Humankind faces many “wicked” decision-making problems, which must be solved. One promising approach refers to crowdsourcing systems that hold the potential to solve any kind of problem – notably wicked ones. Crowdsourced solutions work well because crowds exchange knowledge from different domains – a concept known as “cross-fertilisation.” Thereby, the “facilitator” of a crowdsourcing system is the primary decision maker when it comes to specifying and managing the crowd. The facilitator's role includes actively managing cross-fertilisation. However, in the light of technological advancements and large-scale data, facilitation proves difficult – especially in one particular type of crowdsourcing – crowdsolving. Thus, academia recently called for relieving some burden of facilitators and started developing tools for supporting or automated facilitation. Yet, the focus of existing tools is not on fostering the innermost core of crowdsolving endeavours – cross-fertilisation. By taking a design science perspective, we propose design principles and design guidelines for a decision-support tool aiding facilitators to (a) set the boundary conditions for, (b) measure, and (c) facilitate cross-fertilisation. We evaluate feasibility and value added of the abstract design by applying it to different crowdsolving platforms including a prototypical implementation and qualitative evaluation by facilitators.

人类面临许多“邪恶”的决策问题，必须解决。一种有前途的方法是指具有解决任何类型问题（尤其是邪恶问题）的潜力的众包系统。众包解决方案之所以有效，是因为众包可以交流来自不同领域的知识，这一概念被称为“跨性别”。因此，在指定和管理人群时，众包系统的“促进者”是主要的决策者。主持人的角色包括积极管理交叉受精。但是，鉴于技术进步和大规模数据，便利化被证明是困难的，尤其是在一种特定类型的众包中。从而，学术界最近呼吁减轻协调人的负担，并开始开发支持或自动协调的工具。但是，现有工具的重点不是培养群众解决方案的最核心部分-交叉施肥。从设计科学的角度出发，我们为决策支持工具提出了设计原则和设计指南，以帮助协调人（a）设置边界条件，（b）措施和（c）促进交叉受精。我们通过将抽象设计应用于不同的众筹平台，包括原型实施和主持人的定性评估，来评估抽象设计的可行性和附加值。从设计科学的角度出发，我们为决策支持工具提出了设计原则和设计指南，以帮助协调人（a）设置边界条件，（b）措施和（c）促进交叉受精。我们通过将抽象设计应用于不同的众筹平台，包括原型实施和主持人的定性评估，来评估抽象设计的可行性和附加值。从设计科学的角度出发，我们为决策支持工具提出了设计原则和设计指南，以帮助协调人（a）设置边界条件，（b）措施和（c）促进交叉受精。我们通过将抽象设计应用于不同的众筹平台，包括原型实施和主持人的定性评估，来评估抽象设计的可行性和附加值。
