Which type of organization expects important decisions to be made by top-level managers?

The correct answer is hierarchical organizations. In a hierarchical structure, there is a clear chain of command and various levels of authority within the organization. This system expects that significant decisions and strategic direction will originate from top-level management. These leaders are often charged with making decisions that impact the entire organization and ensure that the organization's goals and objectives are met.

In contrast, flat organizations tend to have fewer layers of management, which can lead to a more decentralized decision-making process. Such organizations often empower middle management or even operational staff to make decisions, fostering a collaborative environment.

Matrix organizations blend traditional functional structures with project-based structures, which can create complexities in decision-making. In a matrix setup, decision-making responsibilities might be shared among different managers rather than being concentrated at the top level.

Team-based organizations focus on collaboration and group dynamics, often empowering teams to make important decisions, which can lead to greater innovation and responsiveness but means that top-level managers are not the sole decision-makers.

Overall, the hierarchical structure distinctly supports a top-down approach to decision-making, making it clear that significant decisions are expected to be made by top-level managers.
