我们对Porter-Votta-Basili实验进行了扩展复制，比较了场景方法和使用相同仪器检查需求规格的清单方法。与原始缺陷列表相比，该实验是在我们的教育环境中进行的，其缺陷的定义更一般。我们涉及24名本科生的研究操纵了三个自变量：检测方法，需求规范和检查顺序。所测量的因变量是缺陷检测率。我们发现检查的需求规范检查，而不是检测方法是缺陷检测率方差的最可能的解释。这表明，重要的是要了解需求规范如何传达对产品的可理解观点并相应地调整检查方法的知识。与原始实验相反，我们无法显着支持场景方法的优越性。这与Fusaro，Lanubile和Visaggio进行的复制相符，并且可以通过缺乏我们经验不足的受试者的个人缺陷检测技能来解释。
We have performed an extended replication of the Porter-Votta-Basili experiment comparing the Scenario method and the Checklist method for inspecting requirements specifications using identical instruments. The experiment has been conducted in our educational context represented by a more general definition of a defect compared to the original defect list. Our study involving 24 undergraduate students manipulated three independent variables: detection method, requirements specification, and the order of the inspections. The dependent variable measured is the defect detection rate. We found the requirements specification inspected and not the detection method to be the most probable explanation for the variance in defect detection rate. This suggests that it is important to gather knowledge of how a requirements specification can convey an understandable view of the product and to adapt inspection methods accordingly. Contrary to the original experiment, we can not significantly support the superiority of the Scenario method. This is in accordance with a replication conducted by Fusaro, Lanubile and Visaggio, and might be explained by the lack of individual defect detection skill of our less experienced subjects.
