Medico has found that its annual budgets are quickly outdated once actual data is recorded.
Sometimes actual preparations have already begun for the period being budgeted by the

Medico wants the budget to be as up-to-date as possible, and management is willing to
revise budgets as needed. Which budgeting solution would be most appropriate for Medico?
