In a corporation’s financial life “going public” by means of an IPO is probably the single most important decision. It turns a private company into a public one. Our book will provide an inside view of the IPO process. On the one hand, it draws on the insights of an experienced investment banker, who has gone through numerous IPO transactions. On the other hand, it relates the story of an actual IPO through the eyes of a Chief Executive Officer who has taken two of his companies public. This unique double perspective is our book’s defining feature. We do not discuss initial public offerings in a textbook style fashion. What we would like to bring out is a more comprehensive portrayal of a “once-in-a-lifetime” event for most companies and their management, alike.
In this paper a method for the generation of gSPM with ontology-based generalization was presented. The resulting gSPM was modeled with BPMN/BPMNsix in an efficient way and could be executed with BPMN workflow engines. In the next step the implementation of resource concepts, anatomical structures, and transition probabilities for workflow execution will be realized.
Software and system development is complex and diverse, and a multitude of development approaches is used and combined with each other to address the manifold challenges companies face today. To study the current state of the practice and to build a sound understanding about the utility of different development approaches and their application to modern software system development, in 2016, we launched the HELENA initiative. This paper introduces the 2nd HELENA workshop and provides an overview of the current project state. In the workshop, six teams present initial findings from their regions, impulse talk are given, and further steps of the HELENA roadmap are discussed.
Software startups often make assumptions about the problems and customers they are addressing as well as the market and the solutions they are developing. Testing the right assumptions early is a means to mitigate risks. Approaches such as Lean Startup foster this kind of testing by applying experimentation as part of a constant build-measure-learn feedback loop. The existing research on how software startups approach experimentation is very limited. In this study, we focus on understanding how software startups approach experimentation and identify challenges and advantages with respect to conducting experiments. To achieve this, we conducted a qualitative interview study. The initial results show that startups often spent a disproportionate amount of time focusing on creating solutions without testing critical assumptions. Main reasons are the lack of awareness, that these assumptions can be tested early and a lack of knowledge and support on how to identify, prioritize and test these assumptions. However, startups understand the need for testing risky assumptions and are open to conducting experiments.
Context: The current situation and future scenarios of the automotive domain require a new strategy to develop high quality software in a fast pace. In the automotive domain, it is assumed that a combination of agile development practices and software product lines is beneficial, in order to be capable to handle high frequency of improvements. This assumption is based on the understanding that agile methods introduce more flexibility in short development intervals. Software product lines help to manage the high amount of variants and to improve quality by reuse of software for long term development.
Goal: This study derives a better understanding of the expected benefits for a combination. Furthermore, it identifies the automotive specific challenges that prevent the adoption of agile methods within the software product line.
Method: Survey based on 16 semi structured interviews from the automotive domain, an internal workshop with 40 participants and a discussion round on ESE congress 2016. The results are analyzed by means of thematic coding.
Spekulationsblasen ziehen sich wie ein roter Faden durch die Geschichte der Finanzmärkte. Die erste bedeutende und dokumentierte Blase entstand im 17. Jahrhundert in Holland als weit bekannte Tulpenmanie. Weitere sollten in den nächsten Jahrhunderten folgen. Doch wie entstehen diese zumeist euphorischen und schlussendlich panikartigen Marktentwicklungen? Und wie konnte es immer wieder passieren, dass diese von Börsenprofis nicht rechtzeitig erkannt wurden? In diesem Buch stehen die Spekulationsblasen als Anzeichen für wiederkehrende und anhaltende Marktanomalien im Fokus der Betrachtung. Rolf J. Daxhammer und Máté Facsar erklären im ersten Teil die Entstehung und Ursachen für die Bildung von Spekulationsblasen sowie die unterschiedlichen Phasen und Arten. Dabei ist es ihnen besonders wichtig aufzuzeigen, dass diese sowohl positive als auch negative Effekte auf die Volkswirtschaften haben. Anschließend stellen die Autoren die wichtigsten Spekulationsblasen, beginnend mit der Tulpenmanie über die Südseeblase bis hin zu aktuellen Entwicklungen an Finanz- und Immobilienmärkten, vor. Der Leser ist somit in der Lage, typische Eigenschaften der Kapitalmärkte zu verstehen und die Entwicklung historischer Spekulationsblasen auf Basis des Fünf-Phasen-Modells zu erklären und dieses anzuwenden.
This paper reports an analysis of application and impact of FMEA on susceptibility of generic IT-networks. It is not new that in communication system, the frequency and the data transmission rate play a very important role. The rapid increase in miniaturization of electronic devices leads to very sensitivity against electromagnetic interference. Since the IT network with the data transfer rate makes a huge contribution to this development it is very important to monitor their functionality. Therefore, tests are performed to observe and ensure the data transfer rate of IT networks against IEMI. A fault tree model is presented and observed effects during radiation of disturbance on complex system by a HPEM interference sources are described using a continuous and consistent model of the physical layer to the application layer.
Previous studies have reported changes in organizational identities as a result of external or internal triggers. In contrast, we highlight how the paradoxical nature of an organizational identity can influence stability and change that identity. Using the example of Wikipedia, the free online encyclopedia, we show how a "stable state of instability" of the organization´s collective identity is constantly being reproduced. We contribute to the literature on organizational identity by first analyzing a case in which identity change is not triggered by a disruptive event. Second, we show how the paradoxical nature of identity triggers attempts to reconcile contradictions of the paradox, culminating in permanent state of gradual changes of organizational identity. Finally, we exemplify how, as a form of partial organization where volunteers take part in the identity formation process, Wikipedia copes with the tensions that ensue from its collective identity.
