  abstract  = {These days design thinking is no longer a "new approach". Among practitioners, as well as academics, interest in the topic has gathered pace over the last two decades. However, opinions are divided over the longevity of the phenomenon: whether design thinking is merely "old wine in new bottles," a passing trend, or still evolving as it is being spread to an increasing number of organizations and industries. Despite its growing relevance and the diffusion of design thinking, knowledge on the actual status quo in organizations remains scarce. With a new study, the research team of Prof. Uebernickel and Stefanie Gerken investigates temporal developments and changes in design thinking practices in organizations over the past six years comparing the results of the 2015 "Parts without a whole" study with current practices and future developments. Companies of all sizes and from different parts of the world participated in the survey. The findings from qualitative interviews with experts, i.e., people who have years of knowledge with design thinking, were cross-checked with the results from an exploratory analysis of the survey data. This analysis uncovers significant variances and similarities in how design thinking is interpreted and applied in businesses.},

  abstract  = {Business model (BM) visualisations have become popular instruments with which to explain and manage today's complex business interactions. Using verbal and graphic elements, they provide simplified representations of reality and can support BM tasks that go beyond working memory's capacities. Visualisations thus reduce cognitive load and represent how practitioners and researchers think about BMs. However, they can also affect their thinking. This constitutes a thus far insufficiently explained tension between effectively reducing reality's complexity and the resulting cognitive biases. Building on cognitive load and framing theory, we qualitatively analysed 103 BM visualisations to explain how visual elements affect visualisations' cognitive effectiveness (helpfulness and ease of applicability) and unfold visual framing effects. By identifying five visual framing effects, we contribute to the cognitive BM perspective and explain how this set of cognitive factors affects BM management and research. We also found that most BM visualisations are not cognitively effective because they consist of unclear and non-parsimonious elements, limiting their cross-contextual application. Furthermore, the analysis revealed certain visualisations with strictly operationalised BM dimensions. These findings provide essential contributions to the literature on BM methods. We conclude by discussing how practitioners and researchers can use BM visualisations and their cognitive impacts accordingly.},

  abstract  = {Continuous verification of network security compliance is an accepted need. Especially, the analysis of stateful packet filters plays a central role for network security in practice. But the few existing tools which support the analysis of stateful packet filters are based on general applicable formal methods like Satifiability Modulo Theories (SMT) or theorem prover and show runtimes in the order of minutes to hours making them unsuitable for continuous compliance verification. In this work, we address these challenges and present the concept of state shell interweaving to transform a stateful firewall rule set into a stateless rule set. This allows us to reuse any fast domain specific engine from the field of data plane verification tools leveraging smart, very fast, and domain specialized data structures and algorithms including Header Space Analysis (HSA). First, we introduce the formal language FPL that enables a high-level human-understandable specification of the desired state of network security. Second, we demonstrate the instantiation of a compliance process using a verification framework that analyzes the configuration of complex networks and devices - including stateful firewalls - for compliance with FPL policies. Our evaluation results show the scalability of the presented approach for the well known Internet2 and Stanford benchmarks as well as for large firewall rule sets where it outscales state-of-the-art tools by a factor of over 41.},
