Designers play an important role in service transformation and the development of product-service systems by applying co-creation methods. This paper presents a case of how we applied co-creation in practice and the impact this has had on developing a circular product-service system. It details the method used in the co-creation process and highlights five benefits, such as the ability to develop value-adding services for repairs and supporting each of them with user citations. Furthermore, we interviewed the project team a year into product development to assess the uptake by the company and the impact co-creation had on their design process. Based on these findings, we present a conceptual model that identifies the tangible impacts of co-creation and visualizes at what stages and levels co-creation can impact both the development of product-service systems and a company’s shift along the servitization continuum.

设计师通过应用联合创建方法在服务转换和产品服务系统开发中扮演重要角色。本文介绍了一个案例，说明了我们如何在实践中应用共创以及对开发循环产品服务系统产生的影响。它详细介绍了在联合创建过程中使用的方法，并着重强调了五个好处，例如能够开发用于维修的增值服务，并通过用户引用为每一项提供支持。此外，我们在产品开发方面与项目团队进行了一年的访谈，以评估公司的采用情况以及共同创造对其设计过程的影响。根据这些发现，
