Case consultations are a way of finding solutions to professional and personal problems in a short time with the help of external perspectives. Originally developed in the field of social work as collegial case consultation during intervisions, these formats have also proven useful in business contexts.
In terms of time, case consultations could also be treated as a "nugget". From 30, 60 to 90 minutes, anything is possible. Only here I would not provide content as input, but rather facilitate and structure a process. This would be a special form of facilitation, or a special form of guiding group feedback. Case consultations can be useful in both profit and non-profit organizations if a problem is to be discussed by a group in a structured way.
