About

Dr. Enes Yigitbas studied computer science at the University of Paderborn and has been working as a researcher at the chair for Database and Information Systems since 2012. He completed his dissertation with the title “Model-Driven Engineering of Self-Adaptive User Interfaces” in 2019 with the grade “Summa cum laude”. Mr. Yigitbas' research focuses on model-driven and human-centered software engineering, self-adaptive software systems and human-computer interaction with a special focus on augmented and virtual reality. During his doctorate, his research work was linked to various industrial projects in the Software Innovation Campus Paderborn (SICP). In this context, he was significantly involved in the implementation and management of various projects such as "KoMoS" (Federal Ministry of Education and Research), "Digital in NRW" (Federal Ministry of Education and Research) or "AWARE" (Ministry of Economics, Innovation, Digitization and Energy of North Rhine-Westphalia -Westphalia). In addition to project and teaching activities, Mr. Yigitbas is also actively involved in various committee activities. He is the deputy spokesman of the german SIG for process models for operational application development and at the same time a member of various national and international committees (SIG adaptivity and user modeling, SIG management of application development and maintenance, and IFIP working group 13.2 - Methodology for User- Centered System Design). In addition, Mr. Yigitbas serves as a reviewer for various international conferences (MODELS, EICS, VL / HCC, SEAMS, ...) and journals (IJHCI, SoSym, UAIS, ...).

Von datenbasierter zu datengetriebener Geschäftsmodellentwicklung: Ein Überblick über Software-Tools und deren Datennutzung

S. Gottschalk, E. Yigitbas, Gesellschaft für Informatik, 2021

Die kontinuierliche Weiterentwicklung des eigenen Geschäftsmodells ist für eine Organisation von entscheidender Bedeutung, um wettbewerbsfähig und somit nachhaltig erfolgreich zu bleiben. Während für die Entwicklung neuer Geschäftsmodelle häufig Workshops und einfache Software-Tools zur Visualisierung genutzt werden, wurden in der Forschung bereits erste Ansätze von datengetriebener Geschäftsmodellentwicklung (GME) vorgestellt. Diese Ansätze nutzen dabei Daten, Informationen oder auch Wissen aus internen und externen Unternehmensquellen, um den GME-Prozess zu unterstützen. Innerhalb dieses Beitrags zeigen wir einige Ansätze aus der aktuellen Literatur und analysieren wie ihre Datennutzung den GME-Prozess unterstützt. Weiterhin stellen wir mit dem BMDL Feature Modeler ein Tool vor, welches den GME-Prozess mit Expertenwissen unterstützt.


Situation-specific Business Model Development Methods for Mobile App Developers

S. Gottschalk, E. Yigitbas, A. Nowosad, G. Engels, in: Enterprise, Business-Process and Information Systems Modeling, Springer, 2021

The development of effective business models is an essential task in highly competitive markets like mobile ecosystems. Existing development methods for these business models do not specifically focus that the development process profoundly depends on the situation (e.g., market size, regulations) of the mobile app developer. Here, a mismatch between method and situation can lead to poor resource management and longer development cycles. In software engineering, situational method engineering is used for software projects to configure a development method out of a method repository based on the project situation. Analogously, we support creating situation-specific business model development methods with a method base and new user roles. Here, the method engineer obtains the knowledge of the domain expert and stores it in the method base as elements, building blocks, and patterns. The expert knowledge is derived from a grey literature review on mobile development processes. After this, the method engineer constructs the development method based on the described situation of the business developer. We provide an open-source tool and evaluate it by constructing a local event platform's business model development method.

ProConAR: A Tool Support for Model-based AR Product Configuration

S. Gottschalk, E. Yigitbas, E. Schmidt, G. Engels, in: Human-Centered Software Engineering. HCSE 2020, Springer, 2020

Mobile shopping apps have been using Augmented Reality (AR) in the last years to place their products in the environment of the customer. While this is possible with atomic 3D objects, there is is still a lack in the runtime configuration of 3D object compositions based on user needs and environmental constraints. For this, we previously developed an approach for model-based AR-assisted product configuration based on the concept of Dynamic Software Product Lines. In this demonstration paper, we present the corresponding tool support ProConAR in the form of a Product Modeler and a Product Configurator. While the Product Modeler is an Angular web app that splits products (e.g. table) up into atomic parts (e.g. tabletop, table legs, funnier) and saves it within a configuration model, the Product Configurator is an Android client that uses the configuration model to place different product configurations within the environment of the customer. We show technical details of our ready to use tool-chain ProConAR by describing its implementation and usage as well as pointing out future research directions.

Model-based Product Configuration in Augmented Reality Applications

S. Gottschalk, E. Yigitbas, E. Schmidt, G. Engels, in: Human-Centered Software Engineering. HCSE 2020, Springer, 2020

Augmented Reality (AR) has recently found high attention in mobile shopping apps such as in domains like furniture or decoration. Here, the developers of the apps focus on the positioning of atomic 3D objects in the physical environment. With this focus, they neglect the configuration of multi-faceted 3D object composition according to the user needs and environmental constraints. To tackle these challenges, we present a model-based approach to support AR-assisted product con-figuration based on the concept of Dynamic Software Product Lines. Our approach splits products (e.g. table) into parts (e.g. tabletop, ta-ble legs, funnier) with their 3D objects and additional information (e.g. name, price). The possible products, which can be configured out of these parts, are stored in a feature model. At runtime, this feature model can be used to configure 3D object compositions out of the product parts and adapt to user needs and environmental constraints. The benefits of this approach are demonstrated by a case study of configuring modular kitchens with the help of a prototypical mobile-based implementation.

Model-based Hypothesis Engineering for Supporting Adaptation to Uncertain Customer Needs

S. Gottschalk, E. Yigitbas, G. Engels, in: Business Modeling and Software Design, Springer International Publishing, 2020, pp. 276-286

To build successful products, the developers have to adapt their product features and business models to uncertain customer needs. This adaptation is part of the research discipline of Hypotheses Engineering (HE) where customer needs can be seen as hypotheses that need to be tested iteratively by conducting experiments together with the customer. So far, modeling support and associated traceability of this iterative process are missing. Both, in turn, are important to document the adaptation to the customer needs and identify experiments that provide most evidence to the customer needs. To target this issue, we introduce a model-based HE approach with a twofold contribution: First, we develop a modeling language that models hypotheses and experiments as interrelated hierarchies together with a mapping between them. While the hypotheses are labeled with a score level of their current evidence, the experiments are labeled with a score level of maximum evidence that can be achieved during conduction. Second, we provide an iterative process to determine experiments that offer the most evidence improvement to the modeled hypotheses. We illustrate the usefulness of the approach with an example of testing the business model of a mobile application.
