I am working on mapping advice networks in formal organizations, as a method to voice i.e. a PSU specifically. It is looking at leadership i.e. leadership effectiveness (exchange), informal networks(advice networks) and types of voice.

My questions include 2 scales for the same.

How do I best ask questions for and map advice networks? The roster method is not acceptable to the organization. Will the name generator system with questions on interaction, advice and frequency be effective?

Can you advice me on the best method? Please share your experience and any papers too.
