Industrial Product-Service Systems (PSS) are realized within the value creation network of the PSS-provider in close cooperation with customers. Thereby, the organizational and operational structure of the value creation network as well as the customer interaction itself must be designed in order to guarantee the PSS- provider continuous product and customer feedback. This feedback provides the basis for a continuous PSS-improvement process, comprising customer specific and customer spanning improvement measures. This paper analyzes demands on the value creation network structure in order to enable a PSS-provider to implement a continuous PSS-improvement process. Based thereon, a continuous PSS-improvement process is provided.
