In which stage do groups often experience members leaving or new members joining?

The correct stage where groups often experience members leaving or new members joining is the Transition stage. This stage is characterized by significant changes as the group evolves over time. It can involve shifts in membership, which may occur due to various reasons such as members feeling that they no longer fit the group, personal circumstances leading to departure, or positive factors attracting new individuals who can contribute to the group’s goals.

In the Transition stage, the group often reassesses its objectives, dynamics, and overall cohesion as it adapts to the changing makeup. This continual evolution is vital for maintaining the group’s relevance and effectiveness as it navigates challenges and opportunities.

While the other stages involve different dynamics, they do not specifically focus on the influx or outflux of group members. For instance, the Investigation stage centers more on exploration and forming initial interactions, while the Socialization stage involves bonding and establishing relationships among existing members. The Maintenance stage typically deals with the ongoing processes that keep the group functioning effectively, rather than the transitions in membership itself.
