Jenny Cham is a lead user experience architect at EMBL-EBI who facilitates workshops using techniques like gamestorming. Effective facilitation includes giving clear objectives and time boundaries, ensuring participants understand the task, and promoting discussion. Facilitators should involve all participants, ask questions to clarify outcomes, and reflect participants' ideas back to the group rather than providing their own answers. Proper facilitation requires suitable workshop spaces, healthy snacks, and good logistical support.
