Visual metaphors that are too close to what your business actually does can trigger conversations that stall.
It is important to pick an analogy that hasn’t been used in your organisation before and isn’t close to your business. For example, if you are an airline, using air travel metaphors and images of aircraft, may see colleagues discussing the design of a wingtip on an airliner. That won’t help enhance the passenger experience; the strategic topic you really wanted your people to be talking about. That metaphor won’t fly, others will.
