I wish there was more detail about the pain-point-finding process. As is, simply looking for examples of current pain points is very prone to cognitive bias -- if you go looking for a pain point, you'll find one, but how do you quantify the intensity of pain and willingness to change solutions? Maybe more of an overall competition-assessment strategy (rather than a specific pain-point-search) -- if you research the current shortcomings AND high points of current solutions you'll have a much better understanding of the value your product can add.
