Product-Service Systems (PSS) have been justified by a desire to find sustainable solutions that go beyond contemporary approaches. The characteristics of PSS of-ferings are to link goods and services in development and to provide systemic per-formance-based solutions to the customers. This paper investigates how estab-lished strategic product development tools for socio-ecological sustainability could be adapted for PSS development. An approach is suggested for how to apply these tools in early PSS development phases.
