About three years ago I found myself in a situation where I asked myself this same question. I was leader a UX team and was wrestling with trying to increase overall impact in the organisation.
Are we getting the impact from UX that we want? Or do we know what we want?
After a discussion in Sweden and on various Slack groups, I decided to ask a wider group of people and created the European UX impact survey to try to get some better information.
Looking at the results and through all of the conversations since then, I have come to realise that all although this is interesting metric for organisations it is an oversimplified view.
