Product/Service-Systems (PSS) strategies can be observed as part of an overall movement towards a service-based society that is increasingly knowledge and information based, and where sustainability is in focus. PSS deals are contracted on the characteristic to provide ‘functions per unit’. The ownership of the physical product may remains with the manufacturer or a joint venture, a venture that will operate in a cross-company situation with a multitude of knowledge workers.Knowledge sharing for cross-company innovation projects has been recognised as troublesome, since disparate knowledge domains must be brought together in a cohesive way to support creativity and also innovations. This paper describes an approach to lightweight knowledge sharing for the purpose of supporting cross-functional design. This ‘Engineering 2.0’ approach makes it possible to link, with low overhead effort, customer needs, support issues etc directly to the development teams responsible for developing solutions to the identified issues.
