When is forming a team not advisable?

Forming a team is not advisable when individual work can be completed effectively. This scenario suggests that the task at hand can be managed efficiently by individuals without the need for collaboration or the advantages of diverse viewpoints that a team might offer. In cases where the work can be done more swiftly and successfully by individuals, it typically means that the complexity of the task does not warrant the additional time and resources required to coordinate and manage a team.

In contrast, the other options indicate situations where teamwork is beneficial. For example, tasks that require collaboration often involve complex or multifaceted challenges that can be solved more effectively by leveraging different skill sets and perspectives. Similarly, when diversity of opinion is needed, teams can provide a richer array of insights and innovative solutions, whereas individual work would lack this broad perspective. Lastly, when there is a clear team goal, teaming up can enhance motivation and accountability, enabling individuals to contribute toward a shared outcome, which enhances their performance and commitment.
