Final answer:
In modern organizations, power is shifting from traditional hierarchies to network-based structures where brokers play a key role in facilitating interactions, regardless of their position or expertise.
Step-by-step explanation:
The power dynamics in modern organizations are evolving due to the shift from traditional hierarchical structures to flat organizational architectures. In this new paradigm, power is repositioned in the network of the organization. People who hold influence can come from various levels of an organization and aren't necessarily at the top of the hierarchy or recognized experts. This change emphasizes the importance of team dynamics and relationships within the company. These influential individuals are often referred to as brokers because they facilitate interactions and information flow between different parts of the organization, contributing to its effectiveness.
