Hindsight is always 100% right, and a survey of 1 is always 100% right. It is so much harder to predict what to do next. You might hear the expression “can’t see the forest from the trees.”
This expression means that there are just way too many variables to consider. There are two ways that I determine a course of action. The first one anyone can do. Find a variety of people that don’t have a stake in the answer and ask them the question. What would you do, or what do you think? Their feedback will provide you with insights that you might otherwise lack.
The second way is a bit harder. You have to find the right person, and they have to be an extreme pessimist or optimist. If you are giddy over the project, ask a pessimist what could go wrong. If you are concerned, then ask an optimist.
The feedback plus your perspective are bound to help produce a better result.
