Call for Papers RIGiM'124th International Workshop on Requirements, Intentions and Goals in Conceptual Modeling (RIGiM'12) in Conjunction with the 31st International Conference on Conceptual Modeling (ER'12) Florence, Italy 15-18th October, 2012 Paper submission deadline: April Web site: https://sites.google.com/site/rigim12/ Organizers
** Keynote **John Mylopoulos: Requirements in the Land of Adaptive Systems Adaptive systems of any sort (software, hardware, biological or social) consist of a base system that carries out activities to fulfill some requirements R, and a feedback loop that monitors the performance of the system relative to R and takes corrective action if necessary. We adopt this view of adaptivity for software-intensive systems and sketch a framework for designing adaptive systems which starts with requirements models, extends them to introduce control-theoretic concepts, and uses them at run-time to control the behaviour of the base system. We also present preliminary results on the design of adaptive systems-of-systems where the main problem is how to maintain alignment between a collection of independently evolving systems so that they continue to fulfill a set of global requirements. The presentation is based on joint research with Vitor Souza, Alexei Lapouchnian, Fatma Aydemir and Paolo Giorgini all with the University of Trento. Scope and TopicsThe use of intentional concepts, the notion of "goal" in particular, has been prominent in recent approaches to requirements engineering. Goal-oriented frameworks and methods for requirements engineering (GORE) have been keynote topics at requirements engineering conferences, and at major software engineering conferences. What are the conceptual modelling foundations in these approaches? Traditionally information system engineering has made the assumption that an information system captures some excerpt of world history and hence has concentrated on modeling information about the Universe of Discourse. This is done through conceptual modeling that aims at abstracting the specification of the required information system, i.e., the conceptual schema, from an analysis of the relevant aspects of the Universe of Discourse about which the user community needs information. This specification concentrates on what the system should do, that is, on its functionality, serving as a prescription for system construction. Whereas conceptual modelling allowed system developers to understand the semantic of information and led to a large number of semantically powerful conceptual models, experience demonstrates that it often fails in supporting the delivery of systems that were accepted by the community of users. Indeed, a number of studies have shown that many systems fail due to an inadequate understanding of the requirements they seek to address. Furthermore, the amount of effort needed to fix these systems has been found to be very high. To correct this situation, it is necessary to view information systems as fulfilling some purpose in an organisation. Understanding purpose, goals, and intentions is a necessary condition for the design of successful systems. Conceptual modelling therefore needs to go beyond functionality requirements that specify the 'what', to encompass the deeper contextual understanding of the 'whys'. The 'why' questions are answered in terms of organisational objectives and the desires and motivations of stakeholders and participants. Modelling the 'whys' helps focus requirements elicitation, validation, and specification. Goal-oriented approaches in requirements engineering have emerged to meet this expectation. The Workshop aims to provide a forum for discussing the interplay between requirements engineering and conceptual modeling, and in particular, to investigate how goal- and intention-driven approaches help in conceptualising purposeful systems. What are the fundamental objectives and premises of requirements engineering and conceptual modelling respectively, and how can they complement each other? What are the demands on conceptual modelling from the standpoint of requirements engineering? What conceptual modelling techniques can be further taken advantage of in requirements engineering? What are the upcoming modelling challenges and issues in GORE? What are the unresolved open questions? What lessons are there to be learnt from industrial experiences? What empirical data are there to support the cost-benefit analysis when adopting GORE methods? Are there applications domains or types of project settings for which goals and intentional approaches are particularly suitable or not suitable? What degree of formalization and automation or interactivity are feasible and appropriate for what types of participants during requirements engineering? e.g., business domain stakeholders, requirements modelers, ontology engineers, etc. TopicsTopics of interest include, but are not limited to:
Format and DurationWe aim for a highly interactive forum. Discussants and discussion facilitators will be formally appointed for each paper and session, respectively, to ensure an atmosphere of productive interaction. The working language is English. The workshop duration is three sessions (1.5 hours each) Workshop proceedings will be published by Springer-Verlag in the LNCS series.

31st International Conference on Software EngineeringTutorial on Goal Oriented Requirements EngineeringVancouver, Canada, May 16-24, 2009Authors: Jaelson Castro, Universidade Federal de Pernambuco - UFPE, Brazil; Eric Yu, University of Toronto, Canada; Neil Maiden, City University, United Kingdom Held on: Tuesday the 19th (morning and afternoon) Abstract: Growing experience with Goal-Oriented Requirements Engineering GORE has shown that goals are among the key forces for requirements elicitation, modelling, analysis and evolution. Goals capture stakeholder purposes which are related to functional and non-functional requirements. This tutorial reviews the history of ideas and research related to GORE, providing a review of some well-known techniques such as NFR, GBRAM and KAOS, and giving special emphasis on i*. In particular, we show that understanding the social and organizational context is critical to the success of many systems today. By explicitly modelling and analyzing strategic relationships among multiple actors, the i* approach incorporates rudimentary social analysis into a systems analysis and design framework. Actors depend on each other for goals to be achieved, tasks to be performed, and resources to be furnished. A notion of softgoal 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. During systems design, actors explore alternative configurations of dependencies to assess their strategic positioning in a multi-agent, social context. GRL, a version of i*, is part of the new ITU-T Z.151 international standard. This tutorial will introduce, explain and demonstrate the i* framework with examples, and describe how to use it during the early stages of the requirements process. Attend this tutorial if you are a Practicing Requirements Engineer who wants to learn goal oriented techniques, an Academic who wants to explore how goal orientation fits into requirements engineering, or a Project leader and Manager who wants to understand how goals can be part of the requirements process. Invited Speakers: Daniel Amyot, University of Ottawa, Canada • Goal-oriented Requirement Language (GRL) and its Applications Xavier Franch, UPC Barcelona, Spain • Using i* for OTS Software Component Selection Anna Perini, FBK IRST, Italy • Understanding the Requirements of a Decision Support System for Integrated Production in Agriculture |

The Z.151 - User Requirements Notation (URN) standard has been approved by the International Telecommunications Union's
Telecommunication Standardization Sector (ITU-T). URN is a language consisting of Use Case Maps and GRL (Goal Requirement Language), a variant of the i* Framework. The standard was approved at the ITU-T SG17 meeting in Geneva on November 13, 2008, together with several companion standards including Z.111, which defines the URN meta-metamodel, and Z.110 and Z.450, which both cite URN. Thank you to everyone for their hard work in this effort. The Z.151 draft document is available at: http://jucmnav.softwareengineering.ca/twiki/bin/view/UCM/DraftZ151Standard Results of the approval process: Z.151 - User Requirements Notation (URN) - Language definition Z.111 - Notations and Guidelines for the Definition of ITU-T Languages Z.110: Criteria for use of formal description techniques by ITU-T Z.450 - Quality aspects of protocol-related Recommendations |
