Leadership structures refer to the organized frameworks that define how leadership roles and responsibilities are distributed within an organization. These structures can vary widely, from hierarchical models with clear chains of command to more decentralized approaches that promote collaboration and shared decision-making. Each structure influences how decisions are made and how information flows within the organization. In a hierarchical structure, leaders at the top have the most authority, while lower levels follow their directives. Conversely, in a flat structure, such as those often seen in startups, employees may have more autonomy and input in decision-making. Understanding these structures helps organizations optimize their leadership effectiveness and employee engagement.
