The document provides an overview of budgeting methods used in higher education, including activity-based budgeting. It discusses the University of Michigan's hybrid budget model, which incorporates elements of activity-based and discretionary budgeting. The model aims to link revenues and costs to the units generating activities, while also allowing central discretionary funds to support university priorities. A review found the model balanced unit autonomy with university alignment of goals, but recommended improved communication about the budget system.
