Goal Orientation: it works!
Feedback on 20 years of use in business
Dr Robert Darimont - CEO, Respect-IT

Abstract

  Goal orientation is not yet the mainstream approach used in practice. However it has been proved to be a keystone to project success.
The talk will
  • shortly introduce the subset of KAOS notations and the RE processes typically followed during RE cases
  • review the kind of projects in which the use of goal orientation has been proved successful,
  • identify success factors and impediments to the adoption of goal orientation in business.
 

Short Biography

  Robert Darimont received a PhD on the formalization of refinement patterns and the formalization of RE processes from the University of Louvain under the supervision of Prof. A. van Lamsweerde. He is the founding CEO of Respect-IT, a spin-out of the University of Louvain (B). He has led a lot of medium- and large-size requirements engineering projects for more than 15 years in various domains (industry, public / private administrations). He plays a key role in the development of the Objectiver tool that supports the KAOS approach to Goal-Oriented Requirements Engineering.

iStar Extensions: Looking back and thinking about the future
Prof. João Araújo
(in collaboration with Enyo Gonçalves and Jaelson Castro)

Abstract

  Recently the iStar modelling language has evolved to a new version (iStar 2.0), where this version joins the different variations of iStar and standardises it. We believe that it is natural and necessary the core of iStar and any other language to evolve. Nevertheless, iStar has been extended many times, so it is time to research about iStar extensions. Extending a modelling language is to add new constructs or modify the old ones. According to the way new concepts are proposed, an extension can be developed using a light-weight or heavy-weight strategy.
   The first iStar extension was proposed 16 years ago (2001 - 2017). So, this talk reviews the existing iStar extensions by presenting a quantitative analysis and the perspectives of iStar researchers. Some challenges will be discussed such as extension mechanisms and a process to guide iStar extensions.

Istar in practice: Scaling up model acquisition and other war stories
Aditya Ghose

Abstract

  In reflecting on experiences from practical applications of i*, the hardest challenge we've had to face was that of scaling up model acquisition. I will describe a short-term fix that worked in the instance of a project with a government agency, and a more principled approach that we have examined in the past few years. I will also recount, time permitting, experiences from the use of i* in a project that addressed the automation of strategic alignment checking.
 

Short Biography

  Aditya Ghose is Professor of Computer Science at the University of Wollongong, and Director of the Decision Systems Lab (and the associated Centre for Oncology Informatics). Ghose holds a PhD and Msc in Computing Science from the University of Alberta (Canada) and a Bachelor of Computer Science and Engineering from Jadavpur University (India). In addition to conceptual modeling and RE, he works on business process management, service science, software analytics and medical informatics. Much of this work is underpinned by his long-standing interest in formal knowledge representation and reasoning, and agent systems. He works with (and has been funded by) some of the world's largest IT companies, as well as by agencies such as the Australian Research Council, the CRC for Smart Services, the Canadian NSERC, the Japanese AITEC and others. He is a Fellow of the Institution of Engineers (Australia) and President of the Service Science Society of Australia.
