team leader

A team leader provides guidance and instruction to a working group about a project or portfolio of projects. They are in charge of delegating work, overseeing progress towards goals, and coaching team members as needed. Team leads often serve as de-facto mentors for the team, even if they don't have a manager title
The team leader monitors the quantitative and qualitative achievements of the team and reports results to a manager. The leader often works within the team, as a member, carrying out the same roles but with the additional 'leader' responsibilities – as opposed to higher-level management which often has a separate job role altogether. They may also be considered line management. In order for a team to function successfully, the team leader must also motivate the team to "use their knowledge and skills to achieve the shared goals". When a team leader motivates a team, group members can function in a goal-oriented manner. A "team leader" is also someone who has the capability to drive performance within a group of people. Team leaders utilize their expertise, their peers, influence, and/or creativeness to formulate an effective team.
Scouller (2011) defined the purpose of a leader (including a team leader) as follows: "The purpose of a leader is to make sure there is leadership … to ensure that all four dimensions of leadership are [being addressed].” The four dimensions being: a shared, motivating team purpose or vision or goal, action, progress and results, collective unity or team spirit, and attention to individuals. Leaders also contribute by leading through example.
