According to management theorist Robert Katz, management comprises three critical skill sets: technical, human, and conceptual. The development of human skills—which could be perceived as a combination of social, interpersonal, and leadership skills—is central to the success of a manager.
Leadership
Over the years, the common definition of management has become less specific, as managerial functions can include staffing, directing, and reporting. Modern companies have fewer layers of management, as these companies instead rely on the delegation of responsibilities and authority to achieve goals. As a result, businesses often speak of "leading," or guiding, people rather than giving instructions for every action. Leading people represents a central component of human skills.
Under this definition of management, leadership is actually a subcategory of management. Management characterizes the process of leading and directing all or part of an organization, often a business, through the deployment and manipulation of resources (human, financial, material, intellectual or intangible).
Human skills differentiate a manager from a leader. A manager is simply manipulating resources to achieve a given objective, while a leader appeals to the human side of employees to generate creativity and motivation.
These concepts of "manager" and "leader" can be distinguished within a team setting. A team leader who is unconcerned with team members' needs or who has a personal agenda that is perceived to be more important than the team's goals may be considered more of a manager than a leader, with the possible outcome of being estranged from team members. Conversely, team leaders who are admired and loyally followed are those who show concern for the team members as individuals with real needs and who place their team above their own personal agendas.
Communication
Realistically, most organizations need leaders who can view their teams analytically and objectively, evaluating inefficiencies and making unpopular choices. However, it is misleading to think that a manager has to be distant from or disliked by subordinates to execute these responsibilities. Creating a healthy environment conducive to development, criticism, and higher degrees of achievement simply requires strong human skills, particularly in the realm of communication.
The "four sides" communication model
This model provides a theoretical framework for the act of communicating, which lies at the heart of effective management. A sender communicating a message to a receiver is not simply transmitting factual information; self-image, context, charisma, and the relationship between the two people also impact the reception of the message.
Interpersonal skills and communication skills lie at the center of human-based managerial considerations. Good managers understand not only what they are trying to say but also the broader context and implications of saying it. Empathy, self-reflection, situational awareness, and charisma all play integral roles in communicating effectively and positively.
