There are four types of responsibility centers: cost centers, revenue centers, profit centers, and investment centers. Each center type has a specific role and accountability. Cost centers are accountable for meeting budgeted cost goals, revenue centers are responsible for meeting sales targets, profit centers are accountable for profitability, and investment centers are accountable for both profitability and return on invested funds. Managers of each center type use an individual budget and incremental analysis for decisions like accepting special orders, making or buying products, selling or further processing products, and changes to production or technology.
