Budgeting is a systematic approach to planning for effective management by creating comprehensive financial plans for an organization's operations and resources over a specific future period. The main purposes of budgeting are to help attain management's objectives, communicate expectations, aid in detailed planning, and provide a basis for measuring and controlling activities. The key steps in preparing a budget include establishing budget centers and a committee, creating a budget manual, forming a budget committee, determining limiting factors, selecting a budget period and objectives, preparing forecasts, and finalizing the budget. Budgeting provides advantages like compelling planning, coordinating departments, establishing performance evaluations and communication, while limitations include potentially restricting creativity and requiring continuous adaptation.
