What are the three types of budgets in organizations where research is purchased and cost containment is crucial?

In organizations where research is purchased and cost containment is crucial, the three types of budgets typically used are incremental budgets, zero-based budgets, and activity-based budgets. Incremental budgets adjust previous budgets for new expenses, promoting stability. Zero-based budgets require all expenses to be justified from scratch, ensuring that only necessary expenditures are funded. Activity-based budgets focus on the costs of specific activities, aligning resources with strategic goals and improving cost efficiency.
