TEAM ROLES:

  Meredith Belbin, in her book Team Role Analysis published in 1981, proposed nine team roles required for successful teams: 

1. Coordinator: This person will have a clear view of the team objectives and will be skilled at inviting the contribution of team members in achieving these, rather than just pushing his or her own view. The coordinator (or chairperson) is self disciplined and applies this discipline to the team. They are confident and mature, and will summarize the view of the group and will be prepared to take a decision on the basis of this.

2. Shaper:
The shaper is full of drive to make things happen and get things going. In doing this they are quite happy to push their own views forward, do not mind being challenged and are always ready to challenge others. The shaper looks for the pattern in discussions and tries to pull things together into something feasible, which the team can then get to work on.

3. Plant
This member is the one who is most likely to come out with original ideas and challenge the traditional way of thinking about things. Sometimes they become so imaginative and creative that the team cannot see the relevance of what they are saying. However, without the plant to scatter the seeds of new ideas the team will often find it difficult to make any headway. The plant’s strength is in providing major new insights and ideas for changes in direction and not in contributing to the detail of what needs to be done.

4. Resource investigator:
The resource investigator is the group member with the strongest contacts and networks, and is excellent at bringing in information and support from the outside. This member can be very enthusiastic in pursuit of the team’s goals, but cannot always sustain this enthusiasm.

5. Implementer:
The individual who is a company worker is well organized and effective at turning big ideas into manageable tasks and plans that can be achieved. Such individuals are both logical and disciplined in their approach. They are hardworking and methodical but may have some difficulty in being flexible.

6. Team worker: The team worker is the one who is most aware of the others in the team, their needs and their concerns. They are sensitive and supportive of other people’s efforts, and try to promote harmony and reduce conflict. Team workers are particularly important when the team is experiencing a stressful or difficult period.
 7. Completer Finisher: The Completer Finisher is a perfectionist and will often go the extra mile to make sure everything is "just right," and the things he or she delivers can be trusted to have been double-checked and then checked again. The Completer Finisher has a strong inward sense of the need for accuracy, rarely needing any encouragement from others because that individual's own high standards are what he or she tries to live up to. They may frustrate their teammates by worrying excessively about minor details and refusing to delegate tasks that they do not trust anyone else to perform.

8. Monitor evaluator:
The monitor evaluator is good at seeing all the options. They have a strategic perspective and can judge situations accurately. The monitor evaluator can be overcritical and is not usually good at inspiring and encouraging others. 
9. Specialist: This person provides specialist skills and knowledge and has a dedicated and single-minded approach. They can adopt a very narrow perspective and sometimes fail to see the whole picture. (Note: the specialist is not considered a team role).
