It is useful to shift this thinking, to focus instead on the activities the human-centred designers do that have a cultural impact within their organisations. We help people understand different perspectives, collaborate, learn and iterate, have a growth mindset, reach agreement across the organisational silos, etc. By acknowledging these and other things as a significant part of what human-centred designers do you can reframe your own and others perspective of your role. You not only collaborate with others, but you enthuse others with the ability to collaborate.
