This document discusses using crowds to develop and assess business opportunities. It provides examples from TDC A/S of aggregating stakeholder insights to more accurately estimate performance measures than individuals. Crowds can predict issues better than firms and also assess business opportunities through a crowd approval model evaluating internal and external fit. An iterative process is described of using crowds for ideation, assessment, selection and development of initiatives to interact with management. The possibilities of using crowds in TDC A/S are discussed.
