Both researchers and practitioners have a profound interest in the introduction of new technologies into organizations. Often, the question is to what extent business processes will or have in fact improved due to such innovations, e.g. in terms of efficiency or speed. In this tutorial, we introduce and explain an innovative method to carry out such impact analyses. The method is based on a conceptual model of the business process of interest, empirical data on its actual performance over time, and simulation techniques for methodological rigour.

Prof. Shamkant B. Navathe, Georgia Institute of Technology, USA
Digital services are driving business and public organizations towards a Digital Transformation, which demands a deep change in how organizations perform and interact with customers. Several factors hinder this path: complexity in digital service provisioning, inherent challenges of paper-based, natural-language service contracts, with corresponding ambiguity about contractual terms, and informational (and business) asymmetries across the contracting parties. While Service Oriented Architectures (SOA) are paving the way to face the main IT-related issues, a number of challenging business- and contract-related aspects need to be identified. Conceptual models play a pivotal role in widening the horizon of SOA by clarifying the interdependencies between business artifacts (e.g. contracts) and technical infrastructure, which is essential to establish a manageable relationship among clients, providers and involved third parties.
Antonella Longo holds a degree in Computer Engineering and a Ph.D. in Information Engineering. Currently she is an assistant professor at the Department of Engineering for Innovation, University of Salento (Lecce), Italy, where she works in Set-Lab.

Nov. 16 (Wed), 11:00-12:30, International Conference Room (Int'l)
Prof. Aditya Ghose, University of Wollongong, Australia
There is a growing body of evidence that certain classes of models (enterprise architecture models, goal models as well as process and service models, for instance) are amenable to automated acquisition from readily available enterprise data. These techniques seek to mine useful "first-cut" models from the available data, which can be subsequently edited and refined by analysts, thereby easing the model acquisition bottleneck (there are other benefits, including the ability to improve model quality, and the use of models as dashboard artefacts. This tutorial will provide a timely exposition to these techniques whose importance is likely to grow significantly in the near future.

Prof. Bernhard Thalheim, Christian Albrechts University, Germany
Models are a central instrument in many scientific disciplines and engineering. They are utilised for different purposes and in different functions depending on the specific utilisation scenario. Computer science and engineering have developed their own understanding of the notion of the model, their own approaches to modelling activities, and their specific understanding of modelling. The bandwidth spans iconic models (e.g. chip models), analogous models (e.g. architecture models), symbolic models (e.g. diagrams for many different applications), and formal models depending on abstraction, focus and scope. The tutorial introduces a novel, very general notion of the model, presents techniques for modelling, and discusses the art, technology, science, and culture of modelling.
The tutorial is based on the survey on models and their systemaisation in more than 2 dozen disciplines (http://www.degruyter.com/view/product/448425).

Prof. Sjaak Brinkkemper, Utrecht University, the Netherlands
90% of agile practitioners employ user stories for capturing requirements. Unfortunately, however, 50% of real-world user stories contain easily preventable errors that sabotage their potential. To alleviate this problem, the presenters of this tutorial have created methods, theories and tools that support creating better user stories. During this 3-hour tutorial you will learn the basics of creating user stories and how to improve their quality using the Grimm Method and supporting tools, providing the knowledge and resources to start generating conceptual models from a set of user stories. Please send your own English user stories for entering in the tooling to firstname.lastname@example.org

Prof. Ilia Bider, Stockholm University, Sweden, and
Prof. Martin Henkel, Stockholm University, Sweden
Modeling skills consist of two components: (1) formal - ability to depict a model using a modeling language; (2) informal - ability to dissect the reality to be modeled. The latter is difficult to acquire in the classroom environment, apprenticeship being a suitable form for learning. The tutorial presents a reasonable approximation to apprenticeship using a multi-media presentation of a business case to be used in modeling courses. The concept has been tested in practice and appreciated by students. What is more, it can be implemented using limited resources by teachers themselves.
For a long time, Ilia Bider has actively combined research activities with practical work, in the end settling down in the academia as a Lecturer at a Department of Computer and Systems Sciences (DSV) of Stockholm University to reflect on his practical experience and, if possible, transfer the knowledge acquired to the younger generation. Having background in both engineering (MS from a Moscow Technical University), and science (PhD from the Swedish Royal Institute of Technology), he worked in practice in different capacities, such as programmer, bug-fixer, group and project leader, technical and business consultant, functioning as an employee for others, and as a co-founder of a Swedish consulting business called IbisSoft. He used his practical experience as inspiration for research, and his practice as a test-bed for new research ideas. Most of his published works (rising to about 70) are, in one way or another, connected to his practical work.
Martin Henkel works as associate professor at the department of computer and systems sciences, Stockholm University. Martin earned his PhD from The Royal Institute of Technology (KTH) in 2008 in the area of service oriented information systems. As a member of several international program committees Martin engages in the research areas enterprise modeling, service oriented computing, business value modeling and enterprise capability design.
