Definition and Use of Software Requirement Patterns in Requirements Engineering
The final quality of software products and services depends on the requirements stated in the Software Requirements Specifications (SRSs). However, some problems like ambiguity, incompleteness and inconsistency have been reported in the writing of SRSs, especially when natural language is used. Requirements reuse has been proposed as a key asset for requirements engineers to efficiently elicit, validate and document software requirements and, as a consequence, obtain SRSs of better quality through more effective engineering processes. Among all the possible techniques to achieve reuse, patterns hold a prominent position. In their most classical form, patterns describe problems that occur over and over again, and then describe the core of the solution to these problems. Software engineering practitioners have adopted the notion of pattern in several contexts, remarkably related to software design (e.g., design patterns and software architectural patterns), but also in other software development phases, both earlier and later. Following this strategy, requirement patterns emerge as a natural way to reuse knowledge during the Requirements Engineering (RE) stage. Although there have been several techniques proposed to reuse requirements, it has been observed that no concrete proposal has achieved a wide acceptance, neither any covered all the necessary elements to encourage organizations to adopt requirements reuse. As a consequence, this thesis proposes the use of Software Requirement Patterns (SRPs) as a means to capture and reuse requirements knowledge in the context of information technology projects. Following the typical context-problem-solution structure of patterns, an SRP mainly consists of: a template (solution) that may generate one or more requirements when applied in a certain project, and some information (context-problem) to identify its applicability in that project. To facilitate their use, SRPs are encapsulated inside the PABRE (PAttern-Based Requirements Elicitation) framework. The framework covers all the elements that could be critical for the adoption of a requirements reuse technique. Specifically, the framework includes: - A metamodel that describes the structure and semantics of SRPs and their organization inside a catalogue. - An SRP catalogue composed by non-functional, non-technical and functional SRPs, the functional ones being specific for the content management system domain. - A method for guiding the use of an SRP catalogue during requirements elicitation and specification, as well as another one for constructing and updating it. - An economic model to perform cost-benefit analysis on the adoption of SRPs based on return-on-investment. - The PABRE system as technological support. In order to analyse the benefits and drawbacks of the SRPs proposed in this thesis, two empirical studies have been carried out to investigate the perception of participants about requirement patterns in general and SRPs in particular. The first one is an exploratory survey addressed to information technology people with industrial experience in RE, which analyses the current state of the practice of requirement patterns approaches. The second one corresponds to a set of semi-structured interviews, focussed on the SRP approach, conducted to requirements engineers of Swedish organizations. Moreover, as it has been discovered that there are few empirical studies showing the state of the practice of requirements reuse in industry, the first study also explores the current situation of requirements reuse practices in organizations.
Requirements Engineering: Foundation for Software Quality
This volume compiles the papers accepted for presentation at the 16thWorking C- ference on Requirements Engineering: Foundation for Software Quality (REFSQ 2010), held in Essen during June 30 and July 1-2, 2010. Since 1994, when the first REFSQ took place, requirements engineering (RE) has never ceased to be a dominant factor influencing the quality of software, systems and services. Initially started as a workshop, the REFSQ working conference series has now established itself as one of the leading international forums to discuss RE in its (many) relations to quality. It seeks reports of novel ideas and techniques that enhance the quality of RE products and processes, as well as reflections on current research and industrial RE practices. One of the most appreciated characteristics of REFSQ is that of being a highly interactive and structured event. REFSQ 2010 was no exception to this tradition. In all, we received a healthy 57 submissions. After all submissions had been ca- fully assessed by three independent reviewers and went through electronic disc- sions, the Program Committee met and finally selected 15 top-quality full papers (13 research papers and 2 experience reports) and 7 short papers, resulting in an acc- tance rate of 38 %. The work presented at REFSQ 2009 continues to have a strong anchoring in pr- tice with empirical investigations spanning over a wide range of application domains.
Advancing Technology Industrialization Through Intelligent Software Methodologies, Tools and Techniques
Software has become ever more crucial as an enabler, from daily routines to important national decisions. But from time to time, as society adapts to frequent and rapid changes in technology, software development fails to come up to expectations due to issues with efficiency, reliability and security, and with the robustness of methodologies, tools and techniques not keeping pace with the rapidly evolving market. This book presents the proceedings of SoMeT_19, the 18th International Conference on New Trends in Intelligent Software Methodologies, Tools and Techniques, held in Kuching, Malaysia, from 23–25 September 2019. The book explores new trends and theories that highlight the direction and development of software methodologies, tools and techniques, and aims to capture the essence of a new state of the art in software science and its supporting technology, and to identify the challenges that such a technology will have to master. The book also investigates other comparable theories and practices in software science, including emerging technologies, from their computational foundations in terms of models, methodologies, and tools. The 56 papers included here are divided into 5 chapters: Intelligent software systems design and techniques in software engineering; Machine learning techniques for software systems; Requirements engineering, software design and development techniques; Software methodologies, tools and techniques for industry; and Knowledge science and intelligent computing. This comprehensive overview of information systems and research projects will be invaluable to all those whose work involves the assessment and solution of real-world software problems.
