1. The three levels of managers are top-level managers, middle-level managers, and low-level managers. They are categorized according to different positions and rankings based on their performance.

Top managers are considered as an ultimate authority who prepares planning and policies for an organization. Top-level managers include the Chief Executive Officer, the Board of Directors, and the Vice-President. Upper managers need three essential skills like management skills, interpersonal skills, and decision-making skills. In management skills, they will control and direct the activities of all departments and offer the employees with necessary instructions. An interpersonal skill manages a personal relationship with subordinates, clients, and officers. In decision-making skills, the managers have the power to take small and big decisions in any situation.

Middle managers are considered as subordinates of upper management and are in charge of training and development of lower employees. This type of manager includes production managers, general managers, and branch managers. The skills essential for middle managers are excellent communication, self-actualization, and quick learning. Excellent communication is essential for a leadership function which requires a supporting cooperative behavior. In self-actualization skill, the managers will cooperate with other managers to bring about new ideas and solve problems. Quick learning skills seek opportunities to learn knowledge and technical know-how.

Lower managers are the first line of managers and they communicate the fundamental problems of the firm to superior officers. They consist of foremen, supervisors, and section leads. The skills essential for lower-level managers are technical skills, communication skills, and problem-solving skills. Technical skills help the managers to do a wide variety of operating procedures and plans to accomplish the goal. Communication skill helps the manager to share out the information among the team and can relate well with the employees.

2. A good manager has the ability to motivate the entire team and enhance strength and improve weaknesses. A good manager has a vision of the company's goals and can make changes and communicate with the employees to fulfill the goals successfully. When the employees are struggling with any consigned work, the manager will find a solution to their problem and make accurate decisions.

For example, the manager of a construction field regularly boosts and encourages the company's services by using local and digital advertising. They will try different strategies and promote the company and its products and services. Also, the manager will improve new technologies and tools for optimizing better marketing campaigns.
