Yes, there are differences, and you mentioned some. But I believe that the alternative approach I described can work for commercial products and where the founder observes the need. Indeed, as I mentioned, the approach has a severe filter; if the founder can't observe a need where the first good or a much better solution will be a "must have", then back to (1) and try again. Getting an idea all the way through the filter might be challenging. But, it seems to me that for an idea that does get through the filter, execution should be routine and project success quite likely.
