An old addage in the steel industry is, "Measure twice, cut once."
This isn't business and asking a lot of input from a lot of sources when making a decision is asking for trouble.
Trying to discern the ramifications of EVERYTHING is often like herding cats. One must start from a base of convictions and follow that forward while looking at decisions already made.
I do distrust the ability of those who are so enmeshed in trivia and breadcrumbs. With good reason, I might add without going into my own experiences.
