What is a notable disadvantage of zero-based budgeting?

Zero-based budgeting can indeed introduce rigidity into the budgeting process. This approach requires each department or unit to start from a "zero base" and justify every expense for the upcoming period, rather than simply adjusting the previous period's budget. While this can lead to a thorough examination of all expenditures and potentially highlight inefficiencies, it can also result in a more rigid environment where managers may feel constrained by the need to justify every line item comprehensively.

The requirement to justify all expenses can lead to extensive planning and analysis, which, while beneficial in some contexts, may slow down the budgeting process and hinder flexibility. The focus on justification rather than ongoing operational adjustments can limit the ability of a business to adapt rapidly to changing circumstances or opportunities, such as shifting market conditions or unforeseen expenses.

In contrast, options highlighting managerial involvement, flexible adjustments, and the identification of inefficiencies illustrate some advantages of zero-based budgeting. However, when seeking to understand its disadvantages, the rigidity introduced by the process is a significant concern that can impact the agility and responsiveness of an organization.
