Which of the following is NOT a major function of a manager under leading?

The major functions of a manager under the leading aspect primarily focus on influencing and guiding employees towards achieving organizational objectives. Stimulating employee engagement, setting organizational goals, and providing feedback to employees are all essential components of effective leadership. These functions ensure that employees are motivated, understand the direction of the organization, and receive the support they need to perform optimally.

Designing the organizational architecture, however, falls more under the planning and organizing functions of management rather than leading. This aspect involves the structural framework of the organization, including how different roles and responsibilities are arranged and coordinated. While it is a crucial part of management, it doesn't directly pertain to the leading function, which is more about interpersonal relationships and motivation within the team. Thus, the correct answer identifies a task that does not align with the leading function of management.
