Feedback communication channels allow end-users to express their needs, which can be considered in software development and evolution. Although feedback gathering and analysis have been identified as an important topic and several researchers have started their investigation, information is scarce on how software companies currently elicit end-user feedback. In this study, we explore the experiences...
Existing modeling approaches in requirements engineering assume that stakeholder goals are static: once set, they remain the same throughout the lifecycle of the project. Of course, such goals, like anything else, may change over time. In earlier work, we introduced Evolving Intentions: an approach that allows stakeholders to specify how evaluations of goal model elements change over time. Simulation...
Developers maintaining safety-critical systems need to assess the impact a proposed change would have upon existing safety controls. By leveraging the network of traceability links that are present in most safety-critical systems, we can push timely information about related hazards, environmental assumptions, and safety requirements to developers. In this work we take a design science approach to...
Security attacks on medical devices have been shown to have potential safety concerns. Because of this, stakeholders (device makers, regulators, users, etc.) have increasing interest in enhancing security in medical devices. An effective means to approach this objective is to integrate systematic security requirements elicitation and analysis into the design and evaluation of medical device software...
Context and Motivation Natural language processing has been used since the 1980s to construct tools for performing natural language (NL) requirements engineering (RE) tasks. The RE field has often adopted information retrieval (IR) algorithms for use in implementing these NL RE tools. Problem Traditionally, the methods for evaluating an NL RE tool have been inherited from the IR field without adapting...
Classifying requirements into functional requirements (FR) and non-functional ones (NFR) is an important task in requirements engineering. However, automated classification of requirements written in natural language is not straightforward, due to the variability of natural language and the absence of a controlled vocabulary. This paper investigates how automated classification of requirements into...
Capturing high-level requirements in a human readable but formal representation suitable for analysis is an important goal for GE. To that end we have augmented an existing controlled-English modeling language with a new controlled-English requirements capture language to create the Requirements Capture frontend of the ASSERT(TM) tool suite. Requirements captured in ASSERT can be analyzed for a number...
Requirements elicitation is the initial step of the requirements engineering process and aims at gathering all the relevant requirements through the direct or indirect interactions between requirements analysts and stakeholders. Even if the requirements elicitation problem is not new and has been approached many times over the years, it is still considered one of the most challenging of the requirements...
Systematising requirements reuse is a key step to raise the efficiency and maturity level in Requirements Engineering (RE), which is even better when centred on a repository of common artefacts like templates and patterns that allow people to build and share a strong reference framework. The aim of this tool demo is to show how to deploy an approach combining a local library for each analyst and a...
We present CoSTest, a tool that supports the validation of Conceptual Schemas by using testing. The tool implements techniques for transforming instantiations from a Requirements Model into test case implementations by supporting a Model-driven architecture.
Respecify is a new web-based requirements authoring tool using constrained natural language (CNL) to guide the authoring process and drive the creation of alternative views that elucidate the complexity of specifications, thus reducing the occurrence of certain types of requirements quality defects. This tool demo motivates Respecify's existence, its key features, and evaluates its current use in...
Dependability of cyber-physical systems rests crucially on the fidelity of formal models to their real-world physical subject matter; yet little explicitly focused research has been devoted to this concern. This talk sketches the concern and commends it as a focus for future research in the RE community.
Prioritization of non-functional requirements (NFRs) is a research field that needs more attention. We demonstrate ARRoW, a novel approach for automatic runtime reappraisal and update of the weights of NFRs given new evidence collected from the environment during the execution of the system. In this paper, we showcase how ARRoW is used in an substantial industrial case study. Our results shows how...
Thanks to the advent of interactive technologies, education institutions are looking for innovative teaching methods to increase the engagement and reach of students. Besides the uprise of MOOCs, gamification has been shown to produce positive results when it comes to increasing people's engagement and interest in conducting tasks. Unfortunately, the application and benefits of these technologies...
Requirements Engineering (RE) is closely tied to other development activities and is at the heart and foundation of every software development process. This makes RE the most data and communication intensive activity compared to other development tasks. The highly demanding communication makes task switching and interruptions inevitable in RE activities. While task switching often allows us to perform...
Gamification has been applied in software engineering contexts, and more recently in requirements engineering with the purpose of improving the motivation and engagement of people performing specific engineering tasks. But often an objective evaluation that the resulting gamified tasks successfully meet the intended goal is missing. On the other hand, current practices in designing gamified processes...
