#4 starts happening almost magically when you reach a level of “maturity” where you are okay to cede control. You can visualize it as a Venn diagram where you have your bubble of what you think is the perfect system/product. Now every other person will have their own bubble and it will never overlap perfectly. #4 involves getting the best execution in the overlapping space and some bits of all the non-overlapping spaces. Suddenly you have an inclusive and almost always, better product which is more than your initial bubble. Everyone is vested in it. Everyone is fulfilled and magnified.
