QUESt: new practices to represent hypotheses in experiment-driven software development

Ambiguity in user stories: A systematic literature review

“…Studies focusing on detecting ambiguity generally applied means of automatic interpretation of natural language requirements (e.g., [24,28,37,[39][40][41]) or the transformation of natural language requirements into models (e. g., [36,[42][43][44][45][46][47]). Studies that aimed to reduce ambiguity in natural language requirements proposed grammatical restrictions (e.g., [26,[48][49][50]), the standardization of sentence structures (e.g., [32,51,52]), and models or ontologies supporting requirements formulation (e.g., [53][54][55][56][57]).…”

“…Ambiguity can also lead to a user story being incomplete regarding the description of a feature that a user expects from a system. Several studies have mentioned neglected requirements [52,56], while team member turnover has been identified as a cause [26,78]. Insufficiency as a semantic ambiguity problem has been demonstrated by reviewing a user story in the context of previously written user stories [26,56,78].…”

“…Finally, studies focusing more on insufficiency as pragmatic ambiguity have investigated how technical users can be supported in understanding user stories more sufficiently [52].…”

“…The use of Personas as a technique to improve the understandability of user stories was proposed in [32]. As a result of an experimental study, a writing guideline for user stories was presented in [52]. We classify both solutions as frameworks.…”

Informatização do processo de seleção de bolsistas de assistência estudantil: a experiência do IFMG

“…Situações que demandavam compreensão de fluxos de trabalho foram modeladas graficamente com o apoio do Diagrama de Transição de Estados da UML (Unified Modeling Language). A partir do conhecimento gerado nessas reuniões, a equipe do projeto realizou a compreensão e o refinamento dos requisitos do sistema, fazendo sua documentação no formato de Estórias de Usuário (Melegati & Wang, 2019). Na sequência, o modelo físico dos dados foi elaborado para que houvesse uma visão mais compreensiva da estrutura necessária ao armazenamento dos dados do sistema.…”
