Due to rapidly changing technologies and business contexts, many products and services are developed under high uncertainties. It is often impossible to predict customer behaviors and outcomes upfront. Therefore, product and service developers must continuously find out what customers want, requiring a more experimental mode of management and appropriate support for continuously conducting experiments. We have analytically derived an initial model for continuous experimentation from prior work and matched it against empirical case study findings from two startup companies. We examined the preconditions for setting up an experimentation system for continuous customer experiments. The resulting RIGHT model for Continuous Experimentation (Rapid Iterative value creation Gained through High-frequency Testing) illustrates the building blocks required for such a system and the necessary infrastructure. The major findings are that a suitable experimentation system requires the ability to design, manage, and conduct experiments, create so-called minimum viable products or features, link experiment results with a product roadmap, and manage a flexible business strategy. The main challenges are proper, rapid design of experiments, advanced instrumentation of software to collect, analyse, and store relevant data, and integration of experiment results in the product development cycle, software development process, and business strategy. This summary refers to the article The RIGHT Model for Continuous Experimentation, published in the Journal of Systems and Software [Fa17].
First International Workshop on Hybrid dEveLopmENt Approaches in Software Systems Development
(2017)
A software process is the game plan to organize project teams and run projects. Yet, it still is a challenge to select the appropriate development approach for the respective context. A multitude of development approaches compete for the users’ favor, but there is no silver bullet serving all possible setups. Moreover, recent research as well as experience from practice shows companies utilizing different development approaches to assemble the bestfitting approach for the respective company: a more traditional process provides the basic framework to serve the organization, while project teams embody this framework with more agile (and/or lean) practices to keep their flexibility. The first HELENA workshop aims to bring together the community to discuss recent findings and to steer future work.
The ability to develop and deploy high-quality software at a high speed gets increasing relevance for the comptetitiveness of car manufacturers. Agile practices have shown benefits such as faster time to market in several application domains. Therefore, it seems to be promising to carefully adopt agile practices also in the automotive domain. This article presents findings from an interview-based qualitative survey. It aims at understanding perceived forces that support agile adoption. Particularly, it focuses on embedded software development for electronic control units in the automotive domain.
Software and system development faces numerous challenges of rapidly changing markets. To address such challenges, companies and projects design and adopt specific development approaches by combining well-structured comprehensive methods and flexible agile practices. Yet, the number of methods and practices is large, and available studies argue that the actual process composition is carried out in a fairly ad-hoc manner. The present paper reports on a survey on hybrid software development approaches. We study which approaches are used in practice, how different approaches are combined, and what contextual factors influence the use and combination of hybrid software development approaches. Our results from 69 study participants show a variety of development approaches used and combined in practice. We show that most combinations follow a pattern in which a traditional process model serves as framework in which several fine-grained (agile) practices are plugged in. We further show that hybrid software development approaches are independent from the company size and external triggers. We conclude that such approaches are the results of a natural process evolution, which is mainly driven by experience, learning, and pragmatism.
The digital transformation of the automotive industry has a significant impact on how development processes need to be organized in future. Dynamic market and technological environments require capabilities to react on changes and to learn fast. Agile methods are a promising approach to address these needs but they are not tailored to the specific characteristics of the automotive domain like product line development. Although, there have been efforts to apply agile methods in the automotive domain for many years, significant and widespread adoptions have not yet taken place. The goal of this literature review is to gain an overview and a better understanding of agile methods for embedded software development in the automotive domain, especially with respect to product line development. A mapping study was conducted to analyze the relation between agile software development, embedded software development in the automotive domain and software product line development. Three research questions were defined and 68 papers were evaluated. The study shows that agile and product line development approaches tailored for the automotive domain are not yet fully explored in the literature. Especially, literature on the combination of agile and product line development is rare. Most of the examined combinations are customizations of generic approaches or approaches stemming from other domains. Although, only few approaches for combining agile and software product line development in the automotive domain were found, these findings were valuable for identifying research gaps and provide insights into how existing approaches can be combined, extended and tailored to suit the characteristics of the automotive domain.
Seit über 50 Jahren dominiert die neoklassische Kapitalmarkttheorie unser Verständnis für die Abläufe an Finanzmärkten. Sie hat eine Vielzahl von Theorien und Konzepten (z.B. Portfoliotheorie, Capital Asset Pricing Model oder Value-at-Risk) hervorgebracht und basiert auf der Annahme eines streng rationalen Homo Oeconomicus.
Das vorliegende Buch möchte Praktikern die Türe öffnen zu einer neu entstehenden, verhaltenswissenschaftlichen Sicht auf die Finanzmärkte, in der ein realitätsnäherer Homo Oeconomicus Humanus an den Märkten agiert. Er setzt bei der Entscheidungsfindung begrenzt rationale Heuristiken ein und lässt sich von emotionalen Einflüssen lenken.
Die Autoren schlagen zunächst den Bogen von der neoklassischen Sicht der Finanzmärkte zur Behavioral Finance. Anschließend werden spekulative Blasen, von der Tulpenmanie bis zur Subprime Hypothekenblase, als Anzeichen für begrenzte Rationalität an Finanzmärkten ausführlich vorgestellt. Danach stehen die Heuristiken bei Anlageentscheidungen an Wertpapiermärkten im Vordergrund. Die dadurch ausgelösten Verzerrungen werden ntsprechend ihrer Risiko-/Renditeschädlichkeit im Rahmen des RRS-Index® eingeordnet. Abschließend werden Beispiele für die Anwendung der Behavioral-Finance-Erkenntnisse im Wealth Management und Corporate Governance diskutiert und es wird ein Blick auf aktuelle Entwicklungen der Neuro-Finance und Emotional Finance geworfen.
In dieser Auflage neu hinzugekommen ist Financial Nudging, eine besonders vielversprechende Anwendung von Behavioral Finance-Erkenntnissen.
Afrika ist aufgrund überdurchschnittlicher Wirtschaftswachstumsraten und als die weltweit letzten unbearbeiteten Märkte seit einigen Jahren ein populäres Thema der Wirtschaft. Deutsche Unternehmen sind allerdings mit ihrem Engagement auf den afrikanischen Märkten sehr zurückhaltend. So schwankt der Anteil der deutschen Exporte nach Afrika an den deutschen Gesamtexporten seit zehn Jahren um die zwei Prozent; betrachtet man nur Subsahara‐Afrika, so waren es sogar nur 0,5 % in 2014 (Allafi und Koch 2015, S. 3). Bezüglich der Direktinvestitionen (nur Beteiligungskapital, ohne Direktinvestitionskredite) spielt Afrika eine noch geringere Rolle mit nur 1,5 % aller deutschen Investitionen in 2014, wobei hiervon so gut wie alle nach Nordafrika und Südafrika geflossen sind (Deutsche Bundesbank 2015, S. 12 f.). Neben den Standardgründen wie beispielsweise politischen Risiken, schlechter Infrastruktur, schwacher institutioneller Rahmenbedingungen und Governance‐Problemen (vgl. zum Beispiel World Bank 2016a), ist ein gängiges Markteintrittsproblem die fehlende Verfügbarkeit von lokalen Partnern in den Bereichen Vertrieb, Logistik und teilweise auch Produktion (vgl. zum Beispiel Carlowitz und Röndigs 2016). Aktuell ist ein Markteintritt in Afrika ohne lokalen Partner aufgrund der völlig anderen und schwierigen Rahmenbedingungen fast unmöglich.
Incubators in multinational corporations : development of a corporate incubator operator model
(2017)
This paper analyzes the components of a corporate incubator operator model in multinational companies. Thereby, three relevant phases were identified: pre incubation, incubation, and exit. Each phase contains different criteria that represent critical success factors for a corporate incubator, which are based on theoretical findings and lessons learned from practice. During the pre-incubation phase companies should define their need for a corporate incubator, the origin of ideas and the selection criteria for incubator tenants. The actual phase of incubation refers to the incubator program, which should be flexible with respect to each tenant. Furthermore, resource allocation plays an important role during the incubator program. Exit options after a successful incubation differ according to internal ideas and external start-ups, as well as the objective of the incubator. The research is based on a comprehensive screening of existing incubator literature and a qualitative content analysis of statements from eight experts of international corporate incubators.
Gallium nitride high electron mobility transistors (GaN-HEMTs) have low capacitances and can achieve low switching losses in applications where hard turn-on is required. Low switching losses imply a fast switching; consequently, fast voltage and current transients occur. However, these transients can be limited by package and layout parasitics even for highly optimized systems. Furthermore, a fast switching requires a fast charging of the input capacitance, hence a high gate current.
In this paper, the switching speed limitations of GaN-HEMTs due to the common source inductance and the gate driver supply voltage are discussed. The turn-on behavior of a GaN-HEMT is simulated and the impact of the parasitics and the gate driver supply voltage on the switching losses is described in detail. Furthermore, measurements are performed with an optimized layout for a drain-source voltage of 500 V and a drain-source current up to 60 A.
A device including a first and second monitoring unit, the first monitoring unit detecting a first voltage potential and the second monitoring unit detecting a second voltage potential, the monitoring units comparing the first voltage potential and the second voltage potential to the value of the supply voltage and activate a control unit as a function of the comparisons, the control unit determining a switching point in time of a second power transistor, and an arrangement being present which generates current when the second power transistor is being switched on, the current changing the first voltage potential, and the control unit activates a first power transistor when the first voltage potential has the same value as the supply voltage, so that the first power transistor is de-energized.
