| 2025 | Addressing Skills Shortages through Low-Code/No-Code: Skill Profiles and Implementation ChallengesabstractLow-code/no-code (LCNC) platforms promise low-barrier access to software development, increased efficiency, and programming with little to no code.This paper explores whether it is really possible to create software without writing code and with little programming knowledge.Using a systematic literature analysis, we lay a foundation for future research on the skills needed by citizen developers using LCNC tools in corporate and public-sector contexts.Our analysis of 58 articles identifies three key skill categories: hard skills, such as programming and working with APIs; soft skills, such as communication and collaboration; and domain-specific knowledge.However, challenges exist in the upskilling process.Additionally, generative AI (GenAI) shows potential to expand LCNC capabilities.Nevertheless, the intersection of LCNC and publicsector transformation remains underexplored, highlighting the need for deeper studies focused on sector-specific challenges, use cases, and long-term adoption.

| 2024 | Critical Success Factors for ERP Projects Revisited: An Update of Literature ReviewsabstractThe aim of our study was to provide an update to the research field of critical success factors (CSFs) of enterprise resource planning (ERP) system projects.Therefore, we conducted two literature reviews, more specifically systematic reviews of relevant articles in different databases and among several international conference proceedings from mid-2012 to 2023.These two reviews serve as an update of previous analyses that we conducted covering the period from 1998 until mid-2012.In our current analysis, we identified 272 relevant paperssingle or multiple case studies, surveys, and literature reviews or articles from which CSFs can be derived.From these existing studies, we discovered 33 different CSFs for ERP projects.The top three factors identified are 1) Top management support and involvement, 2) Organizational fit of the ERP system, and 3) User training.Our analysis shows that the majority of important CSFs are organizational factors with a strategic perspective.Nevertheless, important technological CSFs should also be decisively considered in ERP projects.These CSFs must be coordinated and aligned with the organizational factors in order to contribute to the holistic success of the ERP project.

| 2024 | Toward a Framework for Determining Methods of Evaluation in Design Science ResearchabstractEvaluation is a key phase of design science research, particularly in design-oriented information systems, one that involves analyzing and solving problems to create artifacts.Because the nature of those artifacts varies based on the problem, they necessitate different methods of evaluation, and selecting an appropriate one first requires identifying appropriate criteria for evaluation.This paper aims to pinpoint those criteria by systematically reviewing the literature, with particular focus on identifying various criteria for evaluation, their frequency, their significance in evaluating artifacts, and their connection to specific methods of evaluation.The findings suggest a framework for choosing the most suitable methods of evaluation based on the defined criteria that can enhance the rigor and relevance of the evaluation phase in design science research.

| 2023 | The Use of Digital Technologies in German Business ConsultanciesabstractThe increased digitalization of the economy and society has triggered drastic changes in companies and confronted them with enormous challenges.The consulting industry is also strongly affected by this digital transformation.In an exploratory study, we examined digitalization's impact on management consultancies in Germany and their use of digital technologies.In our article, we provide insights into which digital technologies are considered to be important for the different phases of consulting and how digitalization affects the work of management consultants.From the perspective of such consultants, we discuss the technologies currently in use and offer an outlook on their future importance based on an online survey.Our results reveal that many business consultancies already rely heavily on digitalization and use a variety of digital technologies in all phases of the consulting process.Although business consultancies currently use wellestablished technologies, they remain aware of the growing importance of modern technologies for the future of consulting services.

| 2023 | A Framework for Assessing the Sustainability of Intelligent Transport Systems in the Smart City ContextabstractIn their transition to smart cities, an increasing number of cities are pursuing strategies to improve efficiency of transport.One strategy is to achieve smart mobility, for which cities implement intelligent transport systems (ITS).Simultaneously, municipalities recognize their responsibility for creating a sustainable environment for citizens in the face of challenges like overpopulation, land shortage, and climate change.Interestingly, many ITS initiatives mainly focus on technical outcomes and overlook their impact on sustainability despite its key benefit for smart mobility.To fill this gap, we develop a framework for assessing the sustainability impact of ITS initiatives in this paper.We analyze the Sustainable Development Goals (SDGs) defined by the United Nations and relate them to various concepts of ITS to derive our framework.Thereby, our work bridges two fundamental perspectives for further research and supports decision-makers in choosing ITS initiatives that contribute to both smart mobility and sustainability.

| 2021 | The Impact of Digital Technologies on How Companies Work: Results from an Interview StudyabstractThe increasing digitalization of business and society has prompted drastic changes within enterprises and confronted them with enormous challenges.In our exploratory interview study, we examined the impact of digital technologies on how employees work in companies as well as the specific opportunities and challenges that small and medium-sized enterprises (SMEs) face as a result.On the whole, interviews revealed that digitalization has already triggered an array of changes in how employees work.Even so, the extent of each change and the perception of technological trends overall have varied among both employees and companies depending on their context.In response to those changes, the SMEs interviewed have applied a wide range of tools and strategies that have allowed them to exploit the opportunities offered by digital technologies and overcome the associated challenges.

| 2019 | ICT Usage in Industrial Symbiosis: Problem Identification and Study DesignabstractIndustrial symbiosis is a favored approach to balancing industry's economic growth and its environmental impact on a regional scale.Although the scientific literature reports a multitude of examples of industrial symbiosis around the world, this approach and its related concepts are not considered to be widespread in practice, due to various barriers.Information and management barriers are seen as significant obstacles to industrial symbiosis; however, they have not been adequately investigated yet.Empirical research capturing the perception of industrial actors is lacking.This applies especially to information and communication technology designed to reduce informational barriers.Therefore, in this research-inprogress paper, we will first examine these aspects by discussing related publications.In the second step, we develop a study design involving an online questionnaire to examine the extent of managerial and informational barriers that prevent industrial symbiosis as well as the perception of corresponding technological support.

| 2018 | Information System Backsourcing: A Systematic Literature AnalysisabstractAs information technology (IT) in private and public organizations continues to gain importance, information system outsourcing (ISO) has become a critical component of corporate strategy for many institutions. Consequently, a substantial amount of research has investigated topics around ISO decisions and outcomes. However, despite decades of ISO research, analyses that focus on information system (IS) backsourcing remain scarce. Therefore, in this paper, we share the results of a systematic literature analysis of papers that consider IS backsourcing. Within our paper, IS backsourcing is integrated into the wider research landscape of ISO. Finally, our study clearly identifies the need for further and more extensive research on IS backsourcing. The high dissatisfaction and failure of outsourcing arrangements should not be ignored. Both sourcing decisions and existing outsourcing arrangements must be analysed carefully and in the long term to ensure the success of the company. Christian Leyh, Thomas Schäffer, Trung Duc Nguyen |

| 2017 | Industry 4.0 and Lean Production - A Matching Relationship? An analysis of selected Industry 4.0 modelsabstractThe increasing digitalization of business and society has led to drastic changes within companies.Nearly all enterprises are facing enormous challenges dealing with topics such as Industry 4.0/Industrial Internet.With the goal of supporting companies to handle these challenges and "move" in an Industry 4.0 environment, several frameworks or reference models already exist.Here, we share the results of a detailed analysis of selected Industry 4.0 models.In particular, we foster in our analysis Lean Production aspects since the basic principles of Lean Management/Lean Production in existence since the 1980s have yielded appropriate measures to optimize production.These principles can and should be addressed and included by Industry 4.0 models as well.Our study provides a classification of 31 Industry 4.0 models/frameworks as well as the identification of needs for further research to enhance existing Industry 4.0 models more holistically.

| 2015 | Critical success factors for implementing supply chain management systems - the perspective of selected German enterprisesabstractThe aim of our study was to provide a contribution to the research field of critical success factors (CSFs) with a focus on SCM system implementations.Therefore, we conducted a systematic literature review in order to identify CSFs for those projects.On the basis of that review, we conducted interviews within German large-scale enterprises and with consultants experienced with SCM system implementations.As a result, we showed that all the factors found in the literature also affected the success of SCM projects in the studied companies.Additionally, we were able to identify six further CSFs with the interview study.However, within those SCM projects, technological factors gained more importance compared to those factors which influence the success of ERP projects the most.For SCM projects, factors like Data migration, as well as SCM system tests, are even more important than Top management support or Project management, which are the most important factors for ERP projects.

| 2014 | Critical Success Factors for ERP Projects in Small and Medium-sized Enterprises - The Perspective of Selected German SMEsabstractThe aim of our study was to provide a contribution to the research field of the critical success factors (CSFs) of ERP projects, with a specific focus on smaller enterprises (SMEs). Therefore, we conducted a systematic literature review in order to update the existing reviews of CSFs. On the basis of that review, we led several interviews within German SMEs that have implemented ERP systems. As a result, we showed that all factors found in the literature also affected the success of ERP projects in SMEs. However, within those projects, technological factors gained much more importance compared to those factors that most influence the success of larger ERP projects. For SMEs, factors such as the Organizational fit of the ERP system as well as ERP system tests are even more important than Top management support or Project management, which were the most important factors for large-scale companies.
