Elaboração e avaliação de um catálogo de requisitos não-funcionais em um contexto de domínio de aplicação de diplomas digitais

Abstract

The adoption of the Digital Diploma in Brazil has created a context in which issuance and registration systems must comply with particularly rigorous quality standards. However, there is a lack of a systematized and structured definition of non-functional requirements (NFRs) for this domain, which hinders consistent specification and compromises well-founded architectural decision-making. This work addresses this gap by proposing a systematized catalog of NFRs for the Digital Diploma domain, motivated by the need to guide the development of more robust solutions aligned with regulatory requirements. The objective of this research was to design, model, and validate a catalog based on the NFR Framework, represented through Softgoal Interdependency Graphs(SIGs).Themethodologycombinedlegislativeanalysis,anobservational study of a real-world system, a Systematic Literature Review, application of the ATAM method, SIG modeling, expert validation through a survey, and a Proof of Concept to assess practical applicability. The results indicate that the catalog is comprehensive, technically consistent, and considered useful by specialists, while also demonstrating applicability in real-world scenarios. The proposed operationalizations showed potential to support architectural decision-making and inspire functionalities in other systems. Thus, this work delivers an updated and applicable artifact that contributes to the development of more secure and interoperable Digital Diploma systems.
