    Smart Services can be described as a specific manifestation of Product-Service Systems, which mainly refer to customer individual solutions based on the utilization of data derived from cyber-physical products and production systems. In this context the usage data is allocated and analyzed on a platform in order to extract valuable information, thus enabling the development and operationalization of new data-driven business models. In order to support the initial design of Smart Services companies have to achieve a thorough understanding of their existing or obtainable data as well as the related potential options to utilize these data. Based on the analysis of 51 industrial Smart Service use cases data flows and areas of application have been derived and clustered. Moreover, the defined categories are interlinked and mapped to the use cases. The findings have been comprised into an applicable Smart Service design method addressing early design stages. Finally, the approach (DAU flow method) has been applied and evaluated with two case companies, indicating sound qualitative results and providing valuable feedback.

    The ongoing discussion about digital transformation in combination with new digital services is increasing uncertainties in companies on how to proceed regarding their strategic development of new products, services as well as integrated offers. The main challenges for companies has been stated in several industrial workshops and projects. They comprise the assessment of the current situation, identifying the business value of digital transformation as well as the necessary capabilities needed regarding the implementation of a target vision. Based on the results of a literature analysis as well as initial prescriptive and descriptive study a revised PSS maturity model has been developed for assessing the status of a company reflecting on four dimensions: value proposition, business processes, customer and sustainability. The approach is complemented with an online self-assessment tool and generic action recommendations. The methodology has been applied and evaluated with a case company. The qualitative results indicate a good user acceptance and a very good ease of use as well as an improvable feedback regarding the action recommendations.

    Product-Service Systems (PSS) enhance product-centered offers with services and infrastructure in order to provide customer-oriented solutions. These new concepts enable companies to innovate their portfolio, thus supporting creative and adaptable solutions [1]. One of the major challenges is the integrated development of both tangible products and intangible services in respect to their interdependencies. For this reason researchers proposed a versatile set of methods and tools regarding the development of PSS. Nevertheless, two discrepancies can be stated: Firstly, prototyping has been studied inadequately in PSS research so far. For this reason Exner et al. proposed new approaches to fill this gap [2], including remarks to further proceed research with different degrees of technological utilization. Secondly, although customer-orientation and customer integration has been recognized as crucial for PSS, the involvement of clients or consumers in the design process is often disregarded. Consequently, this paper presents an extensive literature research regarding active customer integration and prototyping in PSS design processes. Based on these insights a concept for a new PSS prototyping approach is introduced. The method focuses on PSS concept development including the integration of the customer to evaluate and develop the concepts with intuitive touch technologies.
