Title: Prototyping tools for validation of PSS offerings: augmented and virtual reality tools
Abstract: The development of a Product-Service System (PSS) to fulfill customer needs through innovative and sustainable business models that integrate products, services, networks of actors, and supporting infrastructure is seen as the way to grow competitiveness and obtain better economic and environmental results.
The PSS validation is one of the major challenges during product and service development and can ensure the effectiveness of integrated solution. One way to validate whether the requirements defined for the solution meet the expectations and needs of customers, from the early stages of the development process, is through prototyping. The use of prototypes can enable the integration of the customer in the development process and provide the opportunity to test the solution front the early stages, identify points of failure and improving opportunities and reproduce the solution allowing that PSS value could be evaluated.
Prototyping PSS offerings often requires the use of high-fidelity techniques or a mixture of techniques from both perspectives: low (e.g., paper sketches, cardboard mockup) and high-fidelity (physical and virtual mock-up, software, virtual simulation). The low fidelity of traditional techniques can be limited to validating aspects of experience and services contained in various PSS offerings.
The use of technologies, such as Virtual Reality (VR) and Augmented Reality (AR), are being studied for developing High-Fidelity prototypes in the PSS development process, focus on the tangible product part. However, the use of VR and AR for prototyping Product-Service System in a holistic view, considering different PSS business models, has not been widely reported in the literature. Moreover, it is noticed that there is a gap in the literature about which prototyping tools are more appropriate depending on the type of PSS offering (product-oriented, or result-oriented or oriented) and how to validate the sustainable aspects of the PSS offerings.
In conclusion, existing different prototyping tools that are not easily adapted to validate PSS offerings due to the complexity and interdependencies between PSS features. New approaches are needed to focus on the tangible product part but also on the evaluation of service activities in an integrated way.
