Feed-forward refers to providing control and direction to subordinates before expecting an output. It involves providing documents for review and ex post information before any changes in output occur. Feed-forward systems monitor inputs to ensure they are as planned, unlike feedback systems which measure outputs and provide corrective actions. Preventive control focuses on anticipating possible deviations and preventing them through qualified managers and applying management principles to minimize errors and improve performance. Profit and loss statements show a company's revenues, expenses, and profits/losses over an accounting period. Companies can control certain items like inventory to increase profits.
