Management accounting provides information to assist managers in planning, directing operations, and controlling the organization. It involves recording, analyzing, and reporting financial and operational data to help managers make informed business decisions. The management accountant's role is to identify, measure, analyze, interpret, and communicate financial and non-financial information relevant for decision-making, planning, and control. Key tools used include budgets, variance analysis, costing techniques, and reports to help managers with tasks like setting objectives, allocating resources, and evaluating performance.
