Is budgeting a waste of time?

Budgeting is not waste of time as long as it is performed after taking into account unexpected events,changes,and uncertainties.
Rather budgeting is a very effective way of efficient use of resources.if businesses fail to budget, they can't have a clue how much resiursec are available and where the business has to spend first(prioritising your expenses/payouts)
budgeting is all about planning and implementation,and if you fail to plan,you plan to fail.
