本文考虑了分布在多个设计方的三种不同的设计工作模式：独立设计（并行，无设计交互，子系统需求），依赖设计（顺序，单向设计交互，更新子系统需求）和相互依赖设计（并行或顺序，双向设计交互，仅系统需求）。系统和子系统需求都表示为所谓的解决方案空间。解决方案空间表示允许的设计集，其中可以从系统解决方案空间推导出子系统（或组件）解决方案空间。子系统解决方案空间的规模越大，满足整体系统需求的子系统设计决策的选择就越多，设计灵活性也就越大。这三种模式应用于两个工业设计问题，并根据与迭代步骤、设计方之间的交互和需求制定相关的总体灵活性和成本进行评估。由此产生的框架适用于一般系统设计问题。
This paper considers three different modes of design work that is distributed over several design parties: independent design (in parallel, no design interactions, sub-system requirements), dependent design (sequential, one-way design interactions, updated sub-system requirements) and interdependent design (in parallel or sequential, two-way design interactions, only system requirements). Both system and sub-system requirements are expressed as so-called solution spaces. Solution spaces represent sets of permissible designs where sub-system (or component) solution spaces can be deduced from the system solution space. The larger the size of a sub-system solution space, the more options for sub-system design decisions satisfying the overall system requirements exist and thus the larger the design flexibility. The three modes are applied to two industrial design problems and evaluated with respect to total flexibility and cost related to iteration steps, interactions between the design parties and requirement formulation. The resulting framework is applicable to general systems design problems.
