↵* Arithmetic mean = sum of the percentages of innovations that assessed the criteria in each dimension divided by the total number of criteria in that dimension, e.g., for the dimension coverage: 54.2% = (45.8% + 58.3% + 25.0% + 87.5%) ÷ 4.
↵† The assessment data come from the teams’ responses to the Innovation Scalability Self-administered Questionnaire. (8)
