How do you organize and manage your job specific training programs

I want to know how you organize and plan your training programs. For example Customer Service Training includes many modules grouped together to instruct an individual on how to perform that role. How do you gather the information and manage it?

The current way that I do this is to analyze the role and identify key task and topics then break those down more specifically in to sub categories (or modules) and then key point in each module.

I looking for specifics on how you do it. What documents if any do you use? Who do you talk to? How do you prioritize the material?
