The document defines power as the capacity for an individual (A) to influence another individual (B) to act according to A's wishes through B's dependency on resources controlled by A. It contrasts leadership, which focuses on goal achievement through compatible goals and downward influence, with power, which is used as a means to achieve goals through the dependency of followers and lateral and upward influence. The bases of power discussed include coercive, reward, legitimate, information, expert, referent, charismatic, and power through coalitions. Dependency is key to power, with greater dependency resulting in greater power over individuals. Politics in organizations involves behaviors to influence resource distributions that are not formally required but affect advantages and disadvantages.
