Daniel Beimborn develops a formal model in order to explore cooperative sourcing activities in the banking industry. Together with survey data from the German banking industry, the model is used in simulation studies which allow for compound analyses of causes and effects of cooperative sourcing.
The dynamics of the relationship between service recipient and service provider in IS outsourcing relationships recently gained increased attention as relationships are believed to have a considerable influence on IS outsourcing success. This study adds to this growing field of interest by developing an IS outsourcing relationship framework in the form of a process model. Three rather disjointed areas of research, namely contractual governance, relational norms, and control, have been set in a common context by interrelating them as the three main governance modes that jointly influence the relationship. One in-depth case study has been conducted in order to provide first empirical evidence and to gain deeper insights into the dynamics of relationship governance. The proposed model could be confirmed in general, revealing the following insights: first, contractual and relational governance modes determine the rules that govern the relationship while control is used to execute and enforce specified rules. All three jointly influence the state of the relationship. Second, relational norms have only been observed at an individual level and not at an organizational one. Third, formal control modes have been used to execute and enforce relational norms. This finding contradicts current control theory. Fourth, while contractual and relational governance are seen as complementary and equally important, relational norms have been left completely unmanaged in the observed organization due to a lack of adequate approaches. These results are discussed in detail to outline opportunities for further research.

This thesis is focusing on three little-explored contextual conditions that are important for a better understanding of digital platform ecosystems: digital platforms in a nascent stage of maturity, digital platforms built by incumbents, and digital platforms embedded in the IoT phenomenon. Thus, the thesis contributes to the question of how established companies navigating nascent digital platform ecosystems in the IoT. The work builds and contributes to the literature on digital platform ecosystems. Three main contributions are made through explorative qualitative research in the form of Delphi and case studies as well as through systematic literature research on the above-mentioned themes: First, the thesis synthesizes important knowledge about the nascent stage of digital platform ecosystems and identifies value co-creation challenges specific to this early maturity stage. Second, given the increasing importance of established companies in the platform discourse, this thesis identifies the intra- and inter-organizational challenges that incumbent organizations face in building digital platform ecosystems, emphasizing the importance of the organizational type in building a platform ecosystem. Third, the dissertation positions platforms in the IoT as a new digital platform instantiation within the scholarly platform discourse and outlines important phoneme-related characteristics that determine value creation.
Proven Patterns for Designing Evolvable High-Quality APIs--For Any Domain, Technology, or Platform APIs enable breakthrough innovation and digital transformation in organizations and ecosystems of all kinds. To create user-friendly, reliable and well-performing APIs, architects, designers, and developers need expert design guidance. This practical guide cuts through the complexity of API conversations and their message contents, introducing comprehensive guidelines and heuristics for designing APIs sustainably and specifying them clearly, for whatever technologies or platforms you use. In Patterns for API Design: Simplifying Integration with Loosely Coupled Message Exchanges, five expert architects and developers cover the entire API lifecycle, from launching projects and establishing goals through defining requirements, elaborating designs, planning evolution, and creating useful documentation. They crystallize the collective knowledge of many practitioners into 44 API design patterns, consistently explained with context, pros and cons, conceptual solutions, and concrete examples. To make their pattern language accessible, they present a domain model, a running case study, decision narratives with pattern selection options and criteria, and walkthroughs of real-world projects applying the patterns in two different industries. Identify and overcome API design challenges with patterns Size your endpoint types and operations adequately Design request and response messages and their representations Refine your message design for quality Plan to evolve your APIs Document and communicate your API contracts Combine patterns to solve real-world problems and make the right tradeoffs "This book provides a healthy mix of theory and practice, containing numerous nuggets of deep advice but never losing the big picture . . . grounded in real-world experience and documented with academic rigor applied and practitioner community feedback incorporated. I am confident that [it] will serve the community well, today and tomorrow." --Prof. Dr. Dr. h. c.
