Is it me or is the message of this article contradictory?
The ending seems to be to recommend "big data" or in most business terms "just analyse the (limited) data you have and watch for trends" however the core message is that when bringing in a new product one has to look at the data that one doesn't have because there won't be sales data for a new product or service and predictions for uptake of a new product or service are often vague at best.
