All organizations are hierarchical. At each level people serve under those above them. An organization is therefore a structured institution. If it is not structured, it is a mob. Mobs do not get things done, they destroy things.
Theodore LevittThough progress starts with the imagination, only work can make things happen. And work itself works best when fueled, again by the imagination.

Theodore LevittEvery major industry was once a growth industry. But some that are now riding a wave of growth enthusiasm are very much in the shadow of decline. Others that are thought of as seasoned growth industries have actually stopped growing. In every case, the reason growth is threatened, slowed, or stopped is not because the market is saturated. It is because there has been a failure of management.
