An organization chart is a graphical representation of the functions and structure of a company. The charts also show the link between various positions and are an easy way to see how work flows within a company. Organization charts are classified into three types: structural charts, functional charts, and position charts. There are seven different types of organizational structures. Regardless of an organization's structure, org charts are extremely valuable when a company is thinking about reorganizing its personnel or changing its management structure. Most importantly, org charts allow workers to see how their positions fit into the larger structure of the firm.
