Which of the following is NOT one of the four types of budgets?

The correct answer is identified as Program Increment Budget, which is not traditionally recognized as one of the four main types of budgets in public works or governmental financial management.

Zero Based Budgeting involves starting from a "zero base" and justifying all expenses for each new period, ensuring that all activities receive funding based on needs rather than previous budgets. Line Item Budgeting breaks down expenses by specific line items, allowing for clear categorization and monitoring of spending. A Rolling Budget is one that is continuously updated by adding a new time period as the last one concludes, helping organizations maintain a forward-looking financial view.

The Program Increment Budget, while it may be relevant in specific contexts, especially in agile project management or software development, does not fit into the established categories of budgeting types commonly utilized in public works or municipal finance. Thus, it stands out as not belonging among the four typical types of budgets, emphasizing the importance of understanding the foundational concepts of budgeting methods within public administration and management.
