Step seven: As the first session comes to an end, let people know with a bell - but remember that conversations may flow into the next session and try not to be too intrusive. After opening the OST, it largely runs itself, but it is often a time when participants will seek out facilitators for one-on-one conversations. Step eight: To close the OST, invite the session hosts to share highlights, "aha moments" and key learnings with the larger group. If you have time, you can close the session in circle, inviting everyone to share their insights from the process. You may choose to display the templates on the wall for others to be able to read and/or for the graphic recorder to get a sense of the different sessions to incorporate into the mural.
