I think it is a good reminder that these mapping are helpful, not just for sales but also for internal getting buy-in.
I wonder what tool would now be the best or even if there is a business opportunity there. I would use miro/mural at the moment and check for some templates. Anyone knows a good tool? Optimally it would guide you to list people and their function/skillset and then make those maps.
This kind of assumptions mapping can be really helpful in many cases, not just sales. Customer journeys for the user experience, for example. Or for driving change internally in large organisations.
Summary: an exploration of what's involved in drawing a map of the relevant aspects of the customer organization involved in a sale. In addition to the technical evaluation there will be a business team and several decision process owners in the legal, security, and purchasing functions.
