@inproceedings{matthies2019towards, abstract = {Software development comprises complex tasks which are performed by humans. It involves problem solving, domain understanding and communication skills as well as knowledge of a broad variety of technologies, architectures, and solution approaches. As such, software development projects include many situations where crucial decisions must be made. Making the appropriate organizational or technical choices for a given software team building a product can make the difference between project success or failure. Software development methods have introduced frameworks and sets of best practices for certain contexts, providing practitioners with established guidelines for these important choices. Current Agile methods employed in modern software development have highlighted the importance of the human factors in software development. These methods rely on short feedback loops and the self-organization of teams to enable collaborative decision making. While Agile methods stress the importance of empirical process control, i.e. relying on data to make decisions, they do not prescribe in detail how this goal should be achieved. In this paper, we describe the types and abstraction levels of data and decisions within modern software development teams and identify the benefits that usage of this data enables. We argue that the principles of data-driven decision making are highly applicable, yet underused, in modern Agile software development.}, author = {Matthies, Christoph and Hesse, Guenter}, booktitle = {International Conference on Software Technologies (ICSOFT)}, keywords = {software_engineering agile}, pages = {552-559}, title = {Towards Using Data to Inform Decisions in Agile Software Development: Views of Available Data}, year = 2019 }

@inproceedings{hesse2019application, abstract = {Industry 4.0 is becoming more and more important for manufacturers as the developments in the area of Internet of Things advance. Another technology gaining more attention is data stream processing systems. Although such streaming frameworks seem to be a natural fit for Industry 4.0 scenarios, their application in this context is still low. The contributions in this paper are threefold. Firstly, we present industry findings that we derived from site inspections with a focus on Industry 4.0. Moreover, our view on Industry 4.0 and important related aspects is elaborated. As a third contribution, we illustrate our opinion on why data stream processing technologies could act as an enabler for Industry 4.0 and point out possible obstacles on this way.}, author = {Hesse, Guenter and Sinzig, Werner and Matthies, Christoph and Uflacker, Matthias}, booktitle = {International Conference on Data Science, Technology and Applications (DATA)}, keywords = {industry4.0 data_stream_processing}, pages = {304-310}, title = {Application of Data Stream Processing Technologies in Industry 4.0 - What is Missing?}, year = 2019 }

@inproceedings{hesse2019quantitative, abstract = {With the demand to process ever-growing data volumes, a variety of new data stream processing frameworks have been developed. Moving an implementation from one such system to another, e.g., for performance reasons, requires adapting existing applications to new interfaces. Apache Beam addresses these high substitution costs by providing an abstraction layer that enables executing programs on any of the supported streaming frameworks. In this paper, we present a novel benchmark architecture for comparing the performance impact of using Apache Beam on three streaming frameworks: Apache Spark Streaming, Apache Flink, and Apache Apex. We find significant performance penalties when using Apache Beam for application development in the surveyed systems. Overall, usage of Apache Beam for the examined streaming applications caused a high variance of query execution times with a slowdown of up to a factor of 58 compared to queries developed without the abstraction layer. All developed benchmark artifacts are publicly available to ensure reproducible results.}, author = {Hesse, Guenter and Matthies, Christoph and Glass, Kelvin and Huegle, Johannes and Uflacker, Matthias}, booktitle = {IEEE International Conference on Distributed Computing Systems (ICDCS)}, keywords = {imported data_stream_processing}, pages = {1381-1392}, title = {Quantitative Impact Evaluation of an Abstraction Layer for Data Stream Processing Systems}, year = 2019 }

In this paper, we propose employing chatbots in the domain of software development with a focus on supporting analyses and measurements of teams' project data. The software project artifacts produced by agile teams during regular development activities, e.g. commits in a version control system, represent detailed information on how a team works and collaborates. Analyses of this data are especially relevant for agile retrospective meetings, where adaptations and improvements to the executed development process are discussed. Development teams can use these measurements to track the progress of identified improvement actions over development iterations. Chatbots provide a convenient user interface for interacting with the outcomes of retrospectives and the associated measurements in a chat-based channel that is already being employed by team members.}, author = {Matthies, Christoph and Dobrigkeit, Franziska and Hesse, Guenter}, booktitle = {IEEE/ACM International Workshop on Bots in Software Engineering (BotSE)}, keywords = {software_engineering}, note = {(accepted)}, pages = {34-37}, title = {An Additional Set of (Automated) Eyes: Chatbots for Agile Retrospectives}, year = 2019 }

There is an ongoing need to adapt university courses to changing requirements and shifts in industry. As an educator it is therefore vital to have access to methods, with which to ascertain the effects of curriculum design changes. In this paper, we present our approach of analyzing software repositories in order to gauge student behavior during project work. We evaluate this approach in a case study of a university undergraduate software development course teaching agile development methodologies. Surveys revealed positive attitudes towards the course and the change of employed development methodology from Scrum to Kanban. However, surveys were not usable to ascertain the degree to which students had adapted their workflows and whether they had done so in accordance with course goals. Therefore, we analyzed students' software repository data, which represents information that can be collected by educators to reveal insights into learning successes and detailed student behavior. We analyze the software repositories created during the last five courses, and evaluate differences in workflows between Kanban and Scrum usage.}, author = {Matthies, Christoph and Teusner, Ralf and Hesse, Guenter}, booktitle = {IEEE Frontiers in Education Conference (FIE)}, keywords = {development_artifacts software_engineering Kanban Scrum Education}, month = {oct}, pages = {1-9}, title = {Beyond Surveys: Analyzing Software Development Artifacts to Assess Teaching Efforts}, year = 2018 }

@inproceedings{Guenter2017a, abstract = {Against the backdrop of ever-growing data volumes and trends like the Internet of Things (IoT) or Industry 4.0, Data Stream Processing Systems (DSPSs) or data stream processing architectures in general receive a greater interest. Continuously analyzing streams of data allows immediate responses to environmental changes. A challenging task in that context is assessing and comparing data stream processing architectures in order to identify the most suitable one for certain settings. The present paper provides an overview about performance benchmarks that can be used for analyzing data stream processing applications. By describing shortcomings of these benchmarks, the need for a new application benchmark in this area, especially for a benchmark covering enterprise architectures, is highlighted. A key role in such an enterprise context is the combination of streaming data and business data, which is barely covered in current data stream processing benchmarks. Furthermore, first ideas towards the development of a solution, i.e., a new application benchmark that is able to fill the existing gap, are depicted.}, author = {Hesse, Guenter and Matthies, Christoph and Reissaus, Benjamin and Uflacker, Matthias}, booktitle = {ACM International Conference on Distributed and Event-based Systems (DEBS)}, keywords = {Internet_of_Things Performance_Benchmarking Stream_Processing Benchmark_Development Data_Stream_Processing}, pages = {359-362}, series = {DEBS '17}, title = {A New Application Benchmark for Data Stream Processing Architectures in an Enterprise Context: Doctoral Symposium}, year = 2017 }
