One of the huge challenges of being a facilitator is to encourage participation from your participants.
It is a vulnerable position to be in, because you, as a facilitator, need to drive the discussion and encourage outcomes, but what if few people speak or you can only hear the loudest voices which mute all other? Then you are in a big trouble.
This is how you distinguish between experienced facilitators and wannabes.
For experience facilitators, it is important to create activities to encourage extroverts and introverts, the quiet one and the one who needs to speak.
In general, companies need to invest in their employees more to increase their skills and make them more productive and effective!
