在本文中，我们报告了对工程设计过程的深入研究。具体来说，我们扩展了之前对工程学生设计过程的研究，以比较学生和专家工程师的设计行为。来自不同工程学科和行业的 19 名专家各自在实验室环境中设计了一个游乐场，并在设计任务期间口头报告了他们的想法。他们的设计流程和解决方案质量的衡量标准与 26 名新生和 24 名大四学生的现有数据进行了比较。总体而言，专家们在这项任务上花费了更多的时间。在工程设计的每个阶段，包括更多的时间来确定问题范围。专家们还收集了更多涵盖更多类别的信息。结果支持这样的论点：问题范围界定和信息收集是高级工程师和学生之间的主要区别，也是工程专业学生需要培养的重要能力。专家设计师流程的时间线展示说明了我们发现的特征差异，并可以帮助学生深入了解自己的设计流程。
In this paper we report on an in-depth study of engineering design processes. Specifically, we extend our previous research on engineering student design processes to compare the design behavior of students and expert engineers. Nineteen experts from a variety of engineering disciplines and industries each designed a playground in a lab setting, and gave verbal reports of their thoughts during the design task. Measures of their design processes and solution quality were compared to pre-existing data from 26 freshmen and 24 seniors. The experts spent significantly more time on the task overall. and in each stage of engineering design, including significantly more time problem scoping. The experts also gathered significantly more information covering more categories. Results support the argument that problem scoping and information gathering are major differences between advanced engineers and students, and important competencies for engineering students to develop. Timeline representations of the expert designers' processes illustrate characteristic distinctions we found and may help students gain insights into their own design processes.
