Training plays an very important role in team success, they basically many training methodologies which can implemented, I have some of them discussed here.

1) If the team leader is well versed with the knowledge then it is better to go for a class training.

2) They are possibilities that some of the associate may not understand the class room training in this cases you can go for one on one training.

3) Other is mentoring were you can sit beside the employee and explain everything.

4) The major difference between the mentoring and class room training : in the class the knowledge passed to every one on equal basis keeping that everyone is in same page and each of them is capable of understanding, were as mentoring is after the knowledge is already based then you are particularly training in specific knowledge.
