Bereits seit Anfang der 1990er Jahre wird jungen Wissenschaftlern im Vorfeld der Tagung "Wirtschaftsinformatik" ein Doctoral Consortium als unterstützendes Forum angeboten. Diese Einrichtung wurde auch zur größten Internationalen Konferenz der Wirtschaftsinformatik, der WI 2015 in Osnabrück fortgeführt. Dieser Band fasst die zum Vortag ausgewählten Beiträge zusammen.
Nach der Einleitung werden im zweiten Kapitel die zivilrechtlichen, ertrag- und schenkungsteuerrechtlichen Definitionen der Begriffe “Schenkung unter Lebenden” sowie „vorweggenommene Erbfolge“ nach deutschem, österreichischem und schweizerischem Recht sowie das Rechtsinstitut des Nießbrauchs nach deutschem, österreichischem und schweizerischem Zivil- und Gesellschaftsrecht gegenübergestellt. Im dritten Kapitel erfolgt die schenkungsteuerliche Beurteilung der Vermögensübertragung nach deutschem, österreichischem und schweizerischem Schenkungsteuerrecht. Die ertragsteuerliche Beurteilung der Vermögensübertragung nach deutschem, österreichischem und schweizerischem Ertragsteuerrecht erfolgt im vierten Kapitel. Nach den zivilrechtlichen Grundlagen bei grenzüberschreitenden Vermögensübertragungen werden im sechsten Kapitel die schenkungsteuerliche und ertragsteuerliche internationale Doppelbesteuerung in Bezug auf die Länder Österreich und die Schweiz ausführlich erläutert. Im Mittelpunkt der Betrachtung stehen ausschließlich unentgeltliche bzw. teilentgeltliche Vermögensübertragungen im Rahmen der Schenkung unter Lebenden.
Die Logik der bisher erforschten und beschriebenen Management- und Führungstheorien müssen sich im Zeitalter der Digitalisierung weiterentwickeln. Die ursprüngliche Forschungsfrage nach einer wirksamen Implementierung von strategischen Entscheidungen passt nicht mehr zur Realität von disruptiven Veränderungen in der sogenannten VUCA Welt (Volatile, uncertain, complex, ambiguous).
Die Arbeit ist mutig und wertvoll, weil sie die Lücke zwischen neuen Entwicklungen in der Praxis und fehlenden umfassenden Theoriekonzepten in den Management-, Führungs- und Organisationswissenschaften offenlegt und zu schließen hilft.
Der erste Teil der Arbeit fasst die aktuellen Erkenntnisse rund um strategische Entscheidungsfindung in Unternehmen, globale Megatrends als Rahmenbedingung und Change-Management als Umsetzungshilfe zusammen. Die Schlussfolgerung aus dieser holistischen Betrachtung ist, dass die Forschungsfrage rückwärts gerichtet die Realität des 20. Jahrhunderts adressiert und für das Zeitalter der Digitalisierung keine hilfreiche Antwort bietet.
Vielmehr geht es um die weiter entwickelte Forschungsfrage, wie anpassungsfähige Organisationen entwickelt und gepflegt werden können. Solche Organisationen überleben disruptive Veränderungen nicht nur irgendwie, sondern sind so gestaltet, dass sie diese nutzen, um immer wieder neue Antworten auf sich entwickelnde Kundenbedürfnisse und in der internen Organisation zu finden.
Diese anpassungsfähige oder adaptive Organisation hat fünf wesentliche Dimensionen, die im zentralen Teil der Arbeit beleuchtet werden. Alle Themen entwickeln sich derzeit laufend weiter, so dass es noch keine letztgültige Antwort gibt welche Methoden sich durchsetzen werden.
Im Sinne eines holistischen Transformationsmanagements gibt das letzte Kapitel Hinweise auf die Herangehensweise, um die eigene Organisation in ihrer Anpassungsfähigkeit weiter zu entwickeln.
Die gründliche Diskussion einer Fülle von konzeptionellen Ansätzen in Verbindung mit einer bemerkenswerten Erfahrung der Autorin erlaubt es, die auftretende Problemstellung profunder anzugehen als bei einer rein akademischen Herangehensweise.
Increasing global competition forces organizations to improve their processes to gain a competitive advantage. In the manufacturing sector, this is facilitated through tremendous digital transformation. Fundamental components in such digitalized environments are process-aware information systems that record the execution of business processes, assist in process automation, and unlock the potential to analyze processes. However, most enterprise information systems focus on informational aspects, process automation, or data collection but do not tap into predictive or prescriptive analytics to foster data-driven decision-making. Therefore, this dissertation is set out to investigate the design of analytics-enabled information systems in five independent parts, which step-wise introduce analytics capabilities and assess potential opportunities for process improvement in real-world scenarios.
To set up and extend analytics-enabled information systems, an essential prerequisite is identifying success factors, which we identify in the context of process mining as a descriptive analytics technique. We combine an established process mining framework and a success model to provide a structured approach for assessing success factors and identifying challenges, motivations, and perceived business value of process mining from employees across organizations as well as process mining experts and consultants. We extend the existing success model and provide lessons for business value generation through process mining based on the derived findings. To assist the realization of process mining enabled business value, we design an artifact for context-aware process mining. The artifact combines standard process logs with additional context information to assist the automated identification of process realization paths associated with specific context events. Yet, realizing business value is a challenging task, as transforming processes based on informational insights is time-consuming.
To overcome this, we showcase the development of a predictive process monitoring system for disruption handling in a production environment. The system leverages state-of-the-art machine learning algorithms for disruption type classification and duration prediction. It combines the algorithms with additional organizational data sources and a simple assignment procedure to assist the disruption handling process. The design of such a system and analytics models is a challenging task, which we address by engineering a five-phase method for predictive end-to-end enterprise process network monitoring leveraging multi-headed deep neural networks. The method facilitates the integration of heterogeneous data sources through dedicated neural network input heads, which are concatenated for a prediction. An evaluation based on a real-world use-case highlights the superior performance of the resulting multi-headed network.
Even the improved model performance provides no perfect results, and thus decisions about assigning agents to solve disruptions have to be made under uncertainty. Mathematical models can assist here, but due to complex real-world conditions, the number of potential scenarios massively increases and limits the solution of assignment models. To overcome this and tap into the potential of prescriptive process monitoring systems, we set out a data-driven approximate dynamic stochastic programming approach, which incorporates multiple uncertainties for an assignment decision. The resulting model has significant performance improvement and ultimately highlights the particular importance of analytics-enabled information systems for organizational process improvement.
This dissertation investigates selected causes and effects of worker mobility between firms in three empirical studies for Germany. Chapter 2 investigates the productivity effects of worker inflows to manufacturing establishments, distinguishing inflows by their previous employers’ wage level, as a proxy for productivity. The chapter is motivated by several empirical studies which find that worker inflows from more productive or higher-paying firms increase hiring firms’ productivity. The analyses in chapter 2 are based on a unique linked employer-employee data set. The findings indicate that inflows from higher-paying establishments do not increase hiring establishments’ productivity, but inflows from lower-paying establishments do. Further analyses suggest that this effect is due to a positive selectivity of such inflows from their sending establishments. These findings can be interpreted as evidence of a reallocation process by which the best employees of lower-paying establishments become hired by higher-paying establishments. This process reflects the assortative pattern of worker mobility in Germany documented by Card et al. (2013) for the past decades. The chapter thus contributes to the literature by linking establishment-level productivity analysis to the assortative pattern of inter-firm worker mobility, thereby providing a micro-foundation for the latter.
Chapter 3 focuses on a positive selection of workers moving between firms from another, more specific perspective. The analysis focuses on the importance of regional labor market competition for establishments’ apprentice training and poaching of apprenticeship completers. Previous studies have found that firms provide less training if they are located in regions with strong labor market competition. This finding is usually interpreted as evidence of a higher risk of poaching in these regions. Yet, there is no direct evidence that regional competition is positively correlated with poaching. Building on a recently established approach to ex-post identify poaching of apprenticeship completers, this chapter is the first to directly investigate the correlation between regional labor market competition and poaching. Using German administrative data, it is found that competition indeed increases training establishments’ probability of becoming poaching victims. However, poaching victims do not change their apprenticeship training activity in reaction to poaching. Instead, the findings indicate that the lower training activity in competitive regions can be attributed to lower retention rates, as well as a less adverse selection and lower labor and hiring costs of apprenticeship completers hired from rivals.
Chapter 4 investigates the effects of local broadband internet availability on establishment-level employment growth. The analysis uses data for Germany in the years 2005-2009, when broadband was introduced in rural regions of Western Germany and in large parts of Eastern Germany. Technical frictions in broadband rollout are exploited to obtain exogenous variation in local broadband availability. The results suggest that broadband expansion had a positive effect on employment growth in the Western German service sector and a negative effect in Western German manufacturing, suggesting that broadband expansion has accelerated the reallocation of workers from manufacturing to services. Furthermore, this pattern of results is driven by pronounced positive effects in knowledge- and computer-intensive industries, suggesting that it is the actual use of broadband in the production process that leads to complementary hiring, respectively a slowdown of employment growth, in the respective sectors. For Eastern Germany, no significant employment growth effects are found.
