Which of the training professionals' roles do you believe is the most difficult to learn? Which is the easiest?

Answer and explanation:

There are several roles trainers could adopt while handling trainee groups but the most important are: instructional designer, technical writer, and needs analyst. From the three of them being a needs analyst could represent the most challenging because it implies collecting information of different individuals to identify what they are lacking and based on that information collect data that can be useful for their learning process.

On the other hand, being a technical writer could be the easiest since professional trainers manage their field of study. They tend to portrait their knowledge in written documents using technical terminology suiting it to the audience they are going to work with.
