a friday quote: the test of an organization

What I really enjoy most about this quote is the relational component of it.
"No organization can depend on genius; the supply is always scarce and unreliable. It is the test of an organization to make ordinary human beings perform better than they seem capable of, to bring out whatever strength there is in its members, and to use each man’s strength to help all the others perform. The purpose of an organization is to enable common men to do uncommon things." - Peter F. Drucker, Management (HarperCollins), Reader’s Digest, p. 209
When have you seen the abundance of relationships or the lack of them affect a home, a company, a team, or a church?
