Independence and Neutrality
The most important benefit is that the facilitator offers an independent view. The external facilitator is completely neutral and this assures fairness and balance during the process. This enables a skilled facilitator ask difficult questions that other people may hold back from asking. Asking the difficult questions and engaging the people in getting to the truth of a matter is what skilled external facilitation requires.
Holds the agenda
A skilled facilitator ensures that the agenda, as much as is possible, is adhered to. This ensures that the process does not get mired or stuck in an unhelpful cycle, rather the process moves forward to an acceptable outcome.
Situations requiring facilitation requires an environment where people can be encouraged to be open; to ensure this confidentiality within the room and especially from the facilitator is essential to build up trust
Skilled facilitators are very effective at negotiating and overcoming difficulties which may occur during the process. Usually these situations arise due to tense and difficult emotional responses at certain points. External facilitators have a good understanding of interpersonal dynamics and human psychology, and apply appropriate techniques to defuse highly tense situations.
