2. The standardized high-attrition funnel

Here, the Research and Development process (TRL, Stage&Gate ) is unique, classic and relatively cumbersome, with progressive selection and strong natural attrition of proposals. In this model, it is difficult to stop projects once they have passed the – gate – stage of product development. This type of funnel can be found in sectors such as pharmaceuticals and retailing, where innovation ideas are highly selective before the actual development process begins.
