Chapter 6: HR machine learning in recruiting
In: Handbook of Research on Artificial Intelligence in Human Resource Management, Cheltenham, UK: Edward Elgar Publishing, 2022, S. 105–126, Cheltenham, UK

View Abstract
HR recruiting has been the focus of artificial intelligence (AI) based approaches for years. It is expected that applying AI - and especially machine learning - provides opportunities to improve HR processes, simplify, and automate finding, selecting, and evaluating candidates. This chapter reports a literature review to develop the HR recruiting machine learning model. It indicates whether expectations are met, reveals different person-environment fit dimensions focused, identifies challenges coming with these approaches, and discusses future research opportunities. It shows that most studies use decision trees or deep neural networks to predict person-job fit. Given the reported accuracy levels, the use of machine learning can increase the recruiting process's efficiency. Still, the focus is mainly on automatically predicting HR employees' or business managers' assessment of person-environment fit dimensions. The focus is not on fit in terms of an aptitude-diagnostic sense as a base for better decision making. Moreover, several approaches use discriminatory characteristics such as age, gender, or race in their machine learning models to predict an individual's appropriateness for a vacancy. Hence, various future research opportunities are discussed in terms of focusing on the different person-environment fit dimensions and not limiting the analysis to the person-job one. Besides, research should share datasets that enable the comparison of the different machine learning-based approaches, address fairness and transparency by focusing on approaches to eliminate discrimination in the models used, and focus on fit not only to increase efficiency but also to increase decision quality in an aptitude-diagnostic sense.

Recombining Layers of Digital Technology: How Users Create and Capture Value
In: Ahlemann F., Schütte R., Stieglitz S. (eds) International Conference on Wirtschaftsinformatik (WI 2021) : Innovation Through Information Systems. Lecture Notes in Information Systems and Organisation (48). Cham: Springer, pp. 259-274

View Abstract
Recombination is central to the creation of innovation. Since digital innovation is product and use agnostic, not only producers and firms can carry out recombination, but users themselves can select and recombine different digital resources. We investigate why users select and recombine digital resources from different layers (content, service, network, device) of the layered modular architecture in a personal context. Our results allow us to make three key contributions: (1) We underscore the importance to distinguish between intra-layer and inter-layer recombination and uncover different reasons to carry out intra- or inter-layer recombination. (2) We show that the network layer appears to be invisible to users when recombining digital resources in a personal context. (3) We outline recommendations and research questions for future research, based on our findings.

Innovation in Outsourcing : An Empirical Analysis of Outsourcing Vendors’ Innovation Approaches
In: Information Systems Outsourcing: The Era of Digital Transformation

View Abstract
Companies must drive innovation to stay competitive in today’s fast-changing and highly competitive environment. Therefore, they do also involve their outsourcing vendors as strategic partner for innovation. While recently at least some studies have examined innovation-oriented outsourcing partnerships and their outcomes, almost no research has yet focused on the innovation-related actions from an outsourcing vendor’s perspective. Our paper explores what kind of initiatives outsourcing vendors implement to create innovation for their customers. It analyzes a unique dataset of more than 830 innovation initiatives, as reported by global outsourcing vendor firms. The analysis identifies 22 different types of innovation initiatives, which are clustered into six different dimensions. Using these results plus nine interviews with outsourcing experts, we have developed a categorization model which allows for categorizing innovation-related vendor initiatives and provides a basis for evaluating the strategic importance of each category for firms searching for or evaluating an outsourcing vendor.

Social Image Research in the Age of Selfies
in 15th IFIP TC 13 International Conference, Bamberg, Germany, September 14-18, 2015, Proceedings, Part IV

View Abstract
Capturing and sharing images of ourselves and others has given rise to many applications and much human-computer interaction research. Social media has made it faster and easier than ever to share such photos, with "selfies", or photographs taken of oneself, invading popular culture. In this workshop, we will bring together researchers studying images of people in the context of HCI, whether thru mining such data, analyzing its use, or creating novel UIs for such.

Driving Process Innovation: The Application of a Role-Based Governance Model at Lufthansa Technik
In: vom Brocke, J.; Schmiedel, S. (eds.) (2015): BPM - Driving Innovation in a Digital World, Management for Professionals; Springer International Publishing Switzerland: p.275-286

View Abstract
Many stakeholders are involved in process operation and, consequently, also in process improvement and innovation. For the coordination of all stakeholders, an effective governance model with clearly defined roles and tasks can support process-oriented decision-making, which drives improvement and innovation. In this chapter, such a Business Process Management governance model is introduced. The role-based model FAR+ (Framework for Assignment of Responsibilities) provides precise assignment of process accountabilities and responsibilities. In the following, we apply FAR+ to an exemplary process at Lufthansa Technik. Based on this application, we derive implications for research and practice.

How Do Planned and Actual Interaction Structures Differ in Global Outsourcing Arrangements?
In: Kotlarsky, J., Oshri, I., and Willcocks, L. P. (eds.): The Dynamics of Global Sourcing: Perspectives and Practices, Springer Verlag, Berlin, 20-38.

View Abstract
How and why do actual interaction structures in global outsourcing arrangements differ from those originally planned? We use a social network perspective to analyze the structure of social interaction networks among operational staff and management of vendor and client firm in an outsourcing arrangement. We apply a case study approach to understand which interaction structures appear and whether they are in accordance with those structures formally defined in the outsourcing governance. We found that real interaction often differs from the plan and we provide theoretical explanations for understanding these deviations, thus contributing to the understanding of outsourcing governance and outsourcing relationship management.

The Role of SOA for BPO Intention - Proposing a Research Model
In: Raj Sharman, H. Raghav Rao, T. S. Raghu (Eds.): Exploring the Grand Challenges for Next Generation E-Business, Lecture Notes in Business Information Processing, Springer, Berlin, 122-136

View Abstract
How does the availability of an SOA within a firm affect the potential of and intention for outsourcing business activities? Since one of the promises of SOA is to modularize the IT representation of business processes, it should facilitate business process outsourcing in terms of buying the provision of single business functionalities. In this paper, we develop a conceptual research model that theorizes the relationship between SOA and BPO intention.

Proposing the Relationship between IT Business Alignment and the Business Value of Service-Oriented Architectures in Financial Firms
In: D. Kundisch, D. J. Veit, T. Weitzel, and C. Weinhardt (eds.): Enterprise Applications and Services in the Finance Industry, Lecture Notes in Business Information Processing, Springer, Berlin, 78-93

View Abstract
What is the business value of Service-Oriented Architectures (SOA) and how can we achieve it? This paper represents a conceptual piece of research which focuses on the impact of IT Business Alignment (ITBA) on the successful implementation of SOA, in terms of its business value. The contribution of this model is predominant in proposing a threefold effect of ITBA on achieving a successful implementation of SOA through the specific strategic needs defined by a particular firm in a specific industry, i.e., the banking industry. As a result, we show that the business strategy moderates the impact of SOA's general potentials on its actual business value and claim that this relationship is further moderated by ITBA, which must be thoroughly considered by practitioners deciding on introducing SOA in their firm.

Capability Map: Eine alternative Darstellungsweise für Unternehmensprozesse aus ressourcenorientierter Sicht
Beyer, J.; Mönch, L. (Hrsg.): Aspekte der Wirtschaftsinformatik: Methoden, Werkzeuge und Anwendungen, SCS-European Publishing House

View Abstract
Die vorliegende Arbeit befasst sich mit einem neuen Modellierungs- und Analysekonzept für Geschäftsprozesse, das aus zwei Unternehmenstheorien, der Resource-based Theory (RBT) und der Competence-based Theory (CBT), entwickelt wurde. Das Konzept versteht sich als eine zu den traditionellen, prozessbasierten Darstellungs- und Analysetechniken komplementäre Methode, die das Management bei der strategischen Entscheidungsfindung - z. B. über das Outsourcing bestimmter Teilprozesse - unterstützen soll. Das als "Capability Map" bezeichnete Konzept bietet einen neuartigen Ansatz zur strategischen Evaluierung der Komponenten von Geschäftsprozessen und erlaubt deren Darstellung als ein Netzwerk von sog. Capabilities. Unter dem Begriff "Capability" verstehen wir das Leistungsvermögen (materielle und immaterielle sowie intellektuelle Ressourcen) eines Unternehmens, eine gewisse Geschäftsfunktion auf beliebiger Granularitätsebene auszuführen. Die Anwendung der Capability Map auf die Prozesse einer deutschen Universalbank zeigen die Nutzenpotenziale dieses neuen Konzeptes auf.

View Abstract
Moderne netzwerkartige Unternehmensformen von Supply Webs über flexible Unternehmensallianzen bis hin zu letztlich völlig dezentralen und hochmodularen Dienstearchitekturen als Grundlage für Ad-hoc-Supply-Chains oder ein "Real Time Enterprise" erfordern eine gezielte Vernetzung zwischen einer Vielzahl von Akteuren zur systematischen Ausbeutung von Skaleneffekten. Dabei gibt es netzwerkspezifische Koordinationsprobleme, die aus der Existenz von Netzeffekten resultieren und besondere Anforderungen an eine schlagkräftige IT-Governance stellen. In diesem Beitrag wird gezeigt, dass die Philosophie des "Real Time Enterprise" technische und kulturelle Herausforderungen an die Unternehmensführung stellt. Eine ökonomische Analyse von Vernetzungsgleichgewichten am Beispiel Straight Through Processing im grenzüberschreitenden Wertpapierhandel verdeutlicht, welche Herausforderungen Vernetzungsprozesse mit sich bringen. Computersimulationen zeigen vielversprechende Resultate bezüglich der Lösbarkeit "klassischer" Netzwerkprobleme wie insbesondere des Start-up-Problems und unterstreichen den Wert moderner Strategien wie insbesondere der Coopetition.

View Abstract
In this paper, some of the main results of the research project "Economics of Standards in Information Networks" are presented and integrated into a single framework of technology diffusion. We present an agent-based simulation model that incorporates structural determinants of networks (centrality, topology/density) and individual decision making on the part of prospective technology users under realistic informational assumptions. Based upon these models, decision behavior in terms of the selection of standards and the diffusion of technological innovations in networks can be described; the model can serve as a tool for developing and evaluating various internalization strategies that aim at answering questions like how to consider the determinants of an increasingly global and networked market when choosing corporate strategies.

The Standardization Problem in Networks - A General Framework
Information Technology Standards and Standardization: A Global Perspective

View Abstract
Choosing the right set of communications standards is fundamental in any kind of interaction, espe-cially in the coordination of economic activities. This decision problem, generally referred to as "thestandardization problem", mainly results from interdependencies due to positive network effects. Theproblem has to be analyzed differently in centralized and decentralized networks. Therefore, we de-veloped separate models for each of these coordination forms which illustrate the advantages anddisadvantages of using standards. We based the economic parameters of the models and the discus-sion of its implications on empirical research. To gain information about the use of software standardsin enterprises, we conducted a comprehensive empirical survey, both in Germany and North America.It focuses on the corporate adoption and use of various IT standards, including Internet and electroniccommerce standards, business software and EDI. Approaching a general framework for analyzing thestandardization problem we combine three different research approaches: Formal analysis, a simula-tive approach and empirical studies (questionnaire, case studies).
