The Mumford skills model emphasizes problem solving as a key skill for effective management. Jim's focus on problem-solving abilities aligns with this approach. The trait approach focuses on identifying personality traits that are associated with effective leadership, while Katz's skills approach focuses on three types of skills: technical, human, and conceptual.
