Successful teams have the functional skills to lead a task, benefit from diversity, and are led in a way that creates time and space for reflection; the ability to take stock periodically, of the task and of the way in which the team is engaged in delivering it. Your stakeholder analysis [HYPERLINK] should help you assemble the most appropriate team and identify how the team interacts and relates to other stakeholders like sponsors, services users, etc.
