What technological advancement is expected to change managers' jobs?

The technological advancement that is expected to change managers' jobs significantly is the improvement in management information systems. Enhanced management information systems provide managers with more accurate, timely, and relevant data, which in turn facilitates better decision-making processes. These systems integrate and analyze data from various sources, allowing managers to identify trends, monitor performance, and respond proactively to changing business conditions.

The evolution of these systems often includes advanced analytics, artificial intelligence, and machine learning capabilities, which streamline operations and enhance strategic planning. By leveraging these tools, managers can focus more on high-level strategic issues rather than being bogged down by administrative tasks or data gathering, ultimately transforming the role of management into one that is more data-driven and forward-thinking.

In contrast, the other choices do not reflect trends that would positively influence managerial roles. A reduction in collaborative tools or online services would likely hinder communication and efficiency rather than enhance managerial effectiveness. Similarly, the diminished importance of managerial roles suggests a move towards automation or a flat organizational structure, which does not align with the expectation that management will instead evolve and adapt through better information systems.
