CARO: A Conflict-Aware Requirement Ordering Tool for DevOps
No full textRequirement prioritization is an inherently important step in the DevOps framework. Unfortunately, the prioritization process often disregards the non-functional requirements and the possible conflicts among them. This implies that unresolved dependencies and conflicts would be identified at integration time only, which may lead to major refactoring issues. We introduce CARO a new tool that generates an ordering among the requirements based on conflicts and dependencies among the requirements. The tool provides a quantitative risk evaluation framework along with risk mitigation strategies based on conflicts and dependencies among the requirements
NFR-aware prioritization of software requirements
No full textNon-functional requirements (NFRs) play a significant role in the software development process. However, the classical requirement prioritization methods for incremental software development, typically, consider the attributes of functional features only, often neglecting the non-functional constraints. This might lead to catastrophic defects in the system design, as the conflicts among the NFRs are ignored. In this paper, a novel prioritization approach for functional requirements (FRs) is introduced within the incremental software development process. The proposed approach considers the conflicts among NFRs, in the prioritization process, to minimize the incon sistencies of software development. The devised NFR-aware prioritization algorithm can be tuned according to the weights that the analyst assigns to NFR conflicts and FR-NFR dependencies. We have assessed our prioritization approach using available requirements data sets and have compared the results in different scenarios
Dynamic Prioritization of Software Requirements for Incremental Software Development
No full textRequirements keep changing within an evolving business environment. In incremental software development, where functionalities are identified and delivered incrementally, a need is felt toward capturing and analyzing the impact of the changes in the system development process. This may require refactoring the order of the development of the system components based on newly added dependencies and conflicts among functional and non-functional requirements. In this paper, we propose a dynamic framework that re-prioritizes the requirements based on newly added (and updated) requirement dependencies and conflicts. We also provide an effective tool for our framework that supports software developers during incremental delivery within a changing business environment
Requirement-oriented risk management for incremental software development
No full textIn incremental software development (ISD) functionalities are delivered incrementally and requirements keep on evolving across iterations. The requirements evolution involves the addition of new dependencies and conflicts among functional and non-functional requirements along with changes in priorities and dependency weights. This, in turn, demands refactoring the order of development of system components to minimize the impact of these changes. Neglecting the non-functional constraints in the software development process exposes it to risks that may accumulate across several iterations. In this research work, we propose a risk management framework for ISD processes that provides an estimate of risk exposure for the project when functional features are frozen while ignoring the associations with non-functional requirements. Our framework proposes suitable risk reduction strategies that work in tandem with the risk assessment module. We also provide a tool interface for our risk management framework

A species of Termitodius with the pronotal paramedian costa having the anterior lobe elongate in dorsal view and anteriorly sloping in lateral view (Fig. 5–6), posterior part of discolateral pronotal costa absent medially, elytra intercostal areas entirely with transverse wrinkles, the nearly globe-like caudal bulbs on the elytra, and in distribution (Mexico and Guatemala). Type. Holotype male and allotype female: “ México: Lacanjá-Chansayab, Selva Lacandona, Chiapas, 25-I-1977, P. Reyes, col., in nido de Coptotermes af. testaceus (Lin.), selva alta perennefolia, alt. 350m. ” Reyes-Castillo and Martínez (1979) state the holotype is deposited in the collection of P. Reyes, now deposited in IEXA (not examined). Materials examined. MEXICO: Chiapas: Lacania-Chansayab, 28-I-1977, P. Reyes-C. Col. selva alta perennifolia, alt. 350 m, en Hormiguero de Coptotermes (6 paratypes CMNC from Howden and Martínez collections; 1 paratype CEMT; 1 paratype FSCA). GUATEMALA: Suchitepéquez: Patulul, Los Tarrales Private Reserve; 1000m; 14°31.942′, −91°08.799′; w/termites under bark; 8.VII.2009; M.J. Paulsen (1 UNSM). Distribution. Termitodius chaki is distributed in the Mexican transition zone at the Chiapas Highlands province, and in the Veracruzan province of the Mesoamerican dominion of the Brazilian subregion (Fig. 33). Comments. “ Termitodius chaki R&M” illustrated in Galante et al. (2003) is not a Termitodius, it is a new species of Nanotermitodius Howden, 2003, that is currently being described. This Oaxacan record needs to be removed.Published as part of Skelley, Paul E., Clavijo-Bustos, Julian & Keller, Oliver, 2022, Extinct or extant?

SCARS: Suturing wounds due to conflicts between non-functional requirements in autonomous and robotic systems
No full textIn autonomous and robotic systems, the functional requirements (FRs) and non-functional requirements (NFRs) are gathered from multiple stakeholders. The different stakeholder requirements are associated with different components of the robotic system and with the contexts in which the system may operate. This aggregation of requirements from different sources (multiple stakeholders) often results in inconsistent or conflicting sets of requirements. Conflicts among NFRs for robotic systems heavily depend on features of actual execution contexts. It is essential to analyze the inconsistencies and conflicts among the requirements in the early planning phase to design the robotic systems in a systematic manner. In this work, we design and experimentally evaluate a framework, called SCARS, providing: (a) a domain-specific language extending the ROS2 Domain Specific Language (DSL) concepts by considering the different environmental contexts in which the system has to operate, (b) support to analyze their impact on NFRs, and (c) the computation of the optimal degree of NFR satisfaction that can be achieved within different system configurations. The effectiveness of SCARS has been validated on the iRobot (Formula presented.) Create (Formula presented.) 3 robot using Gazebo simulation
