Commentary. In this book I have focused on Benefit + Barrier which has a one-to-one mapping to the 3 S’s (Superior + Significant = Benefit and Sustainable = Barrier). However, in the field, the tripartite 3 S test of Power proves useful additionally because, since it calls out “Significant” separately, it makes materiality explicit. For example, businesses often tout network effects but, when looked at carefully, they are not material and therefore do not qualify as Power.
