Team Leader/Supervisor

Who is a better coach - The Team lead/ Supervisor or the Process/Product trainer?

I see that "Team Leader".

the direct supervisor , but the more better is your self and how you learn and your ability to not wait other to come and teach you , but you go and hunt the info from any person even your colleage or your subordinate

anyone that would make employees would feel that he is a team player, who have in market experiance, yet at the sametime firm would do very well in my point of view

Process trainer theory knowledge Team lead practical knowledge People learn better through practical knowledge .

We can not compare the three and so for a simple reason:

Each person carries specific tasks each person leads to the success of a particular team.

Everyone has duties to each of these three priorities.

Profile opinion are all important and we can not shown by one of them at the expense of the other.

Process Trainer

Not sure,

the team leader suggests a management skill and talent to handle the staff you supervise.

the process/product trainer suggest a technical skills and knowledge about process and product.

Now look at it from the point of view of your team:

if i was a junior staff, i don't mind reporting to team leader or process trainer.

but if i was a senior staff or expert, i would prefer team leader than process trainer.

I think it really depends on what coaching is given and in what context. For example Technical training/coaching is best done by qualified trainers and process coaching be it busines or logistics is best done by a team lead or a supervisor. This would be my approach.  

Sure, the team leader coz he's the one who perfectly knows the product from a side  and his team from on other side
