背景和上下文评估团队成员对软件开发项目的个人贡献是计算教师面临的一个关键问题。虽然教师通常依赖主观评估,但客观评估可以提供更有力的画面。为了探索这种可能性,在2020年的一篇论文中,Buffardi在高级软件工程项目课程中提出了客观指标和主观指标的相关分析(n= 41名学生和10个团队),发现只有两个显着的相关性。我们进行了一个更大规模的复制Buffardi研究(n= 118名学生和25个团队)在三个课程在三个institutions.MethodWe收集了相同的数据在Buffardi研究和计算相同的措施,从这些数据。我们复制了Buffardi的探索性,相关性和回归分析的客观和主观measurements.FindingsWhile复制Buffardi的五个显着的相关性研究结果中的四个,并部分复制Buffardi的回归分析的结果,我们的结果超越了Buffardi,通过确定八个额外的显着相关性。我们的大规模研究表明,在团队软件开发项目中,个人绩效的主观和客观度量可以有效地结合起来,以提供对个人绩效的一致和互补的评估。
Background and ContextAssessing team members’ indivdiual contributions to software development projects poses a key problem for computing instructors. While instructors typically rely on subjective assessments, objective assessments could provide a more robust picture. To explore this possibility, In a 2020 paper, Buffardi presented a correlational analysis of objective metrics and subjective metrics in an advanced software engineering project course (n= 41 students and 10 teams), finding only two significant correlations.ObjectiveTo explore the robustness of Buffardi’s findings and gain further insight, we conducted a larger scale replication of the Buffardi study (n= 118 students and 25 teams) in three courses at three institutions.MethodWe collected the same data as in the Buffardi study and computed the same measures from those data. We replicated Buffardi’s exploratory, correlational and regression analyses of objective and subjective measures.FindingsWhile replicating four of Buffardi’s five significant correlational findings and partially replicating the findings of Buffardi’s regression analyses, our results go beyond those of Buffardi by identifying eight additional significant correlations.ImplicationsIn contrast to Buffardi’s study, our larger scale study suggests that subjective and objective measures of individual performance in team software development projects can be fruitfully combined to provide consistent and complementary assessments of individual performance.
