In which development stage do team members start to work towards solving problems collaboratively?

The correct choice is Performing. During the Performing stage, team members have established a strong sense of cohesion and trust, allowing them to effectively work together towards common goals. In this phase, individuals are fully engaged in their roles and collaborate actively to solve problems and tackle the tasks at hand. The focus is on achieving results, and the team operates with a high level of autonomy and motivation.

In contrast, during the Forming stage, team members are just coming together and may still be getting to know one another, which can lead to uncertainty about roles and responsibilities. The Norming stage focuses on establishing norms and building relationships, where collaboration begins, but it is not yet at the level of coordinated effort seen in Performing. Lastly, the Adjourning stage involves disbanding the team after achieving its objectives, rather than ongoing collaboration and problem-solving. Each stage represents a distinct phase in team development, with Performing being where collaborative problem-solving reaches its peak.
