In our Stanford d.school class on designing rituals for organizations, we gave some case studies to student groups, to have them play the manager role and create a quick ritual to deal with a situation at work.

One group had the case of having just fired a disruptive employee from their team. What should the manager to do, to smooth this transition and recognize the firing?

This is one of the ritual designs proposed:

This ritual mixes recognition of the problems the disruptive employee posed to the group, while also a focus on what the person had contributed. It aims for a break with the past, but some continuity of the good things.

And it has roasting marshmallows as its conclusion!
