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.

From a declarative specification of a\r\nconsistency relation, several operations including forward and\r\nbackward transformations, (concurrent) synchronisation, and\r\nconsistency checks can be automatically derived. For TGGs to be\r\napplicable in realistic application scenarios, expressiveness in\r\nterms of supported language features is very important. A TGG tool\r\nis schema compliant if it can take domain constraints, such as\r\nmultiplicity constraints in a meta-model, into account when\r\nperforming consistency management tasks. To guarantee schema\r\ncompliance, most TGG tools allow application conditions to be\r\nattached as necessary to relevant rules. This strategy is\r\nproblematic for at least two reasons: First, ensuring compliance to\r\na sufficiently expressive schema for all previously mentioned\r\nderived operations is still an open challenge; to the best of our\r\nknowledge, all existing TGG tools only support a very restricted\r\nsubset of application conditions. Second, it is conceptually\r\ndemanding for the user to indirectly specify domain constraints as\r\napplication conditions, especially because this has to be completely\r\nrevisited every time the TGG or domain constraint is changed. While\r\ndomain constraints can in theory be automatically transformed to\r\nobtain the required set of application conditions, this has only\r\nbeen successfully transferred to TGGs for a very limited subset of\r\ndomain constraints. To address these limitations, this paper\r\nproposes a search-based strategy for achieving schema compliance. We\r\nshow that all correctness and completeness properties, previously\r\nproven in a setting without domain constraints, still hold when\r\nschema compliance is to be additionally guaranteed. An\r\nimplementation and experimental evaluation are provided to support\r\nour claim of practical applicability.</jats:p>","lang":"eng"}],"status":"public","type":"journal_article","publication":"Formal Aspects of Computing","language":[{"iso":"eng"}],"_id":"23525","user_id":"53103","department":[{"_id":"28"},{"_id":"66"}]},{"_id":"20540","department":[{"_id":"66"},{"_id":"534"}],"user_id":"8447","language":[{"iso":"eng"}],"publication":"Proceedings of the 9th International Conference on Model-Driven Engineering and Software Development ","type":"conference","status":"public","date_updated":"2022-01-06T06:54:29Z","publisher":"SCITEPRESS","date_created":"2020-11-27T16:14:05Z","author":[{"last_name":"Jovanovikj","orcid":"https://orcid.org/0000-0002-1838-794X","full_name":"Jovanovikj, Ivan","id":"39187","first_name":"Ivan"},{"full_name":"Thottam, Anu Tony","last_name":"Thottam","first_name":"Anu Tony"},{"full_name":"Joseph Vincent, Vishal","last_name":"Joseph Vincent","first_name":"Vishal"},{"first_name":"Enes","orcid":"0000-0002-5967-833X","last_name":"Yigitbas","id":"8447","full_name":"Yigitbas, Enes"},{"full_name":"Sauer, Stefan","id":"447","last_name":"Sauer","first_name":"Stefan"},{"first_name":"Gregor","last_name":"Engels","id":"107","full_name":"Engels, Gregor"}],"title":"A Modeling Workbench for the Development of Situation-specific Test Co-Migration Methods ","conference":{"location":"Vienna","name":"International Conference on Model-Driven Engineering and Software Development "},"year":"2021","page":"232-239","citation":{"chicago":"Jovanovikj, Ivan, Anu Tony Thottam, Vishal Joseph Vincent, Enes Yigitbas, Stefan Sauer, and Gregor Engels. “A Modeling Workbench for the Development of Situation-Specific Test Co-Migration Methods .” In <i>Proceedings of the 9th International Conference on Model-Driven Engineering and Software Development </i>, 232–39.

Despite the success of prominent examples, such as Uber and Airbnb, creating a profitable platform ecosystem presents a key challenge for many companies across all industries. Although research provides knowledge about platforms’ different value drivers (e.g., network effects), companies that seek to transform their current business model into a platform-based one lack an artifact to reduce knowledge boundaries, collaborate effectively, and cope with the complexities and dynamics of platform ecosystems. We address this challenge by developing two artifacts and combining research from variability modeling, business model dependencies, and system dynamics. This paper presents a design science research approach to develop the platform ecosystem modeling language and the platform ecosystem development tool that support researcher and practitioner by visualizing and simulating platform ecosystems.

Here, domain experts can guide the choices of tasks and decisions with their knowledge. Nevertheless, this knowledge needs to match the situation of the company (e.g., financial resources) and the application domain of the product/service (e.g., mobile app) to reduce the risk of developing ineffective business models with low market penetration. This is not covered by one-size-fits-all development methods without tailoring before the enaction.\r\nTherefore, we conduct a design science study to create a situation-specific development approach for business models. Based on situational method engineering and our previous work in storing knowledge of methods and models in distinct repositories, this paper shows the situation-specific composition and enaction of business model development methods. First, the method engineer composes the development method out of both repositories based on the situational context. Second, the business developer enacts the method and develops the business model.  We implement the approach in a tool and evaluate it with a industrial case study on mobile apps."}],"status":"public","project":[{"_id":"1","name":"SFB 901"},{"_id":"4","name":"SFB 901 - Project Area C"},{"name":"SFB 901 - Subproject C5","_id":"17"}],"_id":"25528","user_id":"47208","department":[{"_id":"66"}],"keyword":["Business Model Development","Situational Method Engineering","Lean Development","Kanban Boards","Canvas Models"],"language":[{"iso":"eng"}],"year":"2021","citation":{"bibtex":"@inbook{Gottschalk_Yigitbas_Nowosad_Engels_2021, title={Situation- and  Domain-specific Composition and Enactment of Business Model Development Methods}, booktitle={Product-focused Software Process Improvement}, publisher={Springer}, author={Gottschalk, Sebastian and Yigitbas, Enes and Nowosad, Alexander and Engels, Gregor}, year={2021} }","short":"S.

Since uncertainties about future developments increase planning difficulty, flexibility potentials such as synergies between the electricity, gas, heat, and transport sector often remain unused. In this paper, we therefore present a novel module-based concept for a decision support system that helps distribution network planners to identify cross-sectoral synergies and to select optimal network assets such as transformers, cables, pipes, energy storage systems or energy conversion technology. The concept enables long-term transformation plans and supports distribution network planners in designing reliable, sustainable and cost-efficient distribution networks for future demands.","lang":"eng"}],"editor":[{"last_name":"Breitner","full_name":"Breitner, Michael H.","first_name":"Michael H."},{"full_name":"Lehnhoff, Sebastian","last_name":"Lehnhoff","first_name":"Sebastian"},{"first_name":"Astrid","full_name":"Nieße, Astrid","last_name":"Nieße"},{"full_name":"Staudt, Philipp","last_name":"Staudt","first_name":"Philipp"},{"last_name":"Weinhardt","full_name":"Weinhardt, Christof","first_name":"Christof"},{"first_name":"Oliver","last_name":"Werth","full_name":"Werth, Oliver"}],"date_created":"2021-01-28T10:05:44Z","author":[{"last_name":"Kirchhoff","full_name":"Kirchhoff, Jonas","id":"39928","first_name":"Jonas"},{"full_name":"Burmeister, Sascha Christian","id":"32685","last_name":"Burmeister","first_name":"Sascha Christian"},{"last_name":"Weskamp","full_name":"Weskamp, Christoph","first_name":"Christoph"},{"first_name":"Gregor","last_name":"Engels","id":"107","full_name":"Engels, Gregor"}],"oa":"1","date_updated":"2022-04-30T13:48:49Z","conference":{"name":"Pre-Conference 16.

Unternehmen agieren hierbei als Anbieter von Software-Plattformen, auf denen Drittanbieter Softwarelösungen für den Markt anbieten können.  Etablierte Beispiele sind hierbei sogenannte App-Stores, die z.B. von Google oder Apple angeboten werden.\r\n\r\nBeim Aufbau von Software-Ökosystemen müssen vom Plattformanbieter viele architektonische Entwurfsentscheidungen getroffen werden. Bisher gibt es keine Architekturrichtlinien und -werkzeuge, die den Entwurf einer Ökosystemarchitektur unterstützen. Dadurch fehlt hier systematisches, wiederverwendbares Wissen. Plattformanbieter müssen auf ad-hoc Entscheidungen zurückgreifen. Dies kann dann zu Problemen im Betrieb der Software-Plattformen führen, zu erhöhten Ausfallrisiken und Mehrkosten.\r\n\r\nDer Mangel an Architekturwissen manifestiert sich konkret in zwei Gruppen von Herausforderungen: Erstens fehlt eine Wissensbasis zu Architekturalternativen und zweitens fehlt es an methodischem Wissen zu Entwicklung und Betrieb von Software-Ökosystemen. Eine Architekturwissensbasis würde Orientierungshilfen zu den Bestandteilen von Software-Ökosystemen und deren Abhängigkeiten geben, während methodisches Wissen die Erstellung dieser Systeme erleichtern würde.\r\n\r\nIn der Dissertation werden diese Herausforderungen durch die Entwicklung des Frameworks SecoArc für die Modellierung von Software-Ökosystemen angegangen. Der Beitrag der Dissertation ist zweifach: \r\n1.\tDas SecoArc-Framework umfasst eine Architekturwissensbasis, die wiederverwendbare Architekturentwurfsentscheidungen\r\nvon Software-Ökosystemen enthält. Die Wissensbasis wurde entwickelt, indem das Architekturwissen bestehender Ökosysteme sowie aus existierender Fachliteratur ermittelt wurde und in einer Produktlinie für Software-Ökosysteme konsolidiert wurde. Die Produktlinie umfasst architektonische Gemeinsamkeiten und Variabilitäten von Software-Ökosystemen. \r\n2.\tDas SecoArc-Framework liefert methodisches Wissen, um die Ökosystemarchitektur in Modellen zu entwerfen und zu analysieren. Dieses Wissen wurde entwickelt, indem drei Architekturmuster identifiziert wurden. Jedes Muster erfasst unterschiedliche Beziehungen zwischen architektonischen Entwurfsentscheidungen zu den Qualitätsmerkmalen einer Ökosystemgesundheit und der Erreichung von Geschäftszielen. \r\n\r\nDie Architekturmuster und die Produktlinie wurden dazu genutzt, ein Modellierungsframework zu entwickeln und in Form eines Prototypen umzusetzen, welches einen Entwurfsprozess, eine Modellierungssprache und eine Architekturanalysetechnik umfasst. Es erleichtert das Modellieren, Analysieren und Vergleichen von Ökosystemarchitekturen.\r\n\r\nDie Ergebnisse der Dissertation wurden im Rahmen von zwei Studien evaluiert. In der ersten Validierungsstudie wurden das Framework sowie der Prototyp verwendet, um zwei alternative Ökosystemarchitekturen zu entwerfen und zu analysieren. In der zweiten Studie wurde eine Analyse von existierenden Ökosystemen basierend auf den architektonischen Variabilitäten des Frameworks durchgeführt.","lang":"ger"}],"file":[{"file_id":"35069","access_level":"closed","file_name":"Bahar_Schwichtenberg_Thesis.pdf","file_size":9125342,"date_created":"2022-12-30T22:15:15Z","creator":"bahareh","date_updated":"2022-12-30T22:15:15Z","relation":"main_file","success":1,"content_type":"application/pdf"}],"status":"public"},{"title":"VREUD - An End-User Development Tool to Simplify the Creation of Interactive VR Scenes","date_updated":"2022-01-31T13:39:38Z","publisher":"IEEE","date_created":"2021-06-21T07:54:22Z","author":[{"first_name":"Enes","id":"8447","full_name":"Yigitbas, Enes","last_name":"Yigitbas","orcid":"0000-0002-5967-833X"},{"last_name":"Klauke","id":"40915","full_name":"Klauke, Jonas","first_name":"Jonas"},{"first_name":"Sebastian","last_name":"Gottschalk","full_name":"Gottschalk, Sebastian","id":"47208"},{"full_name":"Engels, Gregor","id":"107","last_name":"Engels","first_name":"Gregor"}],"year":"2021","citation":{"apa":"Yigitbas, E., Klauke, J., Gottschalk, S., &#38; Engels, G.
