A committee or commission is a body of one or more persons subordinate to a deliberative assembly or other form of organization. A committee may not itself be considered to be a form of assembly or a decision-making body. Usually, an assembly or organization sends matters to a committee as a way to explore them more fully than would be possible if the whole assembly or organization were considering them. Committees may have different functions and their types of work differ depending on the type of organization and its needs.
