Information management is an essential part in the public budgetary process. This paper analyzes the theoretical basis, tools, and consequences of information management throughout a budget cycle. Budgeters and decision makers need necessary financial data related to all types of revenues and expenditures, economic conditions, and agency needs, among other factors. From an organization theory perspective, budget agencies face a great number of uncertainties and constraints throughout each phase of a budget cycle. Using appropriate budgeting techniques and approaches, they collect, analyze, and use necessary information to make rational budgetary decisions regarding revenue raising and resource distribution. They intend to attain such goals and objectives as cutting inefficient expenditure, achieving more output and outcome with less input, and attaining oriented societal consequences. Extensive efforts in budget reforms have resulted in considerable productivity in government administration, but at a low level. Continuous efforts are needed for further improvement of performance.
