Decision-making is a core engineering design activity that conveys the engineer's knowledge and translates it into courses of action. Capturing this form of knowledge can reap potential benefits for the engineering teams and enhance development efficiency. Despite its clear value, traditional decision capture often requires a significant amount of effort and still falls short of capturing the necessary context for reuse. Model-based systems engineering (MBSE) can be a promising solution to address these challenges by embedding decisions directly within system models, which can reduce the capture workload while maintaining explicit links to requirements, behaviors, and architectural elements. This article discusses a lightweight framework for integrating decision capture into MBSE workflows by representing decision alternatives as system model slices. Using a simplified industry example from aircraft architecture, we discuss the main challenges associated with decision capture and propose preliminary solutions to address these challenges.

翻译：决策是工程设计中的核心活动，它传递工程师的知识并将其转化为行动方案。捕获这种形式的知识能为工程团队带来潜在收益，并提升开发效率。尽管其价值显而易见，传统的决策捕获通常需要大量投入，且仍难以捕获可复用所需的必要上下文。基于模型的系统工程（MBSE）通过将决策直接嵌入系统模型中，为解决这些挑战提供了前景广阔的解决方案——这既能减少捕获工作量，又能保持与需求、行为及架构要素的显式关联。本文讨论了一种将决策捕获集成到MBSE工作流的轻量级框架，该框架通过将决策备选方案表示为系统模型切片来实现。借助一个简化的飞机架构行业案例，我们探讨了与决策捕获相关的主要挑战，并提出了应对这些挑战的初步解决方案。
