Vertical groups are organizational structures where members are arranged in a hierarchy based on their roles or levels of authority. This type of grouping allows for clear lines of communication and decision-making, as each level has specific responsibilities. For example, in a company, a vertical group might include executives at the top, followed by managers, and then employees. In contrast to horizontal groups, which emphasize collaboration across different levels, vertical groups focus on a top-down approach. This structure is commonly found in traditional businesses, government agencies, and military organizations, where clear leadership and accountability are essential for operations.
