Despite the growing research interest in PSS design and development methods in recent years, there is still no fully stabilized and shared understanding of the PSS design process. This can be partly explained by two main gaps: the decoupled design of product and services and the lack of operational solutions. This research aims at outlining the main characteristics of a proposal for a new PSS design framework, expected to contribute answering these 2 gaps. The proposition is based jointly on a recently created PSS design methodology and an extension of the functional analysis (FA) approach (NF X 50-100), which is commonly used in product design. The proposed framework intends to smoothly integrate the whole PSS design process, including product-service design and the network configuration.
