Supporting Decision Making in Value-Oriented Design: A Multidomain System Value Model
本文提出了一个通用的多领域系统价值模型，作为决策支持工具，帮助设计者系统分析系统价值、评估备选方案，并揭示不同态度，从而提升设计结果的价值。
The main goal of design is to create value. Recently, there has been a growing understanding that value extends beyond purely economic and technical factors and should embrace the multifaceted sociotechnical ecosystem. Studies discussing system value acknowledge its imperative role in design while observing the lack of a comprehensive value notion complying with the need. In this article, the primary objective is to propose a holistic multidomain system value model (SVM), targeted to be general and field agnostic, to be utilized as a decision-support tool. The generation of the model includes the synthesis of multiple, transcending engineering, data sources, system value ontology formulation, and design of a concise SVM. Aiming to be practical and generally applicable, the SVM is validated by focus groups and case studies, analyzing engineered systems along with policy-related decisions. The findings indicate that the suggested model enables systematic and time-efficient system value analysis, assisting in evaluating alternatives and unveiling differing attitudes. Used as a decision-making support tool, the SVM can transform the scope of discussions, expand the range of factors considered during alternatives comparison, and guide the way toward higher value outcomes.
