What term defines the situation where the combined output of two individuals exceeds their individual output?

The term that defines the situation where the combined output of two individuals exceeds their individual output is synergy. Synergy refers to the phenomenon where the interaction or collaboration between two or more parties results in a total effect that is greater than the sum of their separate effects. In a business context, this can occur when teamwork leads to enhanced creativity, shared strengths, or more effective problem-solving, resulting in outcomes that individuals could not achieve alone.

The concept emphasizes the value of collaboration and cooperation, illustrating how collective efforts can lead to improved efficiency and greater effectiveness. This is particularly important in team environments where diverse skills and perspectives can complement each other, leading to innovative solutions and enhanced productivity. In contrast, accountability relates to the responsibility individuals have for their actions, productivity typically refers to the measurement of output relative to input, and "none of the above" does not apply since synergy accurately describes the situation described in the question.
