What management function involves assigning tasks developed under planning to groups within the organization?

The management function that involves assigning tasks developed under planning to groups within the organization is organizing. This function is crucial as it lays out how various resources, including personnel, are allocated to achieve the objectives set in the planning phase. Organizing encompasses the establishment of a structure within the organization where tasks are assigned and coordinated, allowing for effective implementation of plans.

Through organizing, managers identify roles and responsibilities, form teams, and establish communication channels, which helps streamline operations and clarify expectations among employees. This makes it easier to achieve the strategic goals outlined during the planning phase because everyone understands their specific contributions to the overall objectives.

Other management functions, such as planning, involve setting objectives and determining a course of action, while leading is about motivating and directing personnel. Controlling pertains to monitoring and evaluating progress toward the goals set in the planning stage. Each function plays a distinct role in management, but organizing specifically focuses on the allocation and assignment of tasks, making it the correct answer in this context.
