“…Henceforth, we conducted several industrial and academic investigations devoted to service prototyping and realized service prototypes. In previous studies, we have covered the service innovation aspect of service prototyping [7,10] and service prototyping framework and model that were used to design this experiment [8]. As well as the experience feedback of industrial stakeholders from a workshop dedicated to explore SP forms [9].…”

Immersive technologies, such as: Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR), in service prototyping have the potential to enhancing the co-creation of service ideas. It is intended to transform intangible service aspects into an experience, even before the service exists. However, there is a lack of research studies comparing different forms of service prototype. Such studies would help to find out the most appropriate Service Prototype (SP) form for exploring, communicating and evaluating new service ideas. Several SP experiment sessions were conducted in France and Germany within an academic context in 2018 to compare different performance factors of conventional Service Prototypes (CSP) versus Immersive Service Prototypes (ISP). The participants have to disassemble and then reassemble a simple three-part mechanical element with the aid of four different SP forms. This paper presents the results of the experiment sessions, involving 38 participants, conducted at Furtwangen University campus in Germany. These results reveal that participants preferred ISP forms rather than CSP forms. However, it also confirms that there are still some difficulties in applying and using VR or AR devices.

“…ISP was also intended to evaluate human behavior through user experience, and simulated service environments. The mentioned papers in the table 2 mostly discussed the optimization of: (1) service processes (Exner et al, 2014;Arvola et al, 2012;Fukuhara et al, 2014); (2) the improvement of service designs (Kwon et al, 2015;Peng et al, 2017); (3) service training processes (Jung Bae and Seong Leem, 2014;Boletsis et al, 2017); (4) service prototyping methods Kuure et al, 2014). We identified one case that applied quantitative method to evaluate the appropriateness of a 3D VR service App that engaged 30 participants (Peng et al, 2017).…”

For years, Immersive Technologies and 3D printing, demonstrated their capacity to quickly build product prototypes in order to reach a common understanding among all stakeholders, especially potential users. Service prototyping is a novel agile process intended to accelerate the service development, while improving the overall anticipated service experience. The use of Immersive Technologies in service prototyping is intended to enable a co-creative and explorative service experience, even before the service really exists. Service prototyping transforms intangible processes into a real experience. Immersive Technologies are already deployed in several industrial applications ranging from product design to product and service exploration. They are also used for conducting training even before the product or service exists. The main concern remains in the fact that there is a lack of study for comparing and selecting the most appropriate form of Service Prototypes (SP) to explore a new service. This paper presents our empirical study comparing different SP forms and the results of two experiment sessions that were conducted at ENSAM Laval and Angers campuses. These results reveal that participants preferred immersive forms rather than conventional forms. However, it also unveils some difficulties in properly handling Immersive Technologies.

“…It should be tested, if the intended use of resources as well as the design of the system for planned compliance with its requirements is sufficient [7]. In the area of services a pilot phase is often initiated in which the proposed system is tested with all its components in an idealized environment.…”

Product-service systems (PSS) can improve sustainability in terms of responsibility of providers and intensified customer-provider relationships. Therefore, a PSS approach has been applied on the distribution of solar home systems in rural areas of emerging countries to improve quality and increase confidence in this technology. However, many innovative projects fail at the piloting stage because of insufficient validation before implementation. Validation methods for PSS like an integrated gap model (e.g. identification of gaps between deliverables and customers expectations) or interdisciplinary design reviews show its limits on the interdependences between product and service development. A new approach to test PSS involves agent-based simulation models and is presented within this paper. Among system dynamics and discrete event simulation, an agent-based simulation is able to work with less quantitative data and a more detailed view on individual entities than the alternative approaches. Thus, it is possible to create more realistic simulation models to validate especially resource planning of a PSS. Agent-based simulation is used within the MEVIS (Micro Energy Supply Information System) project to model a network of solar home systems which are controlled by remote monitoring in order to improve service processes, e. g. maintenance and repair operations. The pilot test should be carried out efficiently by the preceding virtual validation in the form of a simulation, which is built in NetLogo, a tool that enables modeling of a multi-agent environment. Within this environment, communicating technical artifacts as well as different groups of actors are mapped as agents. As a result, diagrams of relevant parameters like the overall repair costs or the estimated customer's satisfaction are displayed and the resource planning is visually supported. This helps to push a PSS into a new market, where you have to deal with existing resources that must be used efficiently. The contributions in this paper provide the conception and an exemplary presentation of the simulation run.
