Which component of an information system is used to produce an operational budget?

• A. Transaction processing system (TPS)
• B. Financial reporting system (FRS)
• C. Management reporting system (MRS)
• D. General ledger system (GLS)

Answer: (C)

Operational budgets are internal planning documents that guide day-to-day activities like production, purchasing, and staffing. To create these budgets, managers rely on information designed for planning and performance monitoring—data that aggregates forecasts, cost estimates, and expected resource usage. The management reporting system provides exactly this internal perspective. It delivers budget reports, variance analyses, and performance metrics tailored for managers, pulling together inputs from forecasting, cost data, and operational schedules to show how resources should be allocated and how actual results compare with targets. This focus on planning and internal decision-making makes it the primary tool for producing an operational budget.

In contrast, a transaction processing system records every day-to-day event and feeds data to other systems; it isn’t built to generate comprehensive budgeting views. The general ledger stores accounts and postings for financial statements rather than detailed planning reports. The financial reporting system focuses on external financial statements and compliance reporting rather than internal budgeting and performance management.
