“…We also plan to analyse the use of additional inter-dependencies as discussed in [Aydemir et al 2018], in order to provide even more information for the viewers of the models. Lastly, we plan to expand the visualization strategies beyond the scope of requirements prioritization and release planning -e.g., for tracking software development in terms of elements to do/doing/done.…”

“…Aydemir et al [Aydemir et al 2018] propose a goal-based approach for addressing the next release problem -that is, selecting which requirements to implement next, from a set of candidate requirements. They extend traditional goal trees with a set of inter-dependency constraints, such as REQUIRES (R1 requires R2 to function) and TEMPORAL (R1 needs to be implemented before R2).…”

Attributes such as cost, risk, priority, and customer satisfaction are integral components of requirements specifications, helping with decision-making during the software development process. Moreover, requirements status and stability are relevant meta-information for requirements management. Even though goal modelling is a visual approach for requirements engineering that enables expressing and reasoning about goals, qualities, tasks and resources, existing approaches do not include the aforementioned attributes as part of the visualization of the models. This paper presents a set of strategies for visually representing requirements attributes over goal models, aiming at minimizing the cognitive effort required in their analysis. The proposal is supported by a tool that implements the visualization strategies here defined. Empirical evaluation of the effectiveness of the proposal, however, is expected to be carried out as future work.

“…Since this first approach is based on the problem statement in [12], it is assumed that all features are independent from each other, which is an unrealistic assumption. One possible improvement would be to combine the feature specifications with goal models, as done by Aydemir et al [27], and in this way also consider dependencies between features and requirements when searching for optimal release candidates.…”

Smart Cities are developing in parallel with the global trend towards urbanization. The ultimate goal of Smart City projects is to deliver a positive impact for the citizens and the socio-economic and ecological environment. This involves the challenge to derive concrete requirements for (technical) projects from overarching concepts like Quality of Life (QoL) and Subjective Well-Being (SWB). Linking long-term, impact oriented goals with project outputs and outcomes is a complex problem. Decision making on requirements and resulting features of single Smart City projects (or systems) is even more complex since cities are not like monolithic, hierarchical and wellstructured systems. Nevertheless, systems engineering provides concepts which support decision making in such situations. Complex socio-technical systems such as smart cities can be characterized as systems of systems (SoS). A SoS is composed of independently developed systems that nevertheless provide a higher-level integrated functionality. To add new functionality to a SoS, either existing systems must be extended or new systems must be developed and integrated. In both cases, the extension of functionality is usually done in small increments and structured via software releases. However, the decision which features to include in the next release is complex and difficult to manage when done manually. To address this, we make use of the multiobjective next release problem (MONRP) to search for an optimal set of features for a software release in a SoS context. In order to refine the search in an early planning phase, we propose a technique to model and validate the features using the scenario modeling language for Kotlin (SMLK). This is demonstrated with a proof-of-concept implementation.

“…Li et al develop a decision support framework METRO for the Next Release Problem to manage algorithmic uncertainty and requirements uncertainty [18]. Aydemir et al frame the Next Release Problem in terms of constrained goal models [19]. Although these papers are effective for decision making, they do not fully consider the perspective of fairness.…”

Fairness Analysis in Goal-Oriented Requirements Selection

Requirements analysis is an important step in business information system development. Goal-oriented requirements analysis is a powerful method that captures requirements to be satisfied in business information systems as goals and derives means for achieving goals or alternative means. The difficulty in this analysis is that it is difficult to analyze manually when the combination of goals is huge, and to take into account the preferences of the various stakeholders. It is difficult to satisfy the requirements of all stakeholders at the same time because preferences are different and trade-offs for each stakeholder. Therefore, there is a risk that the requirements of some stakeholders may be ignored. Therefore, in this paper, we propose a method using multi-objective optimization to take into account stakeholder preference and to make goal selection with emphasis on fairness. Our method performs a goal selection having both high utility and fairness of the entire stakeholders. We evaluated by a case study and showed the effectiveness.
