There are many roles to management teams... I dislike labels, but at same time i cant imagine a management team with out these roles. Alot of ppl are a mix of all these traits....
Implementer: Well-organized and predictable. Takes basic ideas and makes them work in practice. Can be slow.
Shaper :Lots of energy and action, challenging others to move forwards. Can be insensitive.
Completer/Finisher: Reliably sees things through to the end, ironing out the wrinkles and ensuring everything works well. Can worry too much and not trust others.
Plant: Solves difficult problems with original and creative ideas. Can be poor communicator and may ignore the details
. Monitor/Evaluator: Sees the big picture. Thinks carefully and accurately about things. May lack energy or ability to inspire others.
Specialist: Has expert knowledge/skills in key areas and will solve many problems here. Can be disinterested in all other areas.
Coordinator: Respected leader who helps everyone focus on their task. Can be seen as excessively controlling.
Team worker :Cares for individuals and the team. Good listener and works to resolve social problems. Can have problems making difficult decisions.
Resource/investigator: Explores new ideas and possibilities with energy and with others. Good networker. Can be too optimistic and lose energy after the initial flush.
