“…This approach, based on GORE and GAR (Generic Autonomy Requirements), has the objective for eliciting, specific autonomy requirements, and defines assistive and possible alternative objectives for self-adaptive systems. Other approaches were proposed, such as goal-based like FLAGS [12] and Tropos4AS (Tropos for Adaptive System) [17], a recent agent-based approach.…”

Background: Systems whose requirements change at a rate that necessitates adaptation without human intervention are called self-adaptive systems, and they have the ability to adjust their behavior autonomously at run-time in response to their environment’s evolution. Samples of applications that require self-adaptation include Smart home systems and environmental monitoring. However, self-adaptivity is often constructed in an ad-hoc manner. Methods: In this paper, the authors present a pattern-based specification language for self-adaptive systems. Its semantics are presented in terms of fuzzy logic. Thus, enabling a meticulous processing of requirements, in order to permit the formulation of self-adaptive requirements accurately, thereby facilitates the design of systems that are flexible and responsive to adaptation in a systematic manner. Results: To show the applicability and effectiveness of our language, the authors apply it to two case studies. One case study reviews the Smart fridge in ambient assisted living and the second case study is focused on an ambulance dispatching system using a developed support tool.

“…There are different forms to present an iStar extension [9], but all of them introduce new concepts to iStar. For example, a set of extensions described in detail the new concepts and its representations in the iStar metamodel and concrete syntax (see works of Ali, Dalpiaz and Giorgini [1] and Morandini et al presented in [14]). This kind of extensions describes how the new concepts were introduced and how to use them.…”

“…TROPOS4AS is an example of iStar extension, it was proposed by Morandini et al in [14]. It models characteristics of adaptive systems in Tropos, proposed by Bresciani et al [3], providing conceptual models, a graphical language, and its semantics, to enable capturing requirements needed for defining and driving adaptation.…”

iStar has been extended since its initial proposal in the 90's. It is worth noting that since 2016 the language notation is under standardisation. However, new extensions continue to be proposed. The search for previous extensions and its constructs can be a starting point in the proposal of new ones. So, to ease the identification of the previous extensions and its constructs is essential to next proposals. Motivated by this situation, the objective of this paper is to present a catalogue of iStar extensions. The extensions and their constructs were identified from a systematic literature review, which identified that 96 extensions had been proposed until 2016. The results suggest that catalogue is important during future iStar extensions proposal.

“…Coupled with the INCOSE 2025 Vision, this research presents empirical evidence of the nexus between the correlation relationship of requirements linguistic quality and system performance. The quality of RE documentation, along with requirements usability represents vital parameters for the acceptability of correct systems . While there is research on addressing usability treatment during the development process, the problem of identifying and resolving linguistics defects in system requirement documents ahead of time to improve stakeholder decisions and systems performance is yet unaddressed.…”

“…Existing research indicates that errors during RE processes, literature gaps, linguistic defects, and requirements ambiguities contribute to system deficiencies, rework and unsatisfactory system performance . In addition to quality, attributes of requirements usability represent vital parameters for the acceptability of correct systems . Ref.…”

This paper focuses on the Requirements Engineering process's vital role during systems development as the preparatory point and critical foundation of Systems Engineering. This paper proposes a framework for structuring decisions, based upon the INCOSE Decision Management Process that improves decisions early in the System Life Cycle. This paper introduces and applies the Nexus Engineering Execution Generation (NEX GEN) framework, a novel and unique capability to improve requirements by enabling a prediction of their impact on expected systems' performance to gain efficiencies in budget and acquisition. Using this framework defines requirements in a quantitative manner to determine documented requirement issues. Regression analysis indicated a statistically significant relationship between the predictor variable of ambiguity (linguistic quality attribute) and the response variable of system performance (usability metric). This study provides a framework and metrics as a complementary method for the development of requirements in a theoretical manner for the reflective practitioner. This framework is demonstrated through multiple federal system program case studies.
