Final answer:
The statement is false; it is essential for managers to periodically review plans to learn from outcomes and adjust strategies as necessary for successful business management and adaptation to changes (b).
Step-by-step explanation:
The statement that managers don't need to periodically review plans to learn from results and shift plans as needed is false. In the world of business, it is crucial for managers to engage in continuous planning and review. This process allows them to assess the effectiveness of their strategies and make necessary adjustments based on performance indicators and market conditions.
By not periodically reviewing and updating plans, a business may miss out on important opportunities for growth, face unforeseen challenges without preparation, and ultimately fail to meet its objectives. Regular plan reviews also foster organizational learning and can lead to improved decision-making over time.
