Pahl和Beitz的“系统方法”通常被视为基于专业设计实践观察的设计规范模型。在本文中，我们将研究这个模型是否可以作为一个预测模型。这是通过测试其预测能力的学生，正式教授设计和设计方法的设计行为。在这项研究中使用的行为观察是基于15个设计会议的协议，涉及机械工程专业的学生后，他们的第一年的设计教育和31个设计会议的学生使用各种概念生成方法。设计协议和系统方法统一使用功能-行为-结构（FBS）设计问题模式进行编码。累积发生分析是用来获得定性和定量的措施，作为系统方法的预测和学生的设计行为之间的比较的基础。结果表明，系统方法可以预测部分，但不是所有的学生的设计问题行为。
Pahl and Beitz’ ‘Systematic Approach’ is generally seen as a prescriptive model of designing based on observations of professional design practice. In this paper, we examine whether this model can be used as a predictive model. This is done by testing its predictive capacity for the design behaviour of students that are formally taught design and design methods. The behavioural observations used in this study are based on protocols of 15 design sessions involving mechanical engineering students after their first year of design education and 31 design sessions of the students using various concept generation methods. The design protocols and the Systematic Approach are coded uniformly using the Function–Behaviour–Structure (FBS) design issue schema. Cumulative occurrence analysis is used to derive qualitative and quantitative measures as a basis for comparison between the Systematic Approach’s prediction and the students’ design behaviour. The results indicate that the Systematic Approach can predict some but not all of students’ design issue behaviour.
