The average scores are clustered in the middle, mainly between scores of 3 and 4 for both impact and feasibility of implementation. This is a common observation made in STREAM workshops, as there is a tendency among participants to score technologies that they may be less familiar with in the 'middle'. This may also be linked to the broad range of the technology clusters – i.e. some technologies within the clusters may be individually scored higher than others, but combined they receive a 'middle' average score.
