Social Modeling for Requirements Engineering: Trends and Challenges
The last fifteen years have seen a new approach to the requirements challenge, the so called Social Perspective. We argue that in order to arrive at systems requirements, one should examine and understand the relationships among social actors. Rather than focusing of behavioral properties of the software, we should ask how the system will advance the relation that some actors have in relation to other actors. In this talk we describe the i* (iStar) approach proposed by Eric Yu, which incorporates rudimentary social analysis. Actors depend on each other for goals to be achieved, tasks to be performed, and resources to be furnished. A notion of soft-goal is used to deal systematically with quality attributes, or non-functional requirements. Dependencies among actors give rise to opportunities as well as vulnerabilities. Networks of dependencies are analyzed using a qualitative reasoning procedure. Social perspectives on computing have provided much insight. We review research that applies, adapts, extends, or evaluate the social modeling concepts and approaches. We also raise research challenges for our community.

Jaelson Castro has been a professor at the Federal University of Pernambuco (UFPE), Brazil, where he leads the Requirements Engineering Laboratory (LER), since 1992. He earned his Ph.D. in 1990 from Imperial College, London. His research interests include requirements engineering, agent-oriented development, aspect-oriented development, model-driven development and software product lines. Prof. Castro serves on the editorial boards of the International Journal of Agent-Oriented Software Engineering (IJAOSE) and Requirements Engineering Journal (REJ). He acted as editor in chief of the Journal of the Brazilian Computer Society (JBCS). He has also contributed to the organization of several events, including iStar 2008, RIGIM 2009, iStar2010, WGBP 2010.

Creative thinking as information discovery
Creativity has been subject of considerable research over the last 60 years. More recently results of this creativity research have been used to describe and support the specification and design of information systems. This keynote will report results from a decade of research that has applied creativity models to design systems in domains ranging from air traffic management and food information traceability to reflective learning. It will make design and economic cases for designing and using information systems as creative activities, and report results from use of creativity techniques and software tools in the reported domains. It will advocate a model of creativity as information discovery applied to the design of information systems.

Neil Maiden is Professor of Systems Engineering, Head of the Centre for Human-Computer Interaction Design and academic lead of the Centre for Creativity in Professional Practice at City University London. He received a PhD in Computer Science in 1992. He is and has been a principal and co-investigator on numerous EPSRC- and EU-funded research projects including SIMP, CREWS, BANKSEC, SeCSE, APOSDLE, TRACEBACK, S-Cube, MIRROR and CHOReOS, with a total value of £2.5million. His research interests include establishing the requirements for complex socio-technical systems, scenario-based design, service-oriented systems and cloud computing, goal modelling, and technology-enhanced creative design. He also investigates new ways of delivering results from these research areas into practice. Neil has published over 150 peer-reviewed papers in academic journals, conferences and workshops proceedings. He was Program Chair for the 12th IEEE International Conference on Requirements Engineering in Kyoto in 2004. He is on the Editorial Boards of the IEEE Software and Requirements Engineering Journal and a former member of the Editorial Board for IEEE Transactions of Software Engineering. He is also the Editor of the IEEE Software's Requirements column. His details are available at http://www-hcid.soi.city.ac.uk/pNeilmaiden.html

Human-Machine interfaces designed for all: universal theoretical principals and operational telecom industry
Universal Design is about a design philosophy. It aims at giving access to everybody without implying the use of assistive technologies. First, it’s a usability question: how to adjust Machine proposals in adequacy to Human capacities, in order to aim at a simple and efficient way of interaction. Second, it’s a multimodal question: how to enable sequential and parallel interaction, how to deal with haptic, audio, and visual feedback and feedforward. Third, it’s an adaptative question: taking into account user activities, in order to adjust usability. It’s all about social inclusion and equality thematic. As designers, we have to take into account human being diversity. Everyone must have an easy access to services and society. Elderly people, disabled people, children, foreigner with different languages, different cultural customs, beginner, skilled user... Everybody has to be able to access to our products and services. Specific development is not an economic solution, and a common unique shared interface is not possible for such diversity. We have to find other ways. Universal Design is not a dream. Even if it’s a huge conceptual approach, it is feasible, more specifically in ICT (Information and Communication Technologies) domains.

As ergonomist and cognitive psychologist, Denis Chêne has made some evidence for this, through accessible design for all TV prototypes, through design for all mobile phones, respect of accessibility guidelines through normalization activity, through web auditing tool (www.ocawa.com) and new kind of telecommunication principles as haptic broadcasting, and Total conversation services (www.reach112.eu).
He leads Accessibility research project in Orange Lab’s for 10 years now and try to contribute, with all his team to universal design industrialization.

Application of SOA concepts for Telecommunications "The Orange Caribbean SOA program"
In today’s highly competitive Telecommunications market, operational excellence is one of the key differentiator to provide best quality of service to customers and one of the most important factors influencing the overall profitability of Telecom operators. Technical environment and information systems are becoming more and more complex when portfolio of services is always increasing in diversity. Keeping under control systems & applications to run business processes in an always more efficient and flexible way, is a day after day challenge. Recognizing the influence of Information System agility and robustness in business performance, Orange Caribbean decided few months ago to launch a Service Oriented Architecture program. This paper details the “state of the art” SOA implementation managed within Orange Caribbean combining the reusability of legacy systems with the deployment of robust and fully controlled set of service oriented components. All these components are interacting and exchanging information using the semantic field of the Orange Caribbean Enterprise Data Model. First results are illustrated by the new Webcare application launched by Orange Caribbean on January 2011.
