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 (2002), London (2005), Recife (2008), Hammamet (2010), Trento (2011), Valencia (2013), Thessaloniki (2014), Ottawa (2015), Beijing (2016) and Essen (2017), it is time for another meeting focusing on i*(iStar), GRL, Tropos, Techne, and related frameworks, where researchers can exchange ideas, compare notes, and hopefully forge new collaboration with like-minded folk.
We cordially invite you and members of your group to join us at the Eleventh International i* Workshop. The 2-day workshop will be held in Tallinn, Estonia, 11-12 June, 2018, as a co-located event with the 30th International Conference on Advanced Information Systems Engineering (CAiSE’18).

The 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
Ontological foundations
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

=== Submissions ===
Contributions should be maximum 6 pages in single column LNCS format, describing current and ongoing research related to the i* framework. This year, we welcome four types of papers: technical papers, empirical evaluation and experience reports, position papers, and tool papers.
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.
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 istarwiki@dbis.rwth-aachen.de if you require a new user name and password for the wiki.
All submissions should be uploaded to easychair (https://easychair.org/conferences/?conf=istar2018).
All submissions will be peer-reviewed and accepted works will be published in the CEUR Workshop Proceedings Series.
