Who to invite is about thinking
in perceptions instead of people.
Invite especially people

Visual and collaborative modelling
➔ Reduce handovers, get first-hand knowledge by collaboration!
➔ Visualise complexity and be aware of cognitive bias!
➔ Only talk about visual things
➔ Room Setup is important
➔ Keep spreading by asking: Who recognises…...?
➔ Start by doing in a safe environment,
else get an experienced facilitator.
➔ There are no Silver Bullets! Pick your tool for the job!
