1. Start with the “known” gaps.
“Known” gaps are the ones for which there is general agreement about their identity and significance. For instance, we may know that competitor X is about to introduce their new product which is 20% faster than any product that we have. Since there has been a press announcement, live demonstrations which seem to confirm the claims and an established track record for the competitor, we can firmly believe that the product and the claims for it are real. Furthermore, we know that our customers highly value performance. Hence, this is a gap that is well characterized and is significant to our competitive position.
