This toolkit is an ongoing effort to develop a methodology, with tools and techniques, to design meaningful product-service systems. It mixes state-of-the-art insights of the domains of systems thinking, service design, human-centered design, interaction design, product design and design thinking. Furthermore, the toolkit can also be used to solve complex societal challenges and Internet of Things connected issues. Its tools and techniques alternate between whole and particle thinking and helps the reader to zoom in and out. The reader receives an iterative support with the aim to explore and exploit, a foundation to build new product-service systems that concentrate on the delivery of value to the customer with a focus on the integration of product and service.
