Step-by-step explanation:
When a CEO sketches out the reporting relationships during a management reorganization, this action is an example of organizing. Organizing is one of the four principal functions of management, along with planning, leading, and controlling. In this context, the CEO is arranging the structures and allocating resources, including personnel, to optimize efficiency and prepare the organization for the changes. This process often involves creating organizational charts that visually represent the company structure post-reorganization, clarifying roles, responsibilities, and lines of communication.
