我们的研究重点是设计现代Web应用程序所需的工作。设计工作是整个开发工作的重要部分，因为实现可以通过工具实现部分自动化。
我们对工程和通信科学课程注册的大学高级班的学生进行了三项实证研究。实证研究基于W2000的使用，W2000是一种用于Web应用程序设计的专用设计符号，但假设和结果可能适用于更广泛类别的建模符号(例如，OOHDM、WebML或UWE)。我们首先调查了每项设计活动的相对重要性。然后，我们评估了先验设计工作预测的准确性，以及一些与过程相关的因素对每个设计活动所需工作的影响。我们还分析了W2000设计构件的大小和复杂性等属性对设计Web应用程序的用户体验所需的总工作量的影响。此外，通过研究这些属性中的哪些属性会影响使用W2000时所遵循的设计阶段的步骤，我们进行了更细粒度的分析。
Our research focuses on the effort needed for designing modern Web applications. The design effort is an important part of the total development effort, since the implementation can be partially automated by tools.
We carried out three empirical studies with students of advanced university classes enrolled in engineering and communication sciences curricula. The empirical studies are based on the use of W2000, a special-purpose design notation for the design of Web applications, but the hypotheses and results may apply to a wider class of modeling notations (e.g., OOHDM, WebML, or UWE). We started by investigating the relative importance of each design activity. We then assessed the accuracy of a priori design effort predictions and the influence of a few process-related factors on the effort needed for each design activity. We also analyzed the impact of attributes like the size and complexity of W2000 design artifacts on the total effort needed to design the user experience of web applications. In addition, we carried out a finer-grain analysis, by studying which of these attributes impact the effort devoted to the steps of the design phase that are followed when using W2000.
