The optimal team size often hinges on the nature of the project and the specific objectives to be achieved. Generally, a smaller team of around five to nine members is often considered ideal as it facilitates effective communication, collaboration, and cohesion. Smaller teams can make decisions more swiftly and are more agile in adapting to changes. However, certain complex projects may require larger teams to incorporate diverse skills and expertise. In such cases, effective sub-team structures can be established to maintain focus and efficiency.
