Final answer:
The statement regarding the weakness of MBO due to top management's overinvolvement is false. MBO can fail if not implemented correctly, but this is due to poor management practices, not MBO's intrinsic weaknesses.
Step-by-step explanation:
The statement that the weakest levels of Management by Objectives (MBO) manifest themselves when top management is too involved is false. MBO is a strategic management model that aims to improve the performance of an organization by clearly defining objectives that are agreed upon by both management and employees. Excessive involvement of top management may lead to work overload, conflict, and ambiguity in defining managerial roles, which in turn could create difficult work relationships. However, these are symptoms of poor implementation rather than inherent weaknesses of the MBO approach itself. For MBO to be effective, it's crucial for top management to find the right balance in their level of involvement, ensuring that they support and facilitate employees without micromanaging or overburdening them with excessive control.
