20.500.12556/RUL-116723 Impact of the conceptual model's representation format on identifying and understanding user stories Context: Eliciting user stories is a major challenge for agile development approaches. Conceptual models are used to support the identification of user stories and increase their understanding. In many companies, existing model documentation stored as either use cases or BPMN models is available. However, these two types of business process models might not be equally effective for elicitation tasks due to their formats. Objective: We address the effectiveness of different elicitation tasks when supported either with visual or textual conceptual model. Since the agile literature shows little attention to reusing existing BPMN documentation, we propose several hypotheses to compare it to the use of textual use case models. Method: We conducted an experiment to compare the effectiveness of the two business process formats: textual use cases and visual BPMN models. We studied their effects on three elicitation tasks: identifying user stories and understanding their execution-order and integration dependencies. Results: The subjects better understood execution-order dependencies when visual input in the form of BPMN models was provided. The performance of the other two tasks showed no statistical differences. Conclusion: We addressed an important problem of user story elicitation: which informationally equivalent model (visual BPMN or textual use case) is more effective when identifying and understanding user stories. informatics business process models poslovni proces modeli informatika poslovni proces modeli true false false Angleški jezik Slovenski jezik Članek v reviji 2020-06-05 12:57:06 2020-06-05 13:00:21 2022-08-29 03:38:45 0000-00-00 00:00:00 2019 0 0 art. 106168 Vol. 116 Dec. 2019 0000-00-00 PostprintKoncna NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2021-08-03 659.2:004 0950-5849 10.1016/j.infsof.2019.08.001 25212646 25611520 RAZ_Trkman_Marina_2019.pdf RAZ_Trkman_Marina_2019.pdf 1 8D198A526371A51E72F5AA61A6DE0CBA 150be8019f2a310b4dbf4258d141d0550ed4bd976cb196ff60e7837f401853e0 ff34726d-a1b8-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=130393 https://www.sciencedirect.com/science/article/abs/pii/S095058491930165X?via%3Dihub 0 d1cb23bd-a7fd-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142560 Ekonomska fakulteta 0 0 0
