Step-by-step explanation:
The category that is ranked with the highest amount of emphasis in management is planning. Planning involves setting goals, making decisions, and developing strategies to achieve those goals. It is the foundation of the management process and provides direction for all other managerial activities.
For example, when a company plans to launch a new product, the management team sets goals, creates a timeline, allocates resources, and develops a marketing strategy to ensure the success of the product.
While controlling, staffing, and other functions are also important in management, planning receives the highest level of emphasis as it sets the course for the organization.
