If an innovation doesn’t appear to be replicable, is it still eligible for a nomination?
Yes. As an example, Professor Mauricio Cardenas from Unversidad de Los Andes, Colombia, students identified several interesting candidates, however none of them would be replicable. They are highly local, depending on the local conditions, context, government, etc. This is not a limitation to submitting them.
Another member, Professor Kerul Kassel from Fielding University, USA, suggested that replicability may be considered something like "What patterns does this story present that could be of value in other contexts?"
