Explanation:

Forecasting demand and revenues for new variants of existing products is difficult enough. But forecasting for radically innovative products in emerging new categories is an entirely different ball game. There are no past trends to reassuringly extrapolate into the future, just a ton of uncertainty about whether the latent demand that the marketing folk suggested to secure the R&D funding is real or not. And after so much investment, the board is sure that this is the product that is going to become the next cash cow. Sure, you could manage their expectations by reminding them that something like 80% of new products fail and name drop a few of the spectacular flops of Fortune 500 companies.
