The answer is Interpersonal skills.
Interpersonal skills are crucial at every level of management because they involve the ability to communicate, interact, and work well with others. These skills are essential for building relationships, resolving conflicts, and leading teams effectively, making them important for managers at all levels.
Conceptual skills are more important at higher levels of management, where strategic planning and understanding complex situations are required. While important, they are not as universally necessary at every level as interpersonal skills.
Decision skills are important for managers, but the level of importance can vary depending on the managerial position. While all managers need to make decisions, the complexity and impact of these decisions can differ.
Technical skills are more critical at lower levels of management, where specific knowledge and expertise in a particular area are required. As managers move up the hierarchy, the need for technical skills decreases compared to interpersonal and conceptual skills.
