B-Model Competition is slightly different than the B-Plan competition. It’s not just the presentation you give in the B-Plan competition. In a B-Model competition you need to have a prototype of your idea (if the idea is a tech related one which may include some hardware or app development). In case of a social entrepreneurial idea or one which includes large scale implementation or involvement of huge mechanism and tools or infrastructure etc. you may just come up with a feasible and relevant ground work.
