Note: The higher a technology is scored on the criteria, the greater the expect impact and feasibility of implementation. For impact criteria, the scale ranges from 1 (negative impact – reduction in capability compared to current practices) to 5 (ground-breaking impact – paradigm shift in capability compared to current practices). For feasibility of implementation criteria, the scale ranges from 1 (insurmountable barriers – barriers could not be overcome) to 5 (negligible or no concern about barrier – barrier could be overcome with very minor or no change or disruption). See Annex B for a full description of the STREAM scores and criteria.
