Retrospective meetings are Scrum's instrument for process improvement and adaptation. They are considered one of the most important aspects of the Scrum method and its implementation in organizations. However, Retrospectives face their own challenges. Agile practitioners have highlighted common problems, i.e. headaches, that repeatedly appear in meetings and negatively impact the quality of process improvement efforts. To remedy these headaches, Retrospective activities, which can help teams think together and break the usual routine, have been proposed. In this research, we present case studies of educational and industry teams, investigating the effects of eleven Retrospective activities on five identified headaches. While we find evidence for the claimed benefits of activities in the majority of studied cases, application of remedies also led to new headaches arising.}, author = {Matthies, Christoph and Dobrigkeit, Franziska}, booktitle = {Proceedings of the 53rd Hawaii International Conference on System Sciences (HICSS)}, keywords = {imported}, note = {(to be published)}, title = {Towards Empirically Validated Remedies for Scrum Retrospective Headaches}, year = 2020 }

  @inproceedings{Matthies2019ICSE_SRC, abstract = {Working in iterations and repeatedly improving team workflows based on collected feedback is fundamental to agile software development processes. Scrum, the most popular agile method, provides dedicated retrospective meetings to reflect on the last development iteration and to decide on process improvement actions. However, agile methods do not prescribe how these improvement actions should be identified, managed or tracked in detail. The approaches to detect and remove problems in software development processes are therefore often based on intuition and prior experiences and perceptions of team members. Previous research in this area has focused on approaches to elicit a team's improvement opportunities as well as measurements regarding the work performed in an iteration, e.g. Scrum burn-down charts. Little research deals with the quality and nature of identified problems or how progress towards removing issues is measured. In this research, we investigate how agile development teams in the professional software industry organize their feedback and process improvement approaches. In particular, we focus on the structure and content of improvement and reflection meetings, i.e. retrospectives, and their outcomes.

This data is the foundation for a broad spectrum of services driven and improved by trajectory data mining. However, for hybrid transactional and analytical workloads, the storing and processing of rapidly accumulated trajectory data is a non-trivial task. In this paper, we propose an approach to optimize the trajectory data management capabilities for relational database systems. Based on the observations that the relational database structure is well-suited to store trajectory data in the sample point format and that the access patterns for trajectory data change over time, we develope a concept for optimized spatio-temporal data structures for in-memory column stores and describe a workload-aware tiered data compression approach. The first evaluations of the approach demonstrate that the observed data access patterns of different real-world use cases are supporting the proposed system architecture.}, author = {Richly, Keven}, journal = {Proceedings of the VLDB 2019 PhD Workshop, co-located with the 45th International Conference on Very Large Databases (VLDB 2019)}, keywords = {imported}, title = {Optimized Spatio-Temporal Data Structures for Hybrid Transactional and Analytical Workloads on Columnar In-Memory Databases}, year = 2019 }

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.

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 = {Proceedings of the 14th International Conference on Software Technologies - Volume 1: ICSOFT}, keywords = {agile software_engineering}, organization = {INSTICC}, pages = {552-559}, publisher = {SciTePress}, title = {Towards Using Data to Inform Decisions in Agile Software Development: Views of Available Data}, year = 2019 }

To further increase both performance and efficiency, data that is not relevant for the query result should be skipped as early as possible. One way to achieve this goal is horizontal partitioning to improve static partition pruning. As part of our ongoing work on workload-driven partitioning, we have implemented a recent approach called aggressive data skipping and extended it to handle both analytical as well as transactional access patterns. In this paper, we evaluate this approach with the workload and data of a production enterprise system of a Global 2000 company.

  @article{perscheid2018ebola, abstract = {Background: Since the beginning of the Ebola outbreak in West Africa in 2014, more than 11,000 people died. For outbreaks of infectious diseases like this, the rapid implementation of control measures is a crucial factor for containment. In West African countries, outbreak surveillance is a paper-based process with significant delays in forwarding outbreak information, which affects the ability to react adequately to situational changes. Our objective therefore was to develop a tool that improves data collection, situation assessment, and coordination of response measures in outbreak surveillance processes for a better containment. Methods: We have developed the Surveillance and Outbreak Response Management System (SORMAS) based on findings from Nigeria's 2014 Ebola outbreak. We conducted a thorough requirements engineering and defined personas and processes. We also defined a data schema with specific variables to measure in outbreak situations. We designed our system to be a cloud application that consists of interfaces for both mobile devices and desktop computers to support all stakeholders in the process. In the field, health workers collect data on the outbreak situation via mobile applications and directly transmit it to control centers. At the control centers, health workers access SORMAS via desktop computers, receive instant updates on critical situations, react immediately on emergencies, and coordinate the implementation of control measures with SORMAS. Results: We have tested SORMAS in multiple workshops and a field study in July 2015. Results from workshops confirmed derived requirements and implemented features, but also led to further iterations on the systems regarding usability. Results from the field study are currently under assessment. General feedback showed high enthusiasm about the system and stressed its benefits for an effective outbreak containment of infectious diseases. Conclusions: SORMAS is a software tool to support health workers in efficiently handling outbreak situations of infectious diseases, such as Ebola. Our tool enables a bi-directional exchange of situational data between individual stakeholders in outbreak containment. This allows instant and seamless collection of data from the field and its instantaneous analysis in operational centers. By that, SORMAS accelerates the implementation of control measures, which is crucial for a successful outbreak containment.}, author = {Perscheid, Cindy and Benzler, Justus and Hermann, Claus and Janke, Michael and Moyer, David and Laedtke, Todd and Adeoye, Olawunmi and Denecke, Kerstin and Kirchner, Göran and Beerman, Sandra and Schwarz, Norbert and Tom-Aba, Daniel and Krause, Gérard}, journal = {Frontiers in ICT}, keywords = {Ebola_surveillance_process cp epidemiology healthcare infectious_diseases mobile_applications requirements_engineering}, month = {April}, pages = 7, title = {Ebola Outbreak Containment: Real-Time Task and Resource Coordination With SORMAS}, volume = 5, year = 2018 }

These methods rely on subjective evaluations and their results are hard to quantify. After changes are implemented it is difficult to assess their impact and whether an identified issue was fully resolved. In order to tackle these challenges we propose an approach relying on analysing data created by software development teams. Software developers create more than just code during regular development activities.

  @inproceedings{schlosser2018dynamic, abstract = {Most online markets are characterized by competitive settings and limited demand information. Due to the complexity of such markets, efficient pricing strategies are hard to derive. We analyze stochastic dynamic pricing models in competitive markets with multiple offer dimensions, such as price, quality, and rating. In a first step, we use a simulated test market to study how sales probabilities are affected by specific customer behaviors and the strategic interaction of price reaction strategies. Further, we show how different state-of-the-art learning techniques can be used to estimate sales probabilities from partially observable market data. In a second step, we use a dynamic programming model to compute an effective pricing strategy which circumvents the curse of dimensionality. We demonstrate that the strategy is applicable even if the number of competitors is large and their strategies are unknown. We show that our heuristic can be tuned to smoothly balance profitability and speed of sales. Further, our approach is currently applied by a large seller on Amazon for the sale of used books.

In 2015 and 2017, we conducted two introductory MOOCs on object-oriented programming in Java with each over 10,000 registered participants. In this paper, we analyze course scores, quiz results and self-stated skill levels of our participants. The aim of our analysis is to uncover factors influencing the retention of acquired knowledge, such as time passed or knowledge application, in order to improve long-term success. While we know that some participants learned the programming basics within our course, we lack information on whether this knowledge was applied and fortified after the course's end. To fill this knowledge gap, we conducted a survey in 2018 among all participants of our 2015 and 2017 programming MOOCs. The first part of the survey elicits responses on whether and how MOOC knowledge was applied and gives participants opportunity to voice individual feedback. The second part of the survey contains several questions of increasing difficulty and complexity regarding course content in order to learn about the consolidation of the acquired knowledge. We distinguish three programming knowledge areas in the survey: First, understanding of concepts, such as loops and boolean algebra. Second, syntax knowledge, such as specific keywords. Third, practical skills including debugging and coding. We further analyzed the long-term effects separately per participant skill group. While answer rates were low, the collected data shows a decrease of knowledge over time, relatively unaffected by skill level. Application of the acquired knowledge improves the memory retention rates of MOOC participants across all skill levels.}, author = {Teusner, Ralf and Matthies, Christoph and Staubitz, Thomas}, booktitle = {2018 IEEE Frontiers in Education Conference (FIE)}, keywords = {myown}, title = {What Stays in Mind? - Retention Rates in Programming MOOCs}, year = 2018 }

For success- ful pricing strategies, frequent price adjustments as well as anticipation of market dynamics are crucial. Both effects are challenging as competitive markets are complex and computations of optimized pricing adjustments can be time-consuming. We analyze stochastic dynamic pricing models under oligopoly competition for the sale of perishable goods. To circumvent the curse of dimensionality, we propose a heuristic approach to efficiently compute price adjustments. To demonstrate our strategy’s applicability even if the number of competitors is large and their strategies are unknown, we consider different competitive settings in which competitors frequently and strategically adjust their prices. For all settings, we verify that our heuristic strategy yields promising results. We compare the performance of our heuristic against upper bounds, which are obtained by optimal strategies that take advantage of perfect price an- ticipations. We find that price adjustment frequencies can have a larger impact on expected profits than price anticipations. Finally, our approach has been applied on Amazon for the sale of used books. We have used a seller’s historical market data to calibrate our model.

  @inproceedings{matthies2018seem, abstract = {Using university capstone courses to teach agile software development methodologies has become commonplace, as agile methods have gained support in professional software development. This usually means students are introduced to and work with the currently most popular agile methodology: Scrum. However, as the agile methods employed in the industry change and are adapted to different contexts, university courses must follow suit. A prime example of this is the Kanban method, which has recently gathered attention in the industry. In this paper, we describe a capstone course design, which adds the hands-on learning of the lean principles advocated by Kanban into a capstone project run with Scrum. This both ensures that students are aware of recent process frameworks and ideas as well as gain a more thorough overview of how agile methods can be employed in practice. We describe the details of the course and analyze the participating students' perceptions as well as our observations. We analyze the development artifacts, created by students during the course in respect to the two different development methodologies. We further present a summary of the lessons learned as well as recommendations for future similar courses.

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.

We analyze the {DTRS}11 corpus, comprising 16 sessions of design conversation that contain 9830 sentences, with automated Latent Semantic Analysis ({LSA}) to identify potential low coherent turns. We argue that an additional manual coherence analysis with the Topic Markup Scheme ({TMS}) further qualifies preselected turns. This mixed method procedure constitutes a promising pragmatic instrument for locating low coherent turns in large corpora. 297 distinct low coherent turns out of a total amount of 6072 turns were successfully retained. The selected data contains twice as much turns that shift the focus of attention within an existing design issue as turns that interrupt and introduce a new design issue. Based on an interpretative analysis of low coherent turns, we suggest distinguishing between turns that interrupt the focus of attention and turns that shift the focus of attention through either diversifying, reframing, or selective tendencies.}, author = {Menning, Axel and Grasnick, Bastien Marvin and Ewald, Benedikt and Dobrigkeit, Franziska and Nicolai}, booktitle = {Analysing Design Thinking: Studies of Cross-Cultural Co-Creation}, edition = 1, editor = {Christensen, Bo T. and Ball, Linden J. and Halskov, Kim}, keywords = {imported}, pages = {291--309}, publisher = {{CRC} Press}, title = {Combining Computational and Human Analysis to Study Low Coherence in Design Conversations}, year = 2017 }

Furthermore, the tests for the functionality that is to be developed are oftentimes already available in MOOCs and simply need to be executed, leading to less involvement with developing appropriate tests. In order to tackle these issues while maintaining a high degree of automation and scalability, we developed Prof. CI, a novel approach to conducting online exercises. Prof. CI leverages the existing automation infrastructure that developers use daily, i.e. CI services and Github workflows, to teach test-driven development (TDD) practices.

MOOCs that are teaching programming skills aim to incorporate practical exercises into the course corpus to give students the hands-on experience necessary for understanding and mastering programming. These exercises, apart from technical challenges, come with a series of questions to be addressed, for example: which fraction of the participants' time should they take (compared to video lectures and other course activities), which difficulty should be aimed for, how much guidance should be offered and how much repetition should be incorporated? The perceived difficulty of a task depends on previous knowledge, supplied hints, the required time for solving and the number of failed attempts the participant made. Furthermore, the detail and accuracy of the problem description, the restrictiveness of the applied test cases and the preparation provided specifically for a given exercise also influence the perceived difficulty of a task. In this paper, we explore the data of three programming courses to find criteria for optimal practical programming exercises. Based on over 3 million executions and scoring runs of participants' task submissions, we aim to deduct exercise difficulty, student patterns in approaching the tasks and potential flaws in task descriptions and preparatory videos. We compare our findings to in class trainings and traditional, mostly video and quiz based MOOCs.

The main challenge in doing so is to assess whether students apply the methods correctly without requiring complete supervision throughout the entire project. This paper presents experiences from a classroom project where 38 students developed a single system using a scaled version of Scrum. Surveys helped us to identify which elements of Scrum correlated most with student satisfaction or posed the biggest challenges. These insights were augmented by a team of tutors, which accompanied main meetings throughout the project to provide feedback to the teams, and captured impressions of method application in practice. Finally, we performed a post-hoc, tool-supported analysis of collaboration artifacts to detect concrete indicators for anti-patterns in Scrum adoption. Through the combination of these techniques we were able to understand how students implemented Scrum in this course and which elements require further lecturing and tutoring in future iterations. Automated analysis of collaboration artifacts proved to be a promising addition to the development process that could potentially reduce manual efforts in future courses and allow for more concrete and targeted feedback, as well as more objective assessment.}, address = {New York, NY, USA}, author = {Matthies, Christoph and Kowark, Thomas and Richly, Keven and Uflacker, Matthias and Plattner, Hasso}, booktitle = {Proceedings of the 38th International Conference on Software Engineering Companion}, keywords = {Scrum classroom_project collaboration_analysis imported software_engineering}, month = 5, pages = {313-322}, publisher = {ACM}, series = {ICSE '16}, title = {How Surveys, Tutors, and Software Help to Assess Scrum Adoption in a Classroom Software Engineering Project}, year = 2016 }

This restricts the areas that students can gather firsthand experiences in. In this paper we describe a university software engineering course which applies the values of the Agile Manifesto to the course design itself. Students work in self-organizing teams and are given significant authority and responsibility for their work, including planning, scheduling, and workload assignment. During the project they are guided by tutors and supported by a minimal amount of traditional lectures. We regularly assess learning progress and satisfaction via surveys and compare the results to those of more controlled course setups. We have observed positive student attitudes towards the self-organizing approach, with no adverse effects of the novel course design in terms of participant satisfaction or learning success.

This approach poses the problem of grading and evaluating practical project work as well as process conformance during development. Yet, few best practices exist for measuring the success of students in implementing agile practices. Most university courses rely on observations during the course or final oral exams. In this paper, we propose a set of metrics which give insights into the adherence to agile practices in teams. The metrics identify instances in development data, e.g. commits or user stories, where agile processes were not followed. The identified violations can serve as starting points for further investigation and team discussions. With contextual knowledge of the violation, the executed process or the metric itself can be refined. The metrics reflect our experiences with running a software engineering course over the last five years. They measure aspects which students frequently have issues with and that diminish process adoption and student engagement. We present the proposed metrics, which were tested in the latest course installment, alongside tutoring, lectures, and oral exams.}, author = {Matthies, Christoph and Kowark, Thomas and Uflacker, Matthias and Plattner, Hasso}, booktitle = {2016 IEEE Frontiers in Education Conference (FIE)}, keywords = {agile imported metrics software_engineering}, month = {October}, pages = {1-5}, publisher = {IEEE}, title = {Agile Metrics for a University Software Engineering Course}, year = 2016 }

Additionally, monolingual data was also collected for all four languages. Sentences in the parallel corpus were automatically aligned and a manual analysis of 200 documents by native experts found that a minimum of 79% of sentences were correctly aligned in all language pairs. We demonstrate the utility of the corpus by running baseline machine translation experiments. We show that for all language pairs, a statistical machine translation system trained on the parallel corpora achieves performance that rivals or exceeds the state of the art in the biomedical domain.

The knowledge about highly frequented regions as well as peak times in specific areas provides a crucial business advantage to competitors. Today, business relevant decisions about the positioning of service providers and advertising spaces or the balancing of capacity are primarily based on experience only. In this paper, we present a novel approach to gain knowledge about the distribution of potential customers over time and space based on the data of taxi rides, which have been recorded for documentation purposes. By leveraging the performance of in-memory databases, we build an applica- tion, which allows the user to analyze about 700 million taxi rides in real-time. The application allows companies to get an impression in which areas and in what timeframes they can reach a large audience of potential customers. Additionally, we demonstrate that the developed visualization concept enables the comparison of different regions and allows to analyze trends in the customer flow over time.}, author = {Richly, Keven and Teusner, Ralf}, booktitle = {The 2nd EAI International Conference on IoT in Urban Space (Urb-IoT)}, keywords = {imported}, title = {Where is the Money Made?

A growing number of users and an increasing demand for enterprise applications can saturate or even overload single- node database systems at peak times. Better performance can be achieved by improving a single machine’s hardware but it is often cheaper and more practicable to follow a scale-out approach and replicate data by using additional machines. In this paper we present Hyrise-R, a lazy master replication system for the in-memory database Hyrise. By setting up a snapshot-based Hyrise cluster, we increase both performance by distributing queries over multiple instances and availability by utilizing the redundancy of the cluster structure. This paper describes the architecture of Hyrise- R and details of the implemented replication mechanisms.

Additionally, we discuss the added technical features such as user groups along with the expected and actual outcomes. We relate our experiences from the second and third iteration to those of the first one. Findings show that demand for high quality content endures, even if the topic is rather specialized. Expectations of participants towards online courses are growing in general due to an increasing amount of organizations offering lectures. MOOCs are compared to school lessons, distance education and seminars. As a result, the pressure on platforms is increasing with regards to content, service and reliability. To cope with that, we share best practices and propose promising improvements to the platform and future courses.}, author = {Teusner, Ralf and Richly, Keven and Staubitz, Thomas and Renz, Jan}, booktitle = {EMOOCs 2015: Third European MOOCs Stakeholder Summit}, journal = {EMOOCs 2015: European MOOCs Stakeholder Summit}, keywords = {Iterations_MOOCs}, month = 5, number = 1, pages = {147-156}, title = {Enhancing Content between Iterations of a MOOC – Effects on Key Metrics}, volume = 1, year = 2015 }

  @conference{Lars2015a, abstract = {Value driver trees are a well-known methodology to model dependencies such as the definition of key performance indicators. While the models have well-known semantics, they lack the right tool support for business simulations, because a flexible implementation that supports multidimensional, hierarchical value driver trees and data bindings is very complex and computationally challenging. This paper tackles this problem by proposing an approach for generic enterprise simulations which are based on value driver trees. Our approach is two-fold: we present the definition of a simulation meta model at design time, and the run-time simulation tool. The simulation meta model describes the structure of the dependency graph, the data binding, and the parametrization of the model to simulate data changes. The simulation tool can then be used to create and edit simulation model instances and run simulations in real-time by leveraging an in-memory column store. Besides the formal description of the approach, this work presents a prototypical implementation of the simulation tool and an evaluation using data of a consumer packaged goods company.}, author = {Butzmann, Lars and Klauck, Stefan and Mueller, Stephan and Uflacker, Matthias and Plattner, Hasso and Sinzig, Werner}, booktitle = {Datenbanksysteme für Business, Technologie und Web (BTW), 16.

This platform permits high performance OLAP with massive scale-out capabilities, while concurrently allowing OLTP workloads. This dual capability enables analytics over real-time changing data and allows fine grained user-specified service level agreements (SLAs) on data freshness. We advocate the decoupling of core database components such as query processing, concurrency control, and persistence, a design choice made possible by advances in high-throughput low-latency networks and storage devices. We provide full ACID guarantees and build on a logical timestamp mechanism to provide MVCC-based snapshot isolation, while not requiring synchronous updates of replicas. Instead, we use asynchronous update propagation guaranteeing consistency with timestamp validation. We provide a view into the design and development of a large scale data management platform for real-time analytics, driven by the needs of modern enterprise customers.}, author = {Goel, Anil and Pound, Jeffrey and Auch, Nathan and Bumbulis, Peter and MacLean, Scott and Färber, Franz and Gropengiesser, Francis and Mathis, Christian and Bodner, Thomas and Lehner, Wolfgang}, journal = {Proceedings of the VLDB Endowment}, keywords = {distributed_database htap}, number = 12, pages = {1716--1727}, title = {Towards Scalable Real-time Analytics: An Architecture for Scale-out of OLXP Workloads}, volume = 8, year = 2015 }
