A director is a person from a group of managers who leads or supervises a particular area of a company, program, or project. Companies that use this term often have many directors spread throughout different business functions or roles (e.g. director of human resources).
Often, controllers oversee the accounting, audit, and budget departments. Treasurers and finance officers direct their organization's budgets to meet its financial goals. They oversee the investment of funds. They carry out strategies to raise capital (such as issuing stocks or bonds) to support the firm's expansion. They also develop financial plans for mergers (two companies joining together) and acquisitions (one company buying another).
