Hierarchy is a pyramid-like ranking of ideas, individuals, items, etc., where every level (except the top and the bottom ones) has one higher and one lower neighbor. Higher level means greater authority, importance, and influence. Having a structure consisting of multiple levels, a hierarchical business structure would mean that the chain of command looks like a pyramid, with a large base of workers, who are directly supervised by the smaller level above them, who are in turn supervised by the level above them, continuing on to the top ranking officer such as the company President or CEO. Alternatively, anything which can be broken down into a series of levels which range from broad to specific can be considered hierarchical.
