With predefined metrics this tool allows for fast evaluation of one PSS concept compared to another. The tool is intended to be used by each team member, individually, ensuring that the full team has the possibility to give its input to the PSS conceptualisation process, to identify discrepancies and facilitate the discussion. The tool supports both the changing and adding of new criteria to suit the application.

See Workbook 4 for a more  thorough description of the tool and how to use it.
