iStar 2019

12th International i* Workshop
Salvador, Brazil
November 4th, 2019

In the last decades a growing number of groups around the world have been using the i* (iStar) modelling framework in their research on early requirements engineering, business process design, organization modelling, software development methodologies, and more.

Following successful workshops in Trento/Italy (2002), London/United Kingdom (2005), Recife/Brazil (2008), Hammamet/Tunisia (2010), Trento/Italy (2011), Valencia/Spain (2013), Thessaloniki/Greece (2014), Ottawa/Canada (2015), Beijing/China (2016), Essen/Germany (2017), and Tallinn/Estonia (2018), the Twelfth International i* Workshop will take place in Salvador, Brazil, on 4 November 2019, as part of the 38th International Conference on Conceptual Modeling (ER 2019).

As with previous editions, the objective of the workshop is to provide a unique opportunity for researchers in the area to exchange ideas, compare notes, promote interactions, and forge new collaborations.

Keynote - Inter-Organizational Data Sharing: From Goals to Policies to Code

Joint keynote with MREBA

Matthias Jarke

Information Systems, RWTH Aachen University & Fraunhofer FIT


The growing interest in machine learning from a host of heterogeneous internal and external data sources has led to a renewed interest in the question of data exchange. Examples include recent studies on ontologies of data exchange from different perspectives, specification languages and model-driven code generation for remote data usage control, automation of schema and data transformation across vastly different data models, and conceptual modeling of related issues such as IT security and privacy, but also of the “data to knowledge pipeline” in which machine learning is combined with existing organizational or technical knowledge.

Especially public and commercial organizations have – on the one hand – a strong interest to exploit all available information in optimizing their organizational goals, but – on the other hand – an equally strong interest in protecting their core competitive knowledge. In Europe, this debate is happening under the label of “data sovereignty”, the ability to keep full control about your data while participating and profiting from data sharing for mutual advantage.

The talk will give an overview of the current status and future challenges in this field, addressing both important technical results and political trends. To increase coherence between the identified partial results which come from many disjoint communities, it will further try to embed them into a coherent picture starting from an i*-based analysis of the strategic setting and its positioning in organizational analysis and business analytics settings.

Short Bio

Matthias Jarke is Professor of Information Systems at RWTH Aachen University, Germany, and Scientific Director of the Fraunhofer FIT Institute for Applied Information Technology. He received his Doctorate from Hamburg University and served on the faculties of New York University and the University of Passau prior to joining RWTH Aachen University in 1991. His research focus is meta modeling and information integration in cooperative IS applications in engineering, business, and culture. Currently, he is co-speaker of Germany’s large-scale interdisciplinary national Excellence Cluster “Internet of Production” which investigates worldwide controlled information sharing and model-assisted machine learning in a broad range of production-related issues. Matthias Jarke has served as Chief Editor of “Information Systems”, the oldest journal within the database field, on editorial boards of journals such as IEEE-TSE, ACM-TOIS, ACM TMIS, and as program chair of international conferences including VLDB, EDBT, CAiSE, ER, and SSDBM. As president of the GI German Informatics Society, he coordinated the first German national “Science Year of Informatics in 2006 from which e.g. the annual Digitalization Summit of the German Chancellor emerged. Jarke serves on numerous national and international boards and advisory committees, and is elected member of the acatech National Academy of Science and Engineering, as well as Fellow of the ACM and the GI.

Call for Papers

Abstract submission: June 23rd, 2019

A growing number of groups around the world have been using the i* (iStar) modelling framework in their research on early requirements engineering, business process design, organization modelling, software development methodologies, and more. The workshop is the ideal venue where researchers can exchange ideas, compare notes, and hopefully forge new collaboration with like-minded folk. Contributions on related frameworks, such as GRL, Tropos, and Techne, are welcom.

We cordially invite you and members of your group to join us at the Twelfth International i* Workshop. The one-day workshop will be held in Salvador, Brazil, on 4 November 2019, as part of the 38th International Conference on Conceptual Modeling (ER 2019).

Topics of interests include, but are not limited to:

  • Adaptive requirements-driven systems
  • Agent-oriented systems development
  • Business intelligence and data analytics
  • Business modeling
  • Business process analysis and design, reengineering
  • Business, service, and software ecosystems
  • Enterprise, systems, and organizational architecture
  • Evaluation, verification and validation
  • Experience reports and case studies
  • Evolution, adaptation, and system dynamics
  • Formalizing or extending iStar 2.0
  • i* modeling techniques and metamodels: i* modeling concepts, variations and extensions
  • Knowledge management
  • Law and regulatory compliance
  • Mobile and cloud requirements engineering
  • Model analysis and contextual reasoning
  • Networking or integration with other modeling languages or techniques
  • Novel applications of i*
  • Ontological foundations
  • Requirements engineering
  • Scalability and uncertainty in modeling
  • Security requirements engineering, privacy, and trust
  • Socio-technical systems
  • Software engineering processes and organizations
  • Strategy modeling and business model innovation
  • Tools, visualization, and interaction
  • Variability and personalization

Submission instructions:

Contributions should be in English, with a maximum of 6 pages in single column LNCS format, describing current and ongoing research related to the i* framework.

Submissions should provide an overview of the research objectives and describe contributions, including any related tools and evaluation experience. Contributions should outline ongoing and future work and provide key references.

In particular, tool papers should include references to download information, documentation, and system features. We encourage those submitting a tool paper to create or update a page on the i* wiki. Contact if you require a new user name and password for the wiki.

All submissions should be uploaded to EasyChair: When submitting, select the "The 12th International i* Workshop" track.

All submissions will be peer-reviewed and accepted works will be published in the CEUR Workshop Proceedings Series (confirmation pending).
