Repeat the above until either you have developed a sound hypothesis, you have pivoted and developed a new hypothesis which you will test, or you have abandoned the exercise as the hypothesis has no validity and it can’t be saved.|
Doing the above will cost time and resources, but so will diving straight in and building something in the hopes that someone will like it and buy. Building something in the hope that someone will buy it is not a sound strategy, it is wishful thinking.
