On page 213 of EntreLeadership by Dave Ramsey he writes,
"One of the hallmarks of winning companies is they are very intentional and effective at communication. As a matter of fact the EntreLeader's goal should be to create a company culture of communication. Communication is the grease in the gears. You can have great gears in your company and it will still freeze up, grind to a halt, if you don't put the great of communication into the engine. When the right hand doesn't know what the left hand is going, great frustration and distrust sets in."
