“…Calazans et al [18] defined low-quality requirements as "requirements smells" and confirmed the existence of requirements smells in the quality requirement specifications classified by ISO/IEC 25010 by analyzing 26 institutional regulations of a large public financial institution. Eugenio et al [19] extended the definition of requirement quality in the temporal dimension and developed an industrial method for analyzing the evolution of requirement quality, which is implemented in the system quality analyzer tool. Although the definition of requirement quality is constantly being refined and innovated, the applicability of requirement quality definitions has not yet been matched and modified in the field of agile development, and relevant mathematical models and assessment methods for requirement quality have not been established.…”

“…(3) The model design that integrates multiple technologies demonstrates improvements. Compared to the existing research on requirement quality definitions [15][16][17][18][19], this study innovatively adopts a modeling approach to model the seven commonly recognized requirement quality attributes in the field of requirement engineering. Mathematical formulas are used to express the definition and calculate the requirement quality, prompting a shift from qualitative to quantitative approaches in requirement quality research.…”

Agile development processes based on user stories often face issues such as incomplete, inconsistent, and inaccurate user requirements, which increase the workload of agile development teams and reduce the efficiency of product function development, ultimately resulting in the inability to respond quickly to user requirements. This paper proposes a user requirement quality assessment method based on user stories to address these problems. This method relies on the agile development process, constructs a user requirement quality assessment framework, defines a user story model and a user requirement quality model, develops seven user requirement quality assessment criteria, and designs a user requirement quality assessment process. A data experiment exploring the development of smartphone requirements is used to validate the feasibility and effectiveness of the method. The experimental results demonstrate that the method improves user requirement quality to some extent, providing an automated solution for agile development teams to enhance user requirement quality.

“…• Verification Studio supports the centralised analysis and management of the quality of different artefact types, and it is part of tool suite that also supports the management of the traceability between system artefacts (need 5). • A recent feature of Verification Studio supports the analysis of the evolution of the quality of an artefact [19], including the use of different metrics at different moments of the lifecycle of an artefact to assess its quality (need 6). For integration of ASCE and Verification Studio, we exploit the OSLC-KM technology [2], which provides generic means for tool interoperability.…”

Context and motivation]Safety-critical systems in application domains such as aerospace, automotive, healthcare, and railway are subject to assurance processes to provide confidence that the systems do not pose undue risks to people, property, or the environment. The development of safety cases is usually part of these processes to justify that a system satisfies its safety requirements and thus is dependable. [Question/problem] Although safety cases have been used in industry for over two decades, their management still requires improvement. Important weaknesses have been identified and means to assess the quality of safety cases are limited. [Principal ideas/results] This paper presents a research preview on the assessment of the quality of safety cases. We explain how the area should develop and present our preliminary work towards enabling the assessment with Verification Studio, an industrial tool for system artefact quality analysis. [Contribution] The insights provided allow researchers and practitioners to gain an understanding of why safety case quality requires further investigation, what aspects must be considered, and how quality assessment could be performed in practice.

Most safety-critical systems must undergo assurance and certification processes. The associated activities can be complex and labour-intensive, thus practitioners need suitable means to execute them. The activities are further becoming more challenging as a result of the evolution of the systems towards cyber-physical ones, as these systems have new assurance and certification needs. The AMASS project (Architecture-driven, Multi-concern and Seamless Assurance and Certification of Cyber-Physical Systems) tackled these issues by creating and consolidating the de-facto European-wide open tool platform, ecosystem, and self-sustainable community for assurance and certification of cyber-physical systems. The project defined a novel holistic approach for architecture-driven assurance, multi-concern assurance, seamless interoperability, and cross-and intra-domain reuse of assurance assets. AMASS results were applied in 11 industrial case studies to demonstrate the reduction of effort in assurance and certification, the reduction of (re)certification cost, the reduction of assurance and certification risks, and the increase in technology harmonisation and interoperability.
