Besides, an analytical analysis based on GOMS (Goals, Operators, Methods and Selection Rules) complements the previous experiment.Įxample Class diagram used in the empirical evaluation The main one is an empirical experiment supported by more than 12 hours of screen recordings (interaction with the modeling tools including verbal audio comments) registered by undergraduate students during the construction of a UML class diagram. To answer these research questions, we carried out two studies employing different research approaches. ![]() ![]() In both cases, obstacles have been analyzed and classified under the CRUD (Create, Read, Update and Delete) perspective, that is, the obstacles are contextualized according to whether they have arisen when the elements of the diagram are Created (C), Read (R), Updated (U) or Deleted (D). RQ3: What are the most common obstacles (difficulties and errors) encountered by modelers when modeling UML class diagrams? This last RQ is centered on the difficulties participants encountered with the use of modeling tools as well as the mistakes made by the modelers while using these tools. ![]() the complete effort devoted to modeling the whole class diagram, including the effort devoted to initialization tasks. the work devoted to initialize the modeling tool and create an empty class diagram and
