PHASE 4: PSS DEVELOPMENT
Preparation (Phase 4 / Step 1) PSS Design (Phase 4 / Step 2) Elaboration of Results (Phase 4 / Step 3)

The PSS development phase starts from a well defined idea and brings the project to the detailed version necessary for its realisation. In order to describe a coherent and potentially successful PSS, the design activities will be strictly integrated with stakeholders’ involvement and user acceptance evaluation processes.
Objectives
The main objective of this phase is the detailed design of each PSS dimension (offering, system and interaction) and the elaboration of the specifications (specs) for the PSS implementation.
Involved
PSS development is a complex collaborative process coordinated by a project leader. Staff members are involved in different moments of the design process depending on the required competencies. This phase foresees the involvement of an enlarged project team made up of people with the required competencies for the PSS development and evaluation. The project team will be enlarged to include internal and external actors (advertising agency, interior design studio, web design agency, etc.) who will be in charge of implementing PSS components, such as representatives of stakeholders directly involved in the future PSS supply.
Main outputs
  • Classification of customers’needs.
  • Agreements with stakeholders.
  • Stakeholder System Map showing the precise system organisation for each PSS action.
  • Offering Diagram showing the PSS basic, added-value and sub-functionalities.
  • Detailed Interaction Table describing each PSS action in terms of interaction steps and PSS components.
  • Specifications (specs forms) for the implementation of the main PSS components.
