“…The GQM template for goal definition [12,13] was used to define the goal of our experiment as follows: "Analyze the level of detail in UML models with the purpose of evaluating it with respect to the maintainability of source code from the point of view of researchers, in the context of Computer Science students at the University of Leiden. As in [3], we considered that the LoD in UML models should be defined as the amount of information that is used to represent a modeling element. LoD is a 'continuous' metric, but for the experiment we have taken two "extremes" -high and low LoD.…”

“…The current increasing complexity of software projects [1] has led to the emergence of UML [2] as a tool with which to increase the understanding between customer and developer and to improve communication among team members [3]. Despite this, not all UML diagrams have the same complexity, layout, level of abstraction, etc.…”

Abstract. This paper presents an experiment carried out as a pilot study to obtain a first insight into the influence of the quality of UML models on the maintenance of the corresponding source code. The quality of the UML models is assessed by studying the amount of information they contain as measured through a level of detail metric. The experiment was carried out with 11 Computer Science students from the University of Leiden. The results obtained indicate a slight tendency towards obtaining better results when using low level of detail UML models, which contradicts our expectations based on previous research found in literature. Nevertheless, we are conscious that the results should be considered as preliminary results given the low number of subjects that participated in the experiment. Further replications of this experiment are planned with students and professionals in order to obtain more conclusive results.

“…It first appeared in 1997 and has now become one of the most widely-used modeling languages in industry. There is empirical evidence of its benefits during software development because it increases the understanding between customer and developer and improves communication among team members [6]. UML also improves the source code quality by reducing its defect density [7].…”

Context: Although various success stories of model-based approaches are reported in literature, there is still a significant resistance to model-based development in many software organizations because the UML is perceived to be expensive and not necessarily cost-effective. It is also important to gather empirical evidence in which context and under which conditions the UML makes or does not make a practical difference. Objective: Our objective is to provide empirical evidence as to which UML diagrams are more helpful during software maintenance: Forward Designed (FD) UML diagrams or Reverse Engineered (RE) UML diagrams. Method: We carried out a family of experiments which consisted of one experiment and two replications with a total of 169 Computer Science undergraduate students. Results: The individual data analysis and the meta-analysis conducted on the whole family, show a tendency in favor of FD diagrams and are significantly different as regards the effectiveness and efficiency of the subjects who participated and played the role of maintainers. The analysis of the qualitative data, collected using a post-experiment survey, reveals that the subjects did not consider RE diagrams helpful. Conclusions: Our findings show that there are some objective results (descriptive statistics or statistical tests) related to the maintenance effectiveness and efficiency in favor of the use of FD UML diagrams during software maintenance. Subjective opinions also lead us to recommend the use of UML diagrams (especially class diagrams) created during the design phase for software maintenance because they improve the understanding of the system in comparison with RE diagrams. Nevertheless, we can only assume that these results are valid in the context of Computer Science undergraduate students when working with small systems related to well-known domains, and other contexts should be explored in order to reaffirm the results in an industrial context by carrying out replications with professionals.
