This document discusses budgeting and budgetary control. It defines a budget as an estimate of future costs and revenues over a period of time, and explains that budgets help prioritize spending, identify waste, and achieve financial goals. Budgetary control involves comparing actual performance to planned budgets and taking corrective actions when there are variances. The objectives of budgetary control are planning, coordination, and control. Managers use budgetary controls for financial forecasting, budgeting, and variance analysis to control project expenses.
