Be Transparent and Honest with Your Business Partners
I don't just mean "business partners" as people with whom you entered into business, or even other companies with whom you have a partnership arrangement. I mean everybody you work with in order to get the project completed: you should treat all of these people as peers, whose help you need, and who need your help in order to deliver a quality product to your customers. If you want their respect, honesty, and help you need to be respectful, honest, and helpful to them.
Currently, this sounds like the sort of hackneyed non-lesson in working with others that has remained unchanged for the last few thousand years: "do as you would be done by." But bear with me; there's more science to it than that.
Have you ever described someone, or heard someone described, as "clueless"? They "just don't get it"? You've probably experienced the correspondence effect—http://en.wikipedia.org...
