The budget is used primarily to allocate resource inputs. Managers use the bud¬get for planning the future and reducing uncertainty about the availability of human and material resources needed to perform department tasks. Computer-based statis¬tical reports are used to control outputs. These reports contain data about output volume and quality and other indicators that provide feedback to middle manage¬ment about departmental results. The reward system and quality control system are directed at the production process. Quality control systems specify standards for employee participation, teamwork, and problem solving. Reward systems pro¬vide incentives to meet goals and can help guide and correct employee behavior. Managers may also use direct supervision to keep departmental work activities within desired limits.
