What term refers to cooperative interaction resulting in a combined effect?

The term that refers to cooperative interaction resulting in a combined effect is synergy. Synergy describes when multiple elements or individuals work together in such a way that their combined output is greater than the sum of their individual contributions. This concept is often used in various fields, such as biology, business, and social sciences, to illustrate how collective efforts can lead to enhanced outcomes compared to separate actions.

In contexts like team dynamics, for instance, synergy can occur when team members bring different skills and perspectives to a project, leading to innovative solutions and improved performance. This is distinct from collaboration, which focuses more on the process of working together rather than the resultant enhancement of effectiveness. While consensus and coalition involve agreement and unity of purpose, they do not specifically imply the heightened collective impact that synergy emphasizes.
