Three Important Factors for a Successful Team

Strong leadership
Ideally, there will be a natural leader in the team. He or she will send out emails, organize meeting times, prioritize tasks, and delegate them appropriately throughout the team.
The leader should be sensitive to allow other members to take responsibility and control of their own work, as well as recognizing them for their achievement. This will motivate them to take the task in as their own and accomplish it to the best of their ability.
Commitment
There should be unanimous commitment from each and every team member: to be successful with the project or mission at hand. Commitment means putting in a fair share of time and work, and going above and beyond if it so requires. A team should accept no less from its individual members to perform efficiently.
Rapport
A team should have a comfortable level of social rapport to work together. This reduces team friction, and allows members to let down their shell. With this, members should be more comfortable speaking out on matters and critiquing others’ work or ideas. It’s important to create an environment where people won’t be judged for difference of opinion. Also, a bonded team can push the bounds of their creativity together during group brainstorming.
