Using a Requirements Modelling Language to Co-Design Intelligent Support for People Living with Dementia
Context and motivation: this research developed a new AI application to support people with dementia to maintain quality of life. Problem: the research explored methods for co-designing models of goals that users of an AI application will seek to achieve. Principal result: An effective co-design method for enabling domain experts to externalize and validate expertise about dementia care. Contribution: A co-design goal modelling method effective with dementia care workers, but still untested with experts in other domains

Using mobile RE tools to give end-users their own voice
Researchers highlight end-user involvement in system design as an important concept for developing useful and usable solutions. However, end-user involvement in software engineering is still an open-ended topic. Novel paradigms such as service-oriented computing strengthen the need for more active end-user involvement in order to provide systems that are tailored to individual end-user needs. Our work is based on the fact that the majority of end-users are familiar with mobile devices and use an increasing number of mobile applications. A mobile tool enabling end-user led requirements elicitation could be just one of many applications installed on end-users' mobile devices. In this paper, we present a framework of end-user involvement in requirements elicitation which motivates our research. The main contribution of our research is a tool-supported requirements elicitation approach allowing end-users to document needs in situ. Furthermore, we present first evaluation results to highlight the feasibility of on-site end-user led requirements elicitation

Human Activity Modelling in the Specification of Operational Requirements: Work in Progress
This paper describes our experience of integrating HCI concepts and techniques into a concurrent requirements engineering process called RESCUE. We focus on the use of a model of current human activity to inform specification of a future system. We show how human activity descriptions, written using a specially designed template, can facilitate the authoring of use case descriptions to be used in the elicitation of requirements for complex socio-technical systems. We describe our experience of using descriptions of human activity, written using the template, to support specification of operational requirements for DMAN, a system to support air traffic controllers in managing the departure of aircraft from airports. We end with a discussion of lessons learnt from our experience and present some ideas for future development of work in this area

User roles in asynchronous distributed collaborative idea generation
This paper presents the findings of an exploratory study within a real-life context that investigates participant behaviour and emergent user roles in asynchronous distributed collaborative idea generation by a defined community of users. In the study, a high-fidelity prototype of an online virtual ideas room was built and used by a Community of Interest consisting of representatives from 10 different voluntary organisations spread across Denmark. The study revealed five user roles, which the authors propose that future asynchronous distributed collaborative idea generation platforms should consider

Integrating creativity into requirements processes: experiences with an air traffic management system
Requirements engineering is a creative process in which stakeholders and designers work together to create ideas for new systems that are eventually expressed as requirements. This paper describes RESCUE, a scenario driven requirements engineering process that includes workshops that integrate creativity techniques with different types of use case and system context modeling. It reports research in which RESCUE creativity workshops were used to discover stakeholder and system requirements for MSP, a future air traffic management system to enable the more effective, longer term planning of European airspace use. The workshops were successful in that they provided new and important outputs for subsequent requirements processes. The paper describes the workshops structures and results, and answers 3 important research questions

The effect of variability modeling on requirements satisfaction for the configuration and implementation of off-the-shelf software packages
An industrial experience of the use of a method for discovering customer requirements with which to configure an off-the-shelf software package for implementation is reported. The method uses an adapted form of product variability model to provide common ground between the customer and supplier about requirements and capabilities. An associated decision support software tool guides the supplier and customer through a model-based walkthrough to discover new requirements, based on equivalent capabilities described in the product variability model. We applied the method in the work processes of the commercial provider of a software-based learning management system, and collected quantitative and qualitative data from supplier-customer interactions. Our first experiences with the method led to an increased exposure and expression of customer requirements in the customer-supplier dialogue, compared to the baseline dialogue during software package demonstrations. The paper also reports some first lessons learned to improve the method and adopt its use with other software supplier organizations
