empirical results is proving...

Finding effective techniques for the early estimation of project effort remains an important — and frustratingly elusive — research objective for the software development community. We have conducted an empirical study of 21 real time projects for a major software developer. The study...

Es wird das Software Framework JStatCom vorgestellt, welches die Enwicklung von leistungsfähigen grafischen Benutzerschnittstellen für Daten-basierte Analysemethoden wesentlich vereinfacht, wobei der Schwerpunkt auf Methoden der Ökonometrie, insbesondere der Zeitreihenanalyse liegt. Das...

A new method for making software is stealthily gaining ground in the computer industry, offering a promise of better, cheaper software and the empowerment of the user. The open source movement could revolutionize the software industry...if it succeeds. Open source means software that you are...

Electricity has become a integral part of life during the nineteenth and twentieth century. As a society we have become more reliant on electric energy and it is consideredan essential service by the majority of customers. As such electric utilities are under increasing pressure to provide a...

[Abstract}: Assessment-based Software Process Improvement (SPI) programs such as the Capability Maturity Model (CMM), Bootstrap, and SPICE (ISO/IEC 15504) are based on formal frameworks and promote the use of systematic processes and management practices for software development. These...
