Direct supervision and observation is the oldest technique of controlling where the supervisor directly observes employees and solves problems. This allows the supervisor to get first-hand information and a better understanding of the workers. Financial statements like the profit and loss account and balance sheet are prepared and used to control the organization by comparing current figures to previous years' figures. Budgetary control is done through budgets for all aspects of the business by a budget committee to facilitate planning and control. Break-even analysis finds the point where there is no profit or loss to evaluate performance and take corrective actions.
