Improv to invent and represent scenarios for Requirements: Video

Published on April 4, 2012 by in Demos, My papers

During the 2ndInternational Workshop on Creativity in Requirements Engineering (CREARE’12, Essen, Germany), we showcased how improv can be used as an experience-based design technique. Better than words, the video: In the related paper we present the expected strengths of using improv as a design technique in RE: Improv supports collaborative creativity: improv as we use it can be seen as mechanism to create novel, unexpected stories from diverging raw material, and adapts well to stakeholders groups. Interaction between players, and between the audience and the players, is key to improv. Improv is quick and cheap: given the cost of N people locked in a meeting room, improv’s immediacy makes it a very cheap tool compared to other slower techniques. Improv is flexible: the lack of fixed recording media makes it for a total flexibility, while video recording and a-posteriori editing remains possible. Improv is intuition-based: improv taps into your intuition to build stories. This neglected

Requirements for Sustainable Systems Workshop (RE4SuSy)

Published on March 16, 2012 by in My papers

REFSQ’12 conference (Essen, Germany) will host the first edition of the RE4SuSy workshop, focusing on Requirements Engineering for Sustainable Systems. It is jointly organized by Birgit Penzenstadler, Camille Salinesi and myself. I had the chance to be an author in 3 papers that will be presented there. In the first, we argue that Sustainable Systems is a complex topic, more complex that we might want to see at first sight. While existing simplifying frameworks are useful, we have to work more to integrate this complexity into our projects, not hide it under sometimes over-simplifying diagrams. The second highlight the requirements work that remains to be done around electromobility (electric-cars) and the smart grid that will manage the distribution of electricity in a near future. IT is at the heart of this new infrastructure, and while technology is nearly ready, there remain a lot of unanswered questions concerning the requirements of these systems. Finally we present

Experimenting around Sustainable Requirements for Sustainable Software

Published on February 10, 2012 by in My papers

Over the last decades, IT has become one of the leading industries worldwide. Its effects on our society and its environment are considerable. Its most obvious effects result from the production, operation, maintenance and disposal of IT infrastructure, roughly hardware. This is what the majority of “green IT” initiatives have been concerned with up to now. Yet, there is another important manner in which IT affects its environment: IT changes individual and organisational behaviour. Think of how the Internet, office automation, mobile phones, route planners and many other applications have affected the way we act (e.g., work, travel) and communicate. At the heart of IT lies software. The way software is designed (e.g., what functions it supports, which parts of its environment it interacts with, which IT infrastructure it uses and how) can have a major influence on the sustainability of the human activities involved. Such fundamental decisions are typically made during Requirements Engineering (RE),
